Category: 3200312645 / 3206312645
Specifications:
Input Voltage: 5-35V
Output Voltage: Continuously adjustable from 1.25 V to 30V
Rated Output Current: 3A
Max. Output Current: 4A depending on load (more than 15W, preferably with a heat sink)
Size: Approx 48 x 24 x 13mm
Indicator Light:
Constant Current: Indicator (red)
Charging: Indicator (red)
Charged Full: Indicator (green)
Applications:
High-power LED constant current drive Lithium battery charger
4V, 6V, 12V, 14V, 24V battery charger
Solar panels and wind turbines
Battery Use:
Make sure of the voltage and current of the battery you need to charge
Adjust the constant voltage potentiometer to make the output voltage same to the charge voltage
Potentiometer Adjustment Direction: Clockwise (increase), counterclockwise (decrease)
Use the multimeter in 10A current scale to measure output short-circuit current, and adjust the current potentiometer to make sure the output current to the expected charging current value
The charge current of transfer lamp is default 0.1 times of the charging current (constant current value)
Connected to the battery and try to charging (for previous 5 steps, module input terminal is connected to power source, output load is NOT connected to batteries)
LED Constant Current Driver Use:
Make sure operating current and Max operating Voltage of the LED you need to drive
Adjust the constant voltage potentiometer to make sure the output Voltage is up to LED Max operating Voltage
Use the multimeter in 10A current scale to measure output short-circuit current, and adjust the current potentiometer to make sure the output current to the expected LED operating current
Join LED, test (For the above 3 steps, module input terminal is connected to power source, output load is NOT connected to LED)
