HBC-DFA Series inverter is a highly reliable automatic emergency uninterrupted power supply, uses imported integrated PWM (pulse width modulation) control, high power MOSFET driver. It charges the battery automatically when there is city power, with charging over voltage protection; when electricity outage occurs, it will convert into DC from battery into AC output, ensure no power failure within 24 hours unattended. Has advantages of quick response, anti-lightning, stable voltage and frequency output, high adaptability and practical etc. |
