Product Description：
Module parameter:
Input voltage: 4-35V
Output voltage: 1.25-25V continuously adjustable (default delivery voltage 4.2V current 1A, need it
Its voltage can be adjusted by itself)
Adjustment mode: first connect the input power supply (between 4-35V) and then use the multimeter to monitor the output voltage and adjust the potentiometer (usually turn the booster clockwise, reverse the buck)
Output current: 12V to 5V maximum 2A (output other voltage, calculate current by 15W, formula 15 / output voltage = output current)
Output power: up to 15W (if the temperature is high, please strengthen the heat)
Conversion efficiency: 80% (the higher the output voltage, the higher the efficiency)
Operating temperature: industrial grade (-40 ° C to +85 ° C ambient temperature over 40 degrees, please lower
Power use, or enhance heat dissipation)
Full load temperature rise: 45 ° C
Module size: length 50* width 37* height 13 (MM)
Turning lamp current: constant current value * (1% – 100%), the lamp current is linked with the constant current value, for example, the constant current value is 3A, and the lamp current is set to 0.1 times of the constant current (0.1*3A=0.3A) When the constant current value is adjusted to 2A, the lamp current is 0.1 times of the constant current (0.1*2A=0.2A). The default shipment has been adjusted to 0.1 times.
Indicator light: The constant current indicator is red, the charging indicator is red, and the charging is completed.
Output short circuit protection: Yes, constant current (current setting constant current value)
Wiring method: can be directly soldered on the PCB
Scope of application:
1) LED constant current drive.
2) Lithium battery charging (including ferroelectric), 4V, 6V, 12V, 14V, 24V battery charging, nickel-cadmium nickel-hydrogen battery (battery pack) charging.
3) Solar panel, vehicle regulated power supply, etc. Automatic buck-boost voltage regulator circuit.
Battery charging How to use:
1. Determine the float voltage and charge current of the rechargeable battery you need, the input voltage of the module;
2. Adjust the constant voltage positioner and adjust the output voltage to about 3V.
3. Use the multimeter 10A current block to measure the output short-circuit current, and adjust the constant current potentiometer to make the output current reach the predetermined charging current value;
4. The charge-to-light current defaults to 0.1 times the charge current (constant current value). If you need to adjust, please adjust the turn-on current potentiometer; (normally no adjustment)
5. Adjust the constant voltage position device to make the output voltage reach the float voltage;
6. Connect the battery and try to charge.
(1, 2, 3, 4, 5 steps are the module input power supply, the output is not connected to the battery.)
LED constant current drive How to use:
1. Determine the operating current and maximum operating voltage at which you need to drive the LEDs;
2. Adjust the constant voltage positioner and adjust the output voltage to about 3V.
3. Use the multimeter 10A current block to measure the output short-circuit current, and adjust the constant current potentiometer to make the output current reach the predetermined LED operating current;
4. Adjust the constant voltage position device to make the output voltage reach the maximum working voltage of the LED;
5. Connect the LED and test the machine.
(1, 2, 3, 4 steps are connected to the power supply of the module, and the output is not connected to the LED light.
