Product information:

Model: Power Module
Type: Power Module
Package: Adjustable DC power supply
Lot number: DIY kit
Application field: 3C digital
Product Description: Power Module

Circuit characteristics:
All in-line components, easy to install and maintain;
The output voltage is easy to adjust;
The output current limit status is indicated by LED;
When the output current exceeds the limit current, it will automatically switch to constant current mode, providing complete protection against overload or failure.
The actual product installed using the kit:
The radiator and fan are not included in the kit, and there is an external 24V cooling fan interface on the board. The adjustment tube of this circuit can be operated with load only with a large enough radiator or fan, remember! Otherwise, the adjustment tube will be damaged due to overheating.
The potentiometer can be directly soldered on the board, or it can be led to the panel for installation. The kit is equipped with a connecting socket and a connecting wire
The power transformer selects 24V AC output (or double 12V, the tap is empty, not higher than this voltage), the power can be selected according to needs, if 30V3A output is required, the transformer power must be greater than 90W.
1. Set the voltage adjustment potentiometer to the small position (turn it counterclockwise to small), adjust RV1 (100K adjustable resistance), so that the output voltage is 0V, that is, the large output voltage does not need to be adjusted. Use 24V AC input, yes The maximum output voltage is about 31V
2. Output limit current setting: Determined by the position of the current potentiometer. The picture below shows the 10V voltage and 10 ohm load resistance. Adjust the current potentiometer to make the LED just light up. At this time, the current potentiometer is at the 1A position and the circuit turns to constant current. At this time, adjust the voltage potentiometer, you can see that the voltage will not continue to rise, and the current is maintained at a current limit of 1A
