User questions & answers

Question:	Are these power converters regulated output? if input voltage drops will output voltage stay consistent
Answer:	The output voltage will not change if the input power is sufficient
Question:	Someone answered that to change the output voltage you adjust the potentiometer, but I don't see how to do that from the pictures
Answer:	There is a small pot and is easy to adjust
Question:	Can this be used as a step down converter by running it in rverse
Answer:	No you cannot run this reversed. If you do it can burn! All you can do is apply input voltage, say you applied at the input 12 volts you can increase your voltage at the out terminal by turning the potentiometer from about 9 volts to 45 volts. So it reduces first and then goes on increasing.

Question:	Does this boost converter have any sort of input or output reverse protection; current protection; short circuit protection, or otherwise
Answer:	no,not have
Question:	Can these power supplies keep a constant output when the input voltage varies above and below the output
Answer:	As the previous answer indicated, these are boost only. This means that the input voltage must always be less than the output voltage. If you are interested in a power source that can keep a constant voltage with higher or lower voltage then the output, you can search Amazon for buck/boost converters. Their are quite a few available to cover most needs.
Question:	what would the maximum output of these be, say could they do 36v at 3.5 amps
Answer:	Listing spec says 4 amps and 35V out max.. You dont want to push the max on things typically. My educated guess is that it depends on the input voltage and I would cap the input current at 4A max . Think about the power in/out .. This thing doesnt make energy, it converts energy from one voltage to another higher voltage - at the expense of lower output current. At best its 94% efficient so it loses 6% in heat. For example if you needed 25VDC at 3A out , thats 75 watts, plus 4.5W heat loss (75W x 0.06) , so you need 79.5W input. If your input voltage is 12VDC, you need 79.5W of input power so that's 6.6 Amps (79.5W/12) - not likely, plus 4.5Watts of heat is a lot . Lets try an input of 20V , thats 79.5W/20 = 3.975A input ... might work for a while, still putting out 4.5W heat losses. Short of any better specs, I dont think I'd push it past 3A in or out and 60W of total power transfer for a long term solution but you can probably get out more if you have good airflow and its only peaking hard for say 1 or two minutes. Try it, observe temps, watch current input, if it starts running away getting higher and higher input current at same output then you are doomed, but if it fits your needs then its ok for a while at least. These seem to be good units generally, just need to understand the limitations. Also note that these have 50V in/out electrolytic caps. Thats good, some other brands have 35V caps and you need some margin if you are near 35V , its not good design to run at the max.

User questions & answers

Question:	how do i set the max oputput current that i want to set
Answer:	as per this picture adjust the pot. in the top right corner to your requirements....Ted
Question:	what are the 3 potentiometers for and how do I adjust them? What does it mean when the red led light closer to the input light up? Voltage too low
Answer:	The three potentiometers are to allow you to adjust the output voltage set point, the output current limit point and the input under voltage fault point. The red fault light will turn on when the input voltage is below the set under voltage fault point. Under voltage is intended to protect your supply battery by preventing the battery from over discharging. The instructions provided state, "With the input connected, turn the UV (under voltage) pot counter-clockwise until the fault light turns off. It may take up to 30 rotations."

User questions & answers

Question:	Can this be set to always power on in CC mode
Answer:	If you're asking whether the voltage and current reset when the device is powered down, then the answer is no. The device will have the same output when powered back up because voltage and current are adjusted mechanically (w/ a small flathead screwdriver), not digitally, so the "constant" part really does mean constant in the physical sense, as long the supplied voltage and current remain high enough to provide desired output.
Question:	What does opp error mean
Answer:	Dear customer, OPP:Over-power Protection When output power reaches 35W, OPP will be enable. Best regards.
Question:	I need to increase voltage from 11V to 15V, can it do it
Answer:	Yes this will work. This morning I needed to run 2 12V PC fans from a USB 2.0 port. It worked drawing around 400mA.
Question:	How would i use this as a constant voltage supply if i don’t want a constant current supply (eg, i don’t want to accidentally spike the output v
Answer:	For me this has been a marvelously useful device. I power it with the charger "brick" from a retired laptop PC, capable of as much as a couple amps at 25VDC. The specifications don't make it clear, but you independently set the maximum output current and output voltage using the on-board 10-turn pots while monitoring it on the display. For example when charging a lithium-ion battery, its specs might suggest a the maximum charging current of 0.5A and maximum output voltage of 4.2V. So first, you set the open-circuit voltage to 4.2V. Turn the output current to minimum and connect the batery. Assuming the battery is pretty well discharged, when you first connect it you could potentially sink as much as several amps but that would hurt the battery. No problem, you've set the current to minimum (a few mA). When you connect the battery, turn up the current to 0.5A; the voltage will rise as you turn up the current, probably settling around 3.5V. (I am assuming that your power source will easily supply the required power.) As the battery charges, the voltage will gradually increase to 4.2V while the current stays at 0.5A. But once the voltage gets close to 4.2V the current will start to taper off. If left for several hours the voltage will still be at 4.2V but the current will be only a few mA. So the supply acts like constant current, then transitions to constant voltage. I hope this answers your question. I haven't seen any evidence of loss of control over either output voltage or current. FYI it's worthwhile to experiment with the unit connected to an output load resistor first, to get an understanding of which buttons to press to read the desired values. From memory, you can read input voltage and current, temperature of the heat sink in F or C, and output voltage and current. And you can also read output voltage independent of supplying power to the load (i.e. it can act like a voltmeter).

User questions & answers

Question:	i use a AGM battery for camping, would this work for 12v agm battery to 13.5v (16amps
Answer:	agm ? you mean a deep cycle battery ? Im nit certsin. Mine had no spec sheet with it so Im not sure what will kill it or what wont
Question:	Nowhere in the specs does it mention "step up". my application requires 12vdc in and 20vdc out with 3amp. anybody know if this can be done? doug
Answer:	Yes. Description says step up transformer. 12v min input. Max out 80v. 10 amps max adjustable.
Question:	can this boost 24v 6a to 32v 8a
Answer:	No, you can't get more power for "free". 24 volts at 6 amps is 144 watts (24 * 6). 32 volts at 8 amps is 256 watts. This only changes the voltage, so at 32 volts, you'll get about 4.5 amps (144 / 32).
Question:	With 12v input, will i able to adjust the output to 75v? thanks
Answer:	Yes

User questions & answers

Question:	Please explain: "When using battery, switching power supply, solar panel...as input power, it is necessary to decrease the battery protection
Answer:	You should adjust it to turn off the output when the input is 10.5V or less
Question:	I have 11v - 5amps. How many volts/amps can I get out of this
Answer:	About 50W. Watts is Volts times Amps, Amps = Watts/Volts. Example: you want 24V, 50/24=2.08A At 24V output, you can get is ~2.08A output
Question:	can I step up 30v to 48v with 300amp
Answer:	This performs well If you don’t put it to the extreme. Mine works perfectly and perform this job for the last year and it is a recommend
Question:	Can this take 9v dc input and output 14-15v. 20a for 8-10 second bursts? long rest times in between ops. is this a good choice or is there better
Answer:	Not likely with this converter because the input range is 10-60vdc. It’s theoretically possible but only if your 9v source can provide the necessary amperage without voltage drop. It’s more likely to go from a higher voltage source to your 14-15v instead. I would suggest buffering the output 14-15v with super capacitors to achieve your specs.
