Input current: 10-30V input voltage, maximum current 30A
31-60V input voltage, maximum current 25A
Static working current: 15mA (12V liters 20V, the higher the output voltage, the quiescent current will increase)
Output voltage: 12-90V continuously adjustable (default output 19V. If you have a multimeter buyer can adjust it)
Output current: 20A MAX , More than 15A, please strengthen the heat dissipation (related to the input and output voltage difference, the larger the differential pressure, the smaller the output current)

Input anti-reverse connection: Yes (150A power MOS anti-reverse)
Low battery protection: With (8-50V adjustable) self-recovery
Working temperature: -40~+85 degrees (enhance heat dissipation when the ambient temperature is too high)
Working frequency: 150KHz

Module size: 130mm x 52mm x 84mm (length x width x height) (high copper column and fan), 130mm x 52mm x 67mm (length x width x height) (high without copper column and fan)
Module single weight: 490 grams
Output power: = input voltage * 30A, such as: input 12V * 30A = 360W The maximum power when inputting 12V is 360W
Input voltage *30A For example: input 24V * 30A = 720W, that is: the maximum power is 720W when inputting 24V
Power Description:
Since the input current is 30A at 10-30V and the input current is 25A at 31-60V, the output power is related to the input voltage. The higher the input voltage, the higher the power.
(Input voltage * input current is equal to the whole machine power) For example, the input 12V*30A power is 360W. The input 24V*30A is 720W. When the input voltage is 36V, the input current is 25A. The maximum power is 900W.
Voltage regulation:
When the power supply is unloaded, use a flat-blade screwdriver to adjust the output terminal "V-ADJ" potentiometer clockwise to increase, counterclockwise to small, due to the large output capacitor capacity, the output voltage is adjusted from high voltage to low voltage. The reaction will be slower. The adjustment of the instrument is smaller. (The default output voltage is adjusted to 19V)
Current regulation:
Adjust the "CC A-ADJ" potentiometer counterclockwise for about 30 turns, set the output current to the minimum, connect the load such as the LED battery, and adjust the "CC A-ADJ" potentiometer clockwise to the current you need. For battery charging, after the battery is discharged, it is connected to the output, and adjust the CC A-ADJ to the current you need. When charging, be sure to use the discharged battery to adjust the battery. The more the charge, the smaller the charge current. The default output is ESC to 3A. (Do not adjust the current by short-circuit output. The circuit structure of the boost module cannot be adjusted by short circuit.)
Input low battery protection adjustment:
The low battery protection is mainly for preventing the battery from being over-discharged when the input power is the battery, the power module and the battery will be damaged if the battery voltage is too low. When the input is the switching power supply, the low voltage protection should also be set.
Method 1: For example, set 12V battery low battery protection. Connect a 10V voltage to the input terminal of the power module. Use a flat-blade screwdriver to adjust RV1 (clockwise protection voltage value is increased, counterclockwise protection voltage is turned down) until the UVLO lamp is on. At this time, the low battery protection voltage is 10V. When the voltage drops to 10V, the power module does not rise (the input voltage is equal to the output voltage). Only after the input voltage is higher than 10V, the power supply starts to resume boosting.
Method 2: Input the battery or switch power supply. If the UVLO lamp on the board is off, adjust the RV1 potentiometer counterclockwise to brighten the UVLO lamp, and then turn it clockwise two turns. If the UVLO lamp is on, turn the RV1 potentiometer clockwise, turn off the UVLO lamp, and then turn it two turns. (Adapt to 8V-45V voltage)

This step-up converter is powerful and versitile. There are two adjustment settings. One for constant voltage and one for constant current. I use this converter on my e-bike together with a 3-phase rectifier that is connected in line with the hub motor cable. This converter is adjusted to 45V output, but with a current limit of 6 Ampére regenerating charging current.
The converter delivers 45V out when the input voltage is as low as 7-8 VDC. The constant current works perfectly. It delivers 6 A out when input voltage varies from 12 - 42 Volt.
The converter was delivered in a thin plastic bag with some stuffing inside. Small dents on the capacitors, but the converter works fine.

Part came significantly damaged and broken.
Bent heatsink, cracked power connections, crush PCB corners and, most significantly, one of the trimable pots and a resistor had been ripped off the board.
Unusable upon delivery. I wouldn't even test it to try and see if it worked for fear of electrocution.
I have requested a refund, which Banggood have agreed to, and will be buying another as I need one for a project. I hope the second time around is better!

Their are 3 MultiTurn TrimPots... You can find the values of them by looking on the top of them... you will see a number similar to 103, *****, etc. those numbers are the value for example 103 is 10,000 Ohm... 301 would be 300 Ohm, 104 would be 100,000 Ohm... You should replace them with "MultiTurn" Potentiometers, if you have the "Skill" to replace them. You can allways carefully take each one out carefully, remembering where you took them out, and Ohm each one out with your meter.. if you do not know how to do this, you are not qualified to do this.

This module works between 10V - 60V DC voltage so you should not give 110v

Q:
I connected the device output to a 14.5 V (16.4 full) Li Ion battery (output) and the input to a solar panel , 30 V . The output was connected last, and immediately caused a spark and smoke. The device still has two diodes with light, but produces no output.. Could this be caused by a solar panel dropping below 10 V input? Is a battery an illegal load to be used (can the device get high reverse currents from the battery)? Which component is likely to be destroyed

I'm looking for a device that connects to a camper 12V battery (so input between 10V-14.7V) and outputs (exactly) 12V as power supply. Will this device help me ?

This is most likely just as it appears. The two (+) are paralleled terminals for multi connections just as the two (-) terminals are. It does not matter at all which you choose to use as long as you keep the polarity correct. To test and prove this use an Ohm meter. You should not get more than about 1 Ohm or less between the two (+) or the two (-). To get the best most accurate reading you should clamp and tighten the meter leads in the terminal as you would a wire.

Is it normal for the inductor to get hot even under low load? I use the converter to step up 24v to 39v at around 5 amps at the input, so just ≈120 watts. Even with a separate fan cooling the inductor it is over 40°C.
