منبع تغذیه و رگولاتور قابل تنظیم همراه با نمایشگر جریان و ولتاژ

This module is adjustable step-down module, the module can be adjusted above sinking blue adjustable resistance to change the output voltage. Input and output pressure of 1V, 0.8V minimum output voltage can be.

indicated module above IN- (input negative), IN + (positive input), OUT- (output negative), OUT + (positive output) must then correct, otherwise may cause damage to the module.

battery recharging methods: 
1. Make sure you need to recharge battery float voltage and charge current, input voltage of the module; 
2. Adjust the constant voltage potentiometer, the output voltage is regulated to about 5V. 
3. 10A current with a multimeter measuring the output short-circuit current block, while adjusting the constant current potentiometer allows the output current reaches a predetermined charge current value; 
4. turn lamp current default shipping charge is 0.1 times the charging current (current value). 
5. Adjust the constant voltage potentiometer allows the output voltage reaches the float voltage; 
6. connected to the battery, try charging. 
(1,2,3,4,5 step for the module connected to the power supply input, output load is not connected to the battery.)

LED constant current driver Usage: 
1. Make sure you need to drive LED current and the maximum operating voltage; 
2. Adjust the constant voltage potentiometer, the output voltage is regulated to about 5V. 
3. 10A current with a multimeter measuring the output short-circuit current block, while adjusting the constant current potentiometer allows the output current reaches a predetermined LED working current; 
4. Adjust the constant voltage potentiometer allows the output voltage reaches the LED maximum working voltage; 
5. connected to the LED, test machine. 
(1,2,3,4 take steps to block input power, output load is not connected LED.)

Communication Protocol Description: 
1. The module has the computer communication function. Computer module can be easily read current and voltage data,
2. As the module output is TTL level, to achieve and computer communications, but also to the level conversion back to the computer to recognize the RS232 level, need to use this cp2102 usb to TTL module to achieve the conversion.
3. Communication protocol as follows:
Baud Rate: 9600 Bps
BB CC ADDR 00 XX XX CRC (current return command)
BB CC ADDR 01 XX XX CRC (voltage returns to the command)
among them
BB CC for the header (2 bytes)
ADDR for the module address (1 byte)
00 for the read current command (1 byte)
01 to read the voltage command (1 byte)
XX XX arbitrary value (2 bytes)
CRC CRC checksum (1 byte)
