Product features: uModule USES imported high qualityChip, high efficiency,95%), at the same time, calorific value is small, can go to the 5 a current, at the same time cooperate with original TI op-amp control output current, make the overall output is very stable. uThis module USES lowESROriginal sanyo filter capacitance, can make low voltage ripple to 50mV! uThis module USES SMT machine, reflow soldering, at the same time, each module after two hours of aging test before shipment, to ensure high reliability. |
Warm prompt:Most of our module only provides description introduction or send information, no technical advisory support, beginners, please take carefully.
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!)
