The CND310 series Electricity Special UPS system consisting of system cabinet, DBW bypass stabilized cabinet, and PDU feeder cabinet; CONSNANT designs exclusively for power plant, transformer substation, and distribution substation according to the development requirement of China Power. It possesses on-line double conversion and zero transfer function. It can be mainly applied for power system telemechanics, PTU, power line carrier, power system monitoring and so on. After being isolated and filtered by regulator, Single-phase 220V or three-phase 380V can provide stable power for load through inverter when the AC is normal. If the failure of AC power grid supply or a power cut occurs, the backup of DC power system can invert to supply electricity through the reverse diode. If the DC Power System is under voltage or cut off, the static switch will turn to bypass automatically. When the AC power is recover, the static switch will turn to AC power automatically. If the inverter is overloaded or fault, the system will turn to bypass and indicates a warning signal at the same time.
