User questions & answers

Question:	In the instructions it says to use a diode if using for charging, where does the diode go
Answer:	I don't know what application you are talking about, or which instructions your are talking about, but the right diode in between the power supply and the 'in' on the DROK would not hurt. It probably would be a good thing to have one on the 'out' line as well. A diode is a electric check valve that keeps the power going one way, and will the power to reverse and go backwards. I have solar panels, and they each have a diode right in the box on the back of the solar panel. The power comes from the panel, through the diode, to my DROK adjustable converter, 'IN' the DROK - where it is adjusted - 'OUT' the DROK - to the battery it is charging. This makes the DROK a monitor/regulator. If you have any other questions, let me know, describe your application, (power source, and where the power is to be used) You can also use the DROK as a super light dimmer control, or to control the speed of any small motor.
Question:	I need a cheap driver for an 18v, 42w led light. Has anyone used this with a similar or higher output and does it work well at that high an output
Answer:	Yes it should. I haven't used it for an 18v LED but I have used it for multiple 12v LEDs and even a couple 15m 12v LED Strips. It perform quite well. I have used it at 36v for charging my Xiaomi Mijia M365 electric kick scooter for a short period also. The only issue I have come across are the little red button pieces, they tend to slide off the momentary button on the circuit board and become kinda lodged under the plastic case. But I wouldn't hold that against purchasing this item since the functionality isn't degraded because of that.
Question:	Delivered without instructions -- where can a 'user's manual' be found
Answer:	Hi, there is a PDF Instructions on the product page -- Product information -- Technical Specification -- User Manual pdf https://images-na.ssl-images-amazon.com/images/I/C1X8DiomGTS.pdf Hope it could help you.
Question:	Is the usb output fixed or is it adjustable
Answer:	It's not fixed. I had it as high as 13.3 volts in my application of the USB connector. You need to set output to 5v before using any standard usb device.
Question:	Are these marked with model numbers? I would hate to get these and have no clue of each one's model numbers once out of box
Answer:	yes they are , and if you look up number it will give you voltage and current characteristics for the model number

User questions & answers

Question:	What heat sink would you attach for a constant 2.5A load, and how would you attach it
Answer:	I use 12 - 15 volts input and adjust for 3-9 volts out of pcb for couple projects no heatsink was required. Alo notice the two mounting holes are for standoff mounting hardware. I have no heating issues or circiut at all I thought long ago I would used a fan but it is a effiiant circiut vcc+ regultor. I don't know if higher threshold of 25-28 volts input will heat the reulator but at input volts I'm using" theres no heating. I first was introduced to these DC to DC convertor pcb 's as one was givn as a gift to me it resolved a project the current is stable and reliable. Most projects I was using them for had a draw of 1amp or less . Good-luck.
Question:	Is there any datasheet / CAD model that shows mounting hole dimensions and location of the mounting holes
Answer:	None I know of just trace it out with standoff mounted in your project case and use dremel dril bit kit according to thread hole size. Good-luck.
Question:	With open circuit output ie 0 load, what is the input current consumption. In other words what is the quiescent current? Thanks
Answer:	The one I measured was no load 6.26 milliamperes with a 12V input and set to 5V out. About 75mW but that will change depending on both input and output voltage settings. The same part draws about 120mW at 24V in for example.
Question:	Is the output a percentage of the input, or a constant? If I have 20 v in, adjust to 5v out; input goes to 30v will output be 5v or 7.5v
Answer:	5v fixed. BTW, if you replace the trimmer with a 1k resistor, you'll get 5v with minimal possibility for unanticipated adjustment.
Question:	How many amps does this support
Answer:	A standard 7805 is rated at 1.5 amps. You can find the data sheet online.

User questions & answers

Question:	Why the builtin current meter shows in/out currents the same when i am stepping it down from 12v to 5v? hope it didnt waste all (7 x current) watts
Answer:	7 watts is 7 watts current no matter what the voltage is. The “in” current should be the same as the “out” current minus whatever the module uses in the step down process - which is negligible. If you want to limit the current (watts), the other pot will do that.
Question:	Can i charge a 12v car battery with this if i have a laptob cord or computer power supply hooked to it
Answer:	As long as the laptop power supply can output at least 16 volts. A 12v computer power supply hasn't got enough voltage. A car battery needs approx 14v. You can Google the proper charge voltage for your chemistry. This is buck only so the supply voltage must be higher than the desired output voltage. This power supply has no way of knowing when the battery is fully charged. So be careful what you set the output voltage to so as not to over charge the battery. Hope this helps.
Question:	what is the input range of amps for this unit
Answer:	This is a BUCK converter which is a POWER converter capable of about 120W (max). The input current range will be based on the input voltage and the output POWER. Remember P= E x I, or I= P/E. Since the converter is spec'd at about 96% efficient (I'd use 90%), the input current will be the (output power / 0.9) / Input voltage. (Pout / efficiency) / Input voltage. Input voltage MUST be above output voltage, for this converter, about 1.5V. Example: At an output power of 120W (10V @12A maximum output current spec) and an input voltage of 30V, the input current will be I = 120/.9/32 = 4.44 A. This current will be expected for any combination of output voltage and current that totals 120W, as long as the output current of 12A is not exceeded. If you reduce the input voltage, to 12V (about the minimum allowable at 10V output) the input current will be 120/.9/12 = 11.1A. The extra amp is for the 10% loss in the converter. Warning: In actuality the converter would have trouble delivering 10A at 120W output because the current in the switching transistors (MOSFETs) would be high and would dissipate excess heat. Be sure to install a heat sink to control dissipation. Be sure your source can deliver at least 50% above the calculated input current at the power output and input voltage required.

User questions & answers

Question:	if i have a 12v input why am i only getting 2 volts no matter if i turn it clockwise or counter clock wise ?? what am i doing wrong
Answer:	Assuming that you did not get a defective board (Try another one?), you must turn the potentiometer MULTIPLE times. If memory serves me correctly, you turn the pot clockwise to increase the voltage.
Question:	volts but the highest output is 3.21 volts. i have run the pot full ccw to <1 volt, then full cw to max output. is there a min amp required
Answer:	I'm running 12V into mine and was able to dial it in to 5.00V with no load. So no, there shouldn't be any minimum current for stable voltage. Yours might be faulty.
Question:	what is the max Amp input? Will it work with 12V 10A input
Answer:	I'm a mechanical and not electrical engineer but based on my understanding and assuming you're talking about the step DOWN converter - your question doesn't quite make sense. 12 Volt input is obviously fine according to the spec. Based on your set output voltage, and what you have hooked up on the output end, it will draw a set amount of current. So the current it's drawing on the output will determine (and be the same as) what's being drawn through the input. It shouldn't be drawing more than 5A max of current or it's likely to fry the board.
Question:	what value is the potentiometer? I would like to use a different style one
Answer:	The ones on mine are 10-turn 50K ohm. I think as long as the 5k or higher it will just perform a voltage divider and be fine, it just burns more current at 5k than 20k or 50k... Figure 30v regulated output will be 0.6mA on 50k or 6mA on 5k.
