This is a DC-DC constant current boost converter 1200W 20A CC/CV Boost Converter power supply module with DC 10-60V voltage input and DC 12V-83V output voltage. The input and output of the module are designed with screw terminals for convenient wire connection or disconnection. Besides, it equipped with a big heat sink and cooling fan for better dissipation which can help your project a lot. You can also use the module as a driver for high power LED lights or voltage regulator for solar panels.

Frequency: 150KHz
Conversion Efficiency: 92% to 97% (Efficiency is related to input/output voltage, current and voltage difference. The smaller difference is, the higher efficiency will be)
Input Over-current Protection: Yes (automatically protect when input is more than 25A, and power supply voltage will not increase)
Short Circuit Protection: Yes (input 30A fuse)
Wiring Method: Terminals (Please use large current copper wire)
