- This module power output is affect by the
module itself-capacity and pre-and post-class load and other factors; the
following data for professional equipment measured results, without
considering other factors.
Power supply module is a kind of electronic components, please don't buy the
item if you have no electronic expertise.
This Module Properties: It is non-isolated step-down constant current,
constant voltage module (CC CV) charging module
Specification:
- Input Voltage :4-35V
- Output voltage: Continuously
adjustable(1.25-25V unload adjust)
- Output current: 3A Max(If more than 15W,
please install the heat sink)
- CC range :0-2A (adjustable)
- Revolving light current: CC value *
(1%-100%), default is 0.1 times
- Minimum voltage difference: 2V
- Output power: natural cooling 15W

constant current.
- Connect method: Can solder on the PCB with
wire directly
- Input: IN+ input Positive is, IN- input
negative
- Output: OUT+ output is positive, OUT-
output negative

Some
Applications:
- High-power LED constant current driver.
- Lithium batteries (including
ferroelectric), 4V, 6V, 12V, 14V, 24V battery charging, nickel-cadmium
nickel-metal hydride batteries (battery) charge.
- Solar panels, wind generator voltage
regulator circuit board power supply, such as automatic buck regulator
circuit.
Battery use:
- Make sure of the voltage and current of
the battery you need to charge
- Adjust the constant voltage potentiometer
to make sure the output Voltage is about 5V(about).
- 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)
- Adjust the constant voltage potentiometer
to make sure the output Voltage is up to floating Voltage.
- 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 5V(about).
- 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.
- Adjust the constant voltage potentiometer
to make sure the output Voltage is up to LED Max operating Voltage.
- Join LED, test (For the above 3 steps,
module input terminal is connected to power source, output load is NOT
connected to LED).
