DC 400W 15A Stepdown Buck Converter Constant Current Power Supply LED Driver 10.560V To 045V Voltage Charger Step Down Module

Product selling point

1: There is a constant current indicator when charging the battery. The charging status is clear at a glance.

2: The output power is large, the ventilation is good, and the natural heat diipation can achieve 280W/12A (note that there are output power and output current limits).

3: 10-60v wide input voltage, suitable for most power supplies on the market as input source

4: The module adopts a step rectification scheme, which is extremely efficient, and the output voltage is above 10V and the efficiency is as high as 92%-96%.

5: There is input undervoltage protection

Main features of power supply module:

10-60v wide input voltage, suitable for most power supplies on the market as input source.

The output is constant voltage and constant current, and the voltage and current are continuously adjustable. Can meet most of the electrical equipment.

Large output power, good ventilation, natural heat diipation can achieve 280W/12A (note that there are output power and output current limits).

The module adopts the step rectification scheme, which has extremely high efficiency, and the output voltage is above 10V and the efficiency is as high as 92%-96%.

There is a constant current indicator when charging the battery. The charging status is clear at a glance.

The input has a 15A fuse, and the positive and negative poles of the input will not damage the power supply (the fuse will be burned, and the fuse needs to be replaced)

Module

Module name: 400w step-down constant voltage and constant current

Module nature: non-isolated step-down module (BUCK)

Input voltage: 10.5-60V

Output voltage range: 0-45V (must meet the step-down condition, IN input is multiplied by 0.8)

Minimum output voltage: 0V (+1V)

The highest output voltage: approximately equal to the input *0.8 (for example, the input is 40V, 40V*0.8=32V, the highest output voltage is 32V, which will actually be a little higher and reach about 34V.35)

Output constant current: 0.2-15A (continuously adjustable, heat diipation should be strengthened if it exceeds 12A)

Maximum output power: 400W (a fan needs to be added for forced cooling of the heat sink and magnetic ring)

Continuous maximum working power: 280W (under ventilated envment)

Continuous maximum working current: 12A (under ventilated envment)

Input under-voltage protection: Yes, (input is lower than 10.5V to turn off the output, there is an error of about 0.5V)

Input overvoltage protection: none (overvoltage is prohibited)

Working temperature: -10~+85 degrees (enhance heat diipation when it exceeds 65 degrees)

Working frequency: 100KHz

Conversion efficiency: up to 97% (efficiency is related to input, output voltage, current, and preure difference)

Short circuit protection: Yes (constant current protection)

Input reverse connection protection: Yes (please be careful when short-circuiting the input and the input reverse connection will burn the input fuse)

Output anti-recharge: none (to charge the battery, output connect inductive load, for example, anti-reverse diode must be added to the motor)

Work indicator: Yes (blue LED light)

Constant current indicator light: Yes (the CC indicator red light on the small board lights up when the constant current is working, there is no current output, and the light does not light up when the voltage is constant)

Connection method: Comes with welding-free 25A terminal block

Module size: length 60 width 60mm high 45mm

Net weight: 170 grams. 180 grams with packaging.

Packing method: independent carton packaging.

Wiring: "Input/IN" is input. "Output/OUT" is output (marked in Chinese)

Precautions:

It is strictly forbidden to connect the positive and negative poles of the input and output in reverse (reverse input will burn the fuse, and the reverse connection of output will damage the control board. The damage of the small board cannot be repaired and can only be replaced.

The control panel is a little rainproof , if it is damaged, it can only be replaced. Mind shooting carefully

To charge the battery, when the output is connected to an inductive load, the output should be equipped with an anti-reflow diode
