DC-DC 400W DC 10V-60V High-Power Step down Buck Converter Constant Voltage Constant Current Adjustable Power Supply Module

Main features of the power module:

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

* Output constant voltage and constant current, the voltage and current are continuously adjustable. Can meet most electrical equipment.

*Large output power, good ventilation and natural heat dissipation 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. The efficiency of the output voltage above 10V is as high as 92%-96%.

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

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

Module parameters：

Module name: 400w step-down constant voltage 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, multiply the IN input by 0.8)

Output low voltage: 0V (+1V)

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

Output constant current: 0.2-15A (continuously adjustable, more than 12A to strengthen heat dissipation)

Output power: 400W (need to add a fan to the heat sink and magnetic ring for forced cooling)

Continuous working power: 280W (in a ventilated environment)

Continuous working current: 12A (in a ventilated environment)

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

Input overvoltage protection: none (overvoltage prohibited)

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

Working frequency: 100KHz

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

Short circuit protection: yes (constant current protection)

Input reverse connection protection: yes (short circuit needs to be careful input reverse connection will burn the input fuse,)

Output anti-recharge: no (charge the battery, the output is connected to an inductive load, such as a motor must be connected to an anti-return diode)

Work indicator: yes (blue LED light)

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

Wiring method: comes with solder-free 25A terminals

Module size: length 60 width 60mm height 45mm

Net weight: 170 grams. Plus packaging 180 grams.

Packaging: independent carton packaging.

Wiring: "IN/IN" is the input. "Output/OUT" is output (with Chinese mark)

Precautions:

* Input and output positive and negative connections are strictly prohibited (input reverse connection will burn the fuse, output reverse connection will damage the control board, the damage to the small board cannot be repaired, it can only be replaced

*The control board is a little rainproof glue, if it is damaged, it can only be replaced. Mind taking carefully

* When charging the battery, when the output is connected to an inductive load, an anti-return diode should be added to the output.
