User questions & answers

Question:	Would this work with a 10W heater (i.e. a glue gun ) to allow various temperatures to be set
Answer:	The controller is rated at 40 amp max and I think 20 continuous amps I think you should be fine with 8amp. I amusing mine to control a 56 amps max trolling motor drawing on average 12 to 15 amps
Question:	Would it work on a lathe with a 3/4 hp and 120v 6 amp motor
Answer:	Hello, this can't work for 7x12 550w mini lathe control board.
Question:	Will this work for my electric nail drill
Answer:	Please search on YouTube the name of the doc motor and you will find several videos on the controller that will show you how to wire and install it, I have never looked at the description that came with the item
Question:	Will this work on a skill reciprocating saw. Model
Answer:	As long as your pack voltage is at most 12v and you do not go over the max amp for the controller (check the specs to find that out) then you should be ok. I tend to use it with a 39lbs trolling motor powered by a 12v battery I intend to put a fuse between the battery and the controller

User questions & answers

Question:	Would this be able to control the speed on an angle grinder
Answer:	YES, 360 deg
Question:	will this work with a 18" 3 speed floor fan. that runs no more than 4 hrs or less at a time
Answer:	yes it will do 5-35v the pins on the back say 1 to 15v because if you solder them together that is what it will take. (Just read the sixth pic)
Question:	Where is it made
Answer:	Yes, this is what I used it for. I had 17.5v to help control several LED strip lights.
Question:	length of cord
Answer:	I'm not sure if this PWM (Pulse Width Modulation) speed controller would be able to dim LED lights, as it provided very limited speed control for my 12V DC motor (~80-100%). I ended up returning these speed controllers and went with a different PWM speed controller that provided full range speed control (0-100%) for my motors. Additionally, I'm not sure how LED lights would react to pulsed input power.

User questions & answers

Question:

Does it turn down all the way to the OFF position

Answer:

As long as there’s a little room in the box you should be fine. There should be some air flow across the unit and you could always cut a couple of slits in behind where the potentiometer is sticking out. The aluminum heat syncs are ample size and the only thing I’ve noticed is radiant heat similar to other electronic devices enclosed. I’ve had no problems with two of these units and both are enclosed. But err on the side of caution always, air flow holes / slits do wonders . Hope this helped, Oldskool Red

User questions & answers

Question:	Will this work to control the blower speed on a hot blast wood burner
Answer:	The 1203BB DC Motor Speed Regulator controls the speed of a DC motorby adjusting Pulse-Width-Modulated (PWM). It provides a continuous current of 3A to your DC motor or other DC load. Besides, the circuit also includes a 3A fuse. With reverse connection of power supply and control the forward or reverse direction and the stop of DC motor by switch.
Question:	what variable speed switch should i get for a 110v lathe 3/4 hp motor
Answer:	Without a load you will only read the input voltage on the output. One a load is connected you will get an output voltage based on the potentiometer position.
Question:	Does this use PWM or voltage control
Answer:	Question doesn't make sense. PWM by definition is a continuous wave where the duty cycle can vary. Almost all of these type devices pump out a square wave. It can be 'rounded' some by putting a capacitor across the output (ie, a filter) - the final shape to be determined by current draw and capacitor size. In hardware discrete is often 'digital.' To some a square wave looks 'digital', but, PWM is not discrete and the wave is actually generated with analog electronics, not digital (in this device). An Ardunio or other processor can generate PWM, and that would obviously be a digitally generated source.
Question:	Will this control a heating element
Answer:	it will control the speed of a dc motor within the specified voltage range. It will not reverse the direction of the motor

