- This modules use high-quality imported chips, high efficiency (up to 95%), low heat, and it can up to 5A maximum current, in conjunction with the TI op amp control the output current, the overall output is very stable.This module uses the Sanyo low ESR filter capacitor,the ripple voltage as low as 50mV!
- This module is adjustable buck module, you can adjust the blue adjustable resistoron the module to change the output voltage. The input must be higher than the output about 1V. The minimum output voltage can be 0.8V.
- 1 Make sure you need to charge the battery float voltage and charging current, the input voltage of the module;
- 2 Adjust constant potentiometer, the output voltage is regulated to about 5V.
- 3 Use a multimeter of 10A current to measure the output current of short-circuit current block, while adjusting the constant current potentiometer to make the output current reaches charging current value;
- 4 The charging turn lamp current\'s default is 0.1 times of the charging current (constant value)
- 5 Adjusting the constant voltage potentiometer to make the output voltage reaches the float voltage;
- 6 connected to the battery, try to charge.
- (1,2,3,4,5 step for powering the module input, the output load do not need to connected to the battery.)
- 1 Make sure the LED drive operating current and maximum operating voltage you need;
- 2 Adjust constant potentiometer, the output voltage is regulated to about 5V.
- 3 Use a multimeter of 10A current to measure the output current of short-circuit current block, while adjusting the constant current potentiometer to make the output current reaches LED operating current value;
- 4 Adjusting the constant voltage potentiometer to make the output voltage reaches the float voltage;
- 5 connected to the battery, try to operate.
- (1,2,3,4 step for powering the module input, the output load do not need to connected to the LED.)
- 1 This module has the computer communication function. Computer can be easily read data of the module\'s current and voltage,
- 2 As the module output is TTL level, if you want to achieve the communication withcomputer, you need to change the TTL level to the RS232 level which can be recognized by computer.
- 3 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
- BB CC for the header (2 bytes)
- ADDR for the module address (1 byte)
- 00 to read the current command (1 byte)
- 01 is a read voltage command (1 byte)
- XX XX arbitrary value (2 bytes)
- CRC CRC checksum (1 byte)
- 1 x DC Boost Power Module + 2in1 Volt Amp Panel Meter
