User questions & answers

Question:	Will this work on HF 8” grinder #62501 as a variable speed control? Want to run wire wheel at slower speed to lessen vibration
Answer:	It should. It’s a simple rheostat and handles most high amp greenhouse fans with constant on time.
Question:	can this work on Dremel
Answer:	Should work with fixed speed models. I bought for variable speed Dremel to run it slower. Variable speed Dremel tools must be set to 10 on tool or they won't power on with this controller. Slowest speed on this controller is faster than slowest speed on Dremel when not connected to this controller.
Question:	Is the 8 inch fan strong enough to use in a grow room that is 810 CFM? 9‘ x 9‘ x
Answer:	It is going to replace/evacuate all the air in your grow space every 65 seconds. I cant imagine a scenario where you would need more.
Question:	Can this work for a 1500w 110 volt heating unit
Answer:	The math in the description is a bit inaccurate on this thing. One person correctly points out that it says 15 amps, which works out to 1800 watts. Yet in the product description, it says 1500 watts. Personally, I use this for four 250-watt halogen heating bulbs (so 1000 watts, or about 9 amps), and it works fine for that purpose.

User questions & answers

Question:	Can it be used on a 12volt case fan to slow the speed down
Answer:	Yes! I have a 12v motor on a atv seed spreader, i use it to control the speed of the motor.
Question:	Can this br used with a permanent magnet motor
Answer:	This controls a plain DC motor, a permanent magnet type.
Question:	Is there a way for this to be powered-up in off-state instead of on-state ? can be a hazard otherwise
Answer:	When power is applied, the controller will output voltage that is set by the last used setting. By pushing the rotary voltage adjustment knob the voltage output will be shut down. Push the knob again and preset voltage will be outputted once again.

User questions & answers

Question:	Will this work for a 110v 3/4hp 4.5amp 2500rpm dc motor
Answer:	This is a photo alarm. Your old one was an ion one. Different models respond better to different situations. Best to have both or a combination of both. http://www.nfpa.org/safety-information/for-consumers/fire-and-safety-equipment/smoke-alarms/ionization-vs-photoelectric
Question:	is this for brushless motor or brush
Answer:	This smoke detector is photo-electric not ionizing. Someone else can probably give you a more precise answer but I'd figure it's about the same amount of radiation as the dirt outside.
Question:	How many watts can this handle
Answer:	Dear Mr. Priestley, The detector comes with a mounting bracket and screws with anchors. If you are not mounting the detector into a wooden surface or a wooden stud underneath drywall then you would have to use a sheetrock anchor to mount the receiving bracket for the detector. All of that is provided and once the mounting bracket is secure in the wall or ceiling, simply align the detector tabs with the mounting bracket receivers, press in and give about a 1/4" rotation on the detector and it should hold fast.
Question:	Sirve para los motores de las cintas de correr? arriba dice motores dc. Pero quiero confirmar
Answer:	The alarm works perfectly
