* حتما قبل از اتصال به ماژول ولتاژ خروجی را روی 5 ولت تنظیم نمایید
★ 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.)
