Module parameters

Module Properties: non-isolated step-down constant current, constant voltage module (CC CV) charging module

Scope: High-power constant current LED driver, battery charger (including ferroelectric), 4V, 6V, 12V, 14V, 24V battery charging, nickel-cadmium nickel-metal hydride batteries (battery) charger, solar panels, wind turbines

:7-35V input voltage, such as requiring higher voltage, please contact me directly

Output voltage: adjustable (1.25-30V)

Output Current: 3A (more than 15W, please install the heat sink)

Constant current range :0-3A (adjustable)

Turn lamp current: constant current value * (0.1), turn the lamp current value with the constant interaction, such as the constant current value of 3A, turn the lamp current is set to constant current of 0.1 times (0.1 * 3A = 0.3A), while the constant current value, when adjusted to 2A, then turn the lamp current constant current of 0.1 times (0.1 * 2A = 0.2A).

Minimum pressure: 2V

Output power: natural cooling 15W, 25W plus heat sink

Conversion efficiency: 90%

Output ripple: 20M

Operating Temperature: Industrial (-40 Celsius to +85 Celsius) (ambient temperature exceeds 40 degrees, lower power use, or to enhance heat dissipation)

Full load temperature rise: 45 Celsius

No-load current: 10mA (12V switch 4.2V)

Load regulation: ± 1%

Voltage regulation: ± 0.5%

Constant accuracy and temperature: the actual test, the module temperature changes from 20 degrees to 100 degrees, less than 1% change constant value (constant value 1A)

Dynamic response speed: 5% 200uS

Potentiometer adjustment direction: clockwise (increase), counterclockwise (decrease) close to the input of the potentiometer for the voltage regulator (CV), close to the output of the potentiometer to regulate current (CC)

Light: two-color LED charging indicator light red, light green fully charged (do not take the load of green)

Output Short Circuit Protection:

Input Reverse Polarity Protection: Yes

Output to prevent reflux: Yes, the output has an internal series a diode to prevent reflux.

Connection: Welding, plus pin can be directly soldered to a PCB

Optional pins, radiator, shell.

 

          

 

 

 

 

 Battery use:

1 Make sure you need to recharge the battery float voltage and charge current, the module input voltage;

2 adjustable constant voltage potentiometer, the output voltage to 5V or so.

3. 10A current with a multimeter measuring the output short-circuit current block, and adjust the constant current potentiometer allows the output current reaches a predetermined charge current value;

4 adjustable potentiometer allows the output voltage reaches the constant float voltage;

5 connected to the battery, try charging.

(1,2,3,4 take steps to block input power, output load does not take batteries.)

LED constant current driver to use:

1 Make sure you need to drive the LED current and the maximum operating voltage;

2 adjustable constant voltage potentiometer, the output voltage to 5V or so.

3. 10A current with a multimeter measuring the output short-circuit current block, and adjust the constant current potentiometer allows the output current to achieve the desired LED current;

4 adjustable potentiometer allows the output voltage constant pressure to achieve maximum operating voltage LED;

5 connected to the LED, the test machine.

(1,2,3,4 take steps to block input power, output load is not connected LED lights.)
