Warm prompt:Most of our module only provides description introduction or send information, no technical advisory support, beginners, please take carefully.

uThis module is adjustable step-down module, can adjust the module above the blue star output voltage adjustable resistance to change.Input and output pressure difference is 1 V, small can output voltage of 0.8 V.

uModule indicated above IN - (input), + (input), IN the OUT - (output), the OUT + (output) must be correct, otherwise may cause damage of module.

uBattery charging method of use:1. Make sure you need to recharge battery float charging voltage and charging current, input voltage module;2. Adjust the constant-voltage potentiometer, the output voltage regulation to around 5 v.3. The output short circuit current is measured with a multimeter 10 a current block, and regulate the flow of constant potentiometer output current reaches a predetermined charging current value;4. The lamp current charging the default delivery is 0.1 times the charging current (constant current value).5. Adjust the constant-voltage potentiometer to output voltage float charging voltage;6. Battery is connected, try to charge.(1, 2, 3, 4, 5 steps for input power management module, the output light batteries!)

uLED constant current drive method of use:1. Make sure you need to drive the LED working current and working voltage;2. Adjust the constant-voltage potentiometer, the output voltage regulation to around 5 v.3. The output short circuit current is measured with a multimeter 10 a current block, and regulate the flow of constant potentiometer output current to the expected LED working current;4. Adjust the constant-voltage potentiometer to output voltage LED working voltage;5. Plug in the LED, commissioning.(1, 2, 3, 4 steps for input power management module, the output light leds!)
