Uninterruptible power supply (UPS)

UPS is the uninterruptible power supply, is connected to the battery and the host, through the host inverter and other modules of the circuit will direct current into power system equipment. When the power supply is normal, UPS supplies the power supply to the load after the power supply is stabilized. At this time, UPS is an alternating current voltage regulator and it also charges the battery inside the machine. When the power supply is interrupted (accident blackout), UPS will immediately battery dc power, through the inverter switching conversion method to continue to supply 220V ac to the load, so that the load to maintain normal work and protect the load software and hardware from damage. UPS equipment usually provides protection against high or low voltages. The flame retardant requirements for insulation materials are V0, high strength, temperature resistance and other characteristics. Commonly used GPO3
