Features:
domestic module LM2596 chip quality, high efficiency (up to 92%), while low heat, can easily currents up to 3A above, in conjunction with the original TI op amp output current control, the overall output is very stable.
This module uses the original Sanyo low ESR capacitor filter, you can make low ripple voltage 50mV!
This module uses machine placement, reflow soldering, and each module before shipment have been two hours of aging tests to ensure high reliability.
This module is an adjustable step-down module that can change the output voltage by adjusting the blue adjustable resistor on the module. Input and output voltage difference of 2V, the minimum output 1.23V voltage.
IN- (input negative), IN + (input positive), OUT- (negative output), OUT + (output positive) must be correct, otherwise the module may be damaged.
battery charging use:
1. Make sure you need to recharge the battery's float voltage and charge current, the module's input voltage;
2. Adjust the constant voltage potentiometer, adjust the output voltage to about 5V.
3. With the multimeter 10A current block measurement output short-circuit current, while adjusting the constant current potentiometer so that the output current reaches a predetermined charge current value;
4. Charging Turn the lamp current default shipment of 0.1 times the charge current (constant current value), if you need to adjust the adjustment of the lamp current potentiometer; (generally do not adjust)
5. Adjust the constant voltage potentiometer so that the output voltage reaches the float voltage;
6. Connect the battery, try charging.
(1, 2, 3, 4, 5 steps for the module input power supply, the output does not load the battery.)
LED constant current drive use:
1. Make sure you need to drive the LED's operating current and the maximum operating voltage;
2. Adjust the constant voltage potentiometer, adjust the output voltage to about 5V.
3. With the multimeter 10A current block measurement output short-circuit current, while adjusting the constant current potentiometer so that the output current to a predetermined LED operating current;
4. Adjust the constant voltage potentiometer to make the output voltage to LED maximum operating voltage;
5. Connect the LED, test machine.
(1, 2, 3, 4 steps for the module input power supply, the output no load LED lights.)