User questions & answers

Question:	I have a 2 hp 220 volt shunt wound 8 amp dc motor. Will this unit work and if so what resistor should I order
Answer:	In my situation, the unit plugged into the existing hardware system with no problem or modification. If it does not as in your case, I would look carefully at the directions or call the manufacturer.
Question:	I purchased the kbmb 240, controller, which hp resistor do i need for a 180 vdc, 1hp motor? is there a part number for line fuses and reversing switch
Answer:	No it is not. Lowes sells some that are z wave compatible. They are called ZSMOKE and ZCOMBO.
Question:	I have vibration plate zen pro tvr 5910 with 100v-120v, dc motor 1.0hp what plug in horsepower resistor do i need
Answer:	The SA521CN replaces one hard wired unit to provide the wireless connection for add-on wireless units such as the SA500. Example: My alarm system had three hard wired units. Replaced one with the 521. I then added four more units to the system wirelessly with SA500 units. Now have seven interconnected detectors in all without running any additional wires.
Question:	Are the Horse power resistors included? What is the price of the heat sink
Answer:	The BRK wireless smoke detector also has the hard-wire connections to interface with both wired and wireless models. Once installed, two wireless units connected everything together with my non-wireless BRK SC7010Bs in adjacent structures. It was a great solution for my detached garage. With the exception of being wireless, they function in the system like the other BRK models. (Note: Use only compatible models of the same brand) One can call First Alert to check on the compatibility of their various models.

User questions & answers

Question:	How do i wire this for 110? there is an in-n, in-l, out-l, out-n. i connected this on the hot leg to the in-n and out-n. fan runs but no speed change
Answer:	I used mine for varying the speed of a series wound "universal" motor. A motor with brushes and commutator. It worked to vary the speed. I wired it with the two terminals closest to the heat sink to the 110 the two closest to the variable resistor to the motor.
Question:	Which of the 4 screws are power/ground and in/out? They are not labeled
Answer:	I believe you want to know which terminal is power and neutral. Ground is not connected to any terminal, ground would be connected to the frame of the enclosure. This is an AC device, not DC. If you look on the printed circuit side of the board you will see one wire trace goes directly from one terminal to another terminal and no place else, those are the two neutral terminals. Refer to the diagram for line (input) and load (output) terminals.
Question:	Will this work in a led dimming circuit, between the ac mains and a dim able led driver
Answer:	"...LED's do not work with AC current" That is not true. Yes an LED is a diode and only conducts in one direction but that doesn't mean that it won't light up if hooked to an AC source. It will act like any diode and will only conduct on one half of the AC cycle. The 2 things to be considered are: 1. What is your "dim able led driver"? Is it meant to be driven by standard AC house current? If so, you're good to go. If it's expecting DC, then it might work but will only work with one half of the AC cycle. 2. The LED may produce light that is strobing at 60 cycles since it's off half the time. Not good for lighting. Great for headaches. Bottom line get a standard light dimmer switch.
Question:	Will this work to dim some 500w halogen work lights
Answer:	I think the answer would be "yes" with some constraints. "Yes" in that my experience has been it overheats at half the 2000 watt rating, but 500 watts should be OK. You should read up on halogen bulbs because unlike tungsten filament bulbs, halogens need to be operated at a certain minimum temperature. You should be able to dim them down to about 70% duty cycle as long as you also operate them at 100% for substantial periods at other times. Otherwise, I think you may have some condensation of tungsten on the glass tube surface. But as far as the wattage is concerned, this device should be ok t 500 watts. If you exceed its capacity it will have thermal shut down until it cools off. You won't have a huge investment if you decide to try it -- either in the PWM device or the tungsten bulbs. Just make sure you don't go below 70% duty cycle and check the bulb surface from time to time for evidence of metal deposits (silvering) and run at 100% duty cycle for a time to remove it. Good luck.

User questions & answers

Question:	will this work on a chop saw to slow the rpm's for metal blade
Answer:	I believe you could use a non contact tachometer to get the actual RPM that you want then write down the digital number to get that specific RPM afterwards. I have never tested mine in that way but mine seems to be very consistent just eyeballing it and using a timer https://www.amazon.com/Digital-Photo-Laser-Tachometer-Contact/dp/B001N4QY66
Question:	Will this work on a wood lathe
Answer:	Depends on the input circuitry. If it has regulation, it would probably just see a different average or RMS voltage. If not, the u it probably wouldn't work well.
Question:	Could this be used to dim a 500 watt halogen bulb
Answer:	Switch and pot come with it. Just hook up motor and power source and you're in business. Diagram on the case. ALWAYS be sure you get the power polarity right!!!.....most boards of this type will be immediately fried if you switch + and - leads. Works great. No reverse, but you can google dpdt switch reverse motor and easily find a diagram that will show you how to simply wire in a dpdt switch and have reverse if you want it. Instructibles has a nice instruction if you need it.

