Uninterruptible Power Supply (UPS)


UPS that is, uninterruptible power supply, is the battery connected to the host, through the host inverter and other modular circuits will be converted to DC power utility system equipment. When the utility input is normal, the UPS will be the utility voltage regulator supplied to the load, at this time the UPS is an AC voltage regulator, it also charges the battery in the machine; when the utility power interruption (accidental blackout), the UPS will be immediately the battery's DC energy, through the inverter switching conversion method to the load to continue to supply 220V AC power to the load to maintain the normal work and to protect the load software and hardware from damage. UPS equipment can usually provide protection against over-voltage or under-voltage. Flame retardant insulating materials are required to be V0 grade, high strength, temperature resistance and other characteristics required. Commonly used GPO3
