Output current: 10A MAX, if over 6A please strengthen heat dissipation. (Related to the input and output voltage difference, the larger the voltage difference is, the smaller the output current is)
Constant current range: 0.2-8A
Output power = input voltage * 10A, for example: input 12V * 5A= 60W, input 24V * 5A = 120W, input 36V * 5A = 180W, input 48V * 5A= 240W If you need more power, you can use two modules in parallel, such as the output of 10A, which can be connected in parallel with two modules, transfer the current of each module to 5A.
Working temperature: -40 - +85℃ (please strengthen the heat dissipation when the ambient temperature is too high)
Work frequency: 150KHz
Conversion efficiency: maximum 96% (efficiency is related to input/output voltage, current, voltage difference)
Over-current protection: yes (if more than 13A, it will automatic reduce the output voltage, a certain range of errors)
Input reverse connection protection: yes, (less than 5A if you need more reverse connection current in the input string)
Install mode: 4 3mm screw holes
Connection mode: wiring output
Module size: 69 x 35mm
The adjustment method of output voltage/current:
1. Adjust the RV1 potentiometer according to your battery or LED, set the output voltage you need. For example, 10 series of LED voltage adjust 37V.
2. Turn the RV2 potentiometer around 30 times clockwise, and set the the minimum output current, connect the LED, and adjust the RV2 potentiometer to set the current you need.
Note: please do not adjust the current in the short circuit, the circuit structure of the boost module cannot be adjusted in the short circuit.
Application scope:
1. Make a stable power supply, input 12V, and output can be adjustable 12-50v.
2. Power supply for your electronic equipment, can set output value according to your system voltage.
3. Power supply for your laptop, PDA or various digital products as the on-board power supply.
4. DIY a large power laptop mobile power supply with a large lithium battery pack of 12V capacity, let your laptop go wherever it goes.
This module is really good. It has less spikes/noise as compared to other boost modules. 1.5v p-p at 2.6A and 2v p-p at 4.3A. And it is very simple to filter the noise in this module below 200mv p-p. Temp rose to 52 deg C at 2.6A . Tested upto 8A input current and it works well but requires a fan or bigger heatsink for extended use at 8A input.

I use them mainly as powersupply for my LED projects: 12V in 31V out.
When used in parallel, calibrate them carefully !! otherwise they let out the magic smoke.
For this high power project (200 W) I run 4 in parallel with 50 cm thin wire on the output for equalisation of the load.
Very happy customer

Q:
can I use it's car battery 12v dc to convert 24v dc power supply for tpa3116d2 amp bord in full load?
can I use it's car battery 12v dc to convert 24v dc power supply for tpa3116d2 amp bord in full load?
NO, not powerful enough! Let's say you want 2x50W RMS from the Amplifier. Let's say amplifier and power module are both 90% efficient at that power level. So we need 100W ÷ 0.9 ÷ 0.9 = 123.5 Watts. You want to use input voltage of 12V, so that means you need 10.28 Amps input. The maximum current of this module is lower than 10A, so the answer is NO. Also, for audio you need higher current for music leaks, so when using a boost module you also need to add large storage capacitors (e.g. 10,000 uF) to provide that peak current.

My device is supposed to consume 28V 1A. On input, i have 12V and 10A fuse. When i connect the device the fuse burns. Why is this? Can i fix this adjusting RV2?

no you can not. there is no free energy. you can't have 60w source and get 150w. 60w will stay 60w regardless

Q:
How many 3w 700mA leds can be connected in series? if they were like 15 in series and having an output current of 5A... Is it possible to make 5 series of 15 leds in parallel? or just enough for a set of 15.Thanks
quanti led da 3w 700mA si possono collegare in serie? se fossero tipo 15 in serie e avendo una corrente in uscita di 5A... è possibile fare 5 serie da 15 led in parallelo? o basta solo per una serie da 15.Grazie
Tu necessita saber corretamente a tensão de funcionamento e corrente de consumo de cada LED antes, após isto, basta fazer os cálculos. Aviso, se passar de 2A de consumo o Boost vai necessitar de cooler, dobrar a tensão de saída, mais que dobra a corrente de entrada em relação à corrente de saída
You need to know correctly the operating voltage and consumption current of each LED before, after this, just make the calculations. Warning, if it exceeds 2A consumption the Boost will need to cooler, double the output voltage, more than doubles the input current relative to the output current

Q:
Can you suggest to use this board for AC 50 hz or near to it, constant current supply output by adding any other board in series of it, or modifying this board it self.

If the input EXCEEDS my adjusted output voltage level what would happen?
Does it let the input(whatever) easily through its output, or blocks or make its output to zero volt? Thanks.

If anything, the minimum output would be your input voltage. I haven’t received this yet, but with my background in electronics, I would have to say that’s the case. I hope this helps you!☹️
