Uninterruptible Power Supply
UPS is the uninterrupted power supply which is connected to the host by the battery ,converts the direct current into the system equipment of the AC by module circuit of the main engine inverter. When the market input is normal,UPS supplies the AC to the load after voltage stabilization .At this time, UPS is an AC voltage regulator, and it also charges the battery inside the machine;
When mains supply interruption (power outage), UPS use the battery's direct current energy to continue supply 220V alternating current to the load immediately through the inverter switching conversion method ,it makes the load keep working and protect the software and hardware from being damaged. UPS devices usually provide protection against voltage too high or too low .The flame retardant requirement for insulating materials is V0, high strength and temperature resistance , The commonly materials used in UPS is HC-GPO3
