Programmable DC-DC Converter with battery charger function



More Information

This new series of non-isolated digital DC-DC Step Down Converter with micro-processor control for fine adjustment of output voltage to optimally suit the loading condition. The 3 digit LED display shows: output voltage, current, operation mode and fault status It is further equipped with 4 special features: 1. A full powered 2 Stage Charger with 14.3V Bulk & 13.6V Float Charge. 2. A Remote Voltage Sensing at load point to ensure accurate output voltage for distant load/ battery to ensure optimal operation. 3. The Remote control terminal that turns on the converter at the same time the Ignition Switch is tuned on. It can be used with other external on-off switch . 4. An independent, separate and always-on output (0.5A 13.8VDC) for essential devices such as security system that requires a permanent dc source. It can also be used for the remote on off switch.
