48V to 12V 20A Programable DC-DC converter with Battery Charger Function



More Information

Very few Step Down DC converter is built with programmable control and LED display which shows voltage , current , operaion mode , and Error Code during protection. A MCU control DC converter with 3 digit LED display , user defined output voltage from 12V to 15V in 0.2V step and the remote voltage sensing designed for voltage sensitive devises .It can be programmed into to a 2 stage battery charger. Its remote control terminal allows for auto or manual On Off operation. It is bundled with remote alarm port for low input voltage (<42V) , 7 fail-save protection all self recoverable.

Digitally adjustable 0.2 V step of output voltage (12V-15V DC) makes it ideal for voltage sensitive devices.

2 stage Battery Charger mode with 14.3V Bulk and 13.6V Float charge.

3 digit LED display for Voltage, Current, Operation Mode and Protection/ Fault Diagnosis.