User questions & answers

Question:	Can i use this control to vary the speed of this old industrial fan? photos: https://ibb.co/qjgwmqc https://ibb.co/pt3fwtq https://ibb.co/d4hbddk
Answer:	Idk about that one!!! I’m thinking it is brushless, so possibly not. It is a brush compatible control, like most power tools use. I use mine on a large landscape pump. Perhaps a brushless compatible control would work - like is used for fan motors.
Question:	can this be used with a Ryobi corded drill
Answer:	Maybe, I’ve used it successfully on my 14” band saw that has a 3/4 hp motor. Does not work on capacitor start motors.
Question:	Do i need two variable fan/router speed controller for this tent. one to bring in fresh air and the other one to filter the air out of the tent
Answer:	I'm assuming your electric nail drill is a hand held device. In that case, yes this will work. It works with any motor that doesn't have a separate starter circuit
Question:	Can I use this to control the speed of a sewing machine motor for a rod wrap set up? Thanks
Answer:	Yes, it works on a 41/2 in grinder very well which pulls more amperage than a jig saw. I se it for slower speeds when polishing stones with diamond wheels. Slower speeds important.

User questions & answers

Question:	What is the lowest ms pulse this will generate
Answer:	The only difference between the two , is the voice alert. First Alert AC Hardwired Voice Alert Carbon Monoxide Alarm and Smoke Detector with Battery Back-Up . The SC7019B does not have the voice alert ; but everything else. They each have the same wire connect. Just remember the letters have a code meaning. S-smoke, C-carbon , B- battery back -up, V- voice alert.
Question:	What size hole is needed to mount the forward reverse switch
Answer:	In this hardwired design, they are interconnected to each other on your 120 volt house wiring system -- typically 14/3 Romex with ground -- black for power, white for neutral and red for the orange interconnection wire. The uninsulated bare ground wire is not used. This First Alert version does not use wi-fi or radio frequencies to talk to each other. Only the unit initiating the alarm speaks the programmed room name. The other interconnected units do not announce the room name; they only sound the alarm. It seems a little misleading to me from the First Alert description. I replaced 11 old units that were interconnected in my house with this design, and when one goes off, I have to run around the house listening for the unit speaking its room name to find the one that initiated the alarm.
Question:	Does it have a Soft start delay if left at 100% duty cycle, & power is turned on/off by separate power source
Answer:	In this hardwired design, only the one initiating the alarm speaks the programmed room name. The other interconnected units do not announce the room name; they only sound the alarm. It seems a little misleading to me from the First Alert description. I replaced 11 old units that were interconnected in my house with this design, and when one goes off, I have to run around the house listening for the unit speaking its room name to find the one that initiated the alarm.
Question:	i the toggle switch on a relay so the wire can be 100' or does all amps go through it? thus more awg ? we run a 8amp motor
Answer:	Only the one initiating the alarm speaks the programmed room name. The other interconnected units do not announce the room name; they only sound the alarm. It seems dumb, but I replaced 11 old units in my house with this design, and when one goes off, I have to run around the house listening for the unit speaking its room name to find the one that initiated the alarm.

User questions & answers

Question:	I have a 1/2HP Leeson motor I need to slow down. Will this work for it
Answer:	Definitely not. This controller is made to control the speed of low current exhaust fans.
Question:	How can you know the actual rpm your motor is turning with this
Answer:	Irregardless of the type of fan, as long as it runs on standard 110Volt it should work. I am using it on me ceiling’s fan which plugs right into a 110V socket. I got it so I can control my 3speed fan more precisely. Works well for me.
Question:	Can I use this to control Pond Pump 10000 GPH, 15A 110V
Answer:	There are no markings nor label to indicate country of origin but given the very low price, I would say it's a safe bet that it was made in China. Wherever it was manufactured, it works well and controlled my exhaust fan very well.
Question:	Why does the horse power of the motor matter? I want to use this with a 15 amp miter saw, but the manufacturer doesn't give a horse power rating
Answer:	There is no cord accompanying the device. It has the standard 110v male and female plugs. I plugged the male into the wall plug and my fan's cord into the female plug in the device. It is an excellent product and I can recommend totally.
