300W 20A DC-DC Adjustable Buck Converter Step Down Module

It is possible to get changeable output voltage ranges between 1.2V and 36V using the 300W 20A DC-DC Step-down Adjustable Constant Current Module. The module has several current output ranges up to 20 A. It is easy possible to operate high power applications continuously with the heat sink fitted (provided that for continuous high power output you need to use a cooling fan on the heat sink).

Features:

• LED driver with high power.
• Charge from a lithium battery (or a lead accumulator).
• Power source installed on a vehicle.
• System power supply with low voltage.
• Battery charges at 6V, 12V, 14V, and 24V.
• Laptop power supply built-in.
• Provision of controlled electricity.
• System for low-voltage power delivery.

Specifications:

• Output Current: 20A(max.), 15A (suggested)
• Output Voltage: 1.2V to 36V DC
• Efficiency: 95% (24V to 12V, 20A)
• Output Ripple: Less than equal 50mV
• Wiring Method: Terminal
• Short Circuit Protection: Self-recovery (cannot short circuit for long time)

Pinouts:

• VO+: Output positive
• VO-: Output negative
• +IN: Input positive
• -IN: Input negative
• CV: Output voltage adjustment
• CC: Output current adjustment
• EN: Enable, low voltage level shut off output; suspension, high voltage level is effective

Precautions:

• When input and output is common grounded, no-load CV output constant voltage, CC output constant current
• Working Temperature: -10Celsius -75 Celsius
• Designed with 75V/80A large current dual MOS tube
• The buck module has 2 heat sink that could enhance heat dissipation

Uses:

• Widely used in industrial Automation, scientific Research Equipment, LED Lighting, air Purification, civil equipment, solar panel voltage regulator, battery charging wind turbines and so on.
