Description:
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
Conversion efficiency: 80% (the higher the output voltage, the higher the efficiency)
Operating Temperature: Industrial (-40 C to +85 C) (ambient temperature more than 40 C, lower power use, or add heat sink)\
Full load temperature rise: 45 C
Indicator: CC indicator is Red, charging indicator is Red, charging completed the indicator is Blue.
Output short circuit protection: Yes, 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
Module Size: 50 x 37 x 13mm
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).
