    High performance FR4 epoxy sheet used in UPS

    An uninterruptible power supply, also uninterruptible power source, UPS or battery/flywheel backup, is an electrical apparatus that provides emergency power to a load when the input power source, typically mains power, fails. A UPS differs from an auxiliary or emergency power system or standby generator in that it will provide near-instantaneous protection from input power interruptions, by supplying energy stored in batteries, supercapacitors, or flywheels. The on-battery runtime of most uninterruptible power sources is relatively short (only a few minutes) but sufficient to start a standby power source or properly shut down the protected equipment.

    UPS are divided into:prepared UPS ,Online UPS,On line interactive UPS,The working principle of UPS is use the AC to charge the battery.than use the battery to supply the power for inverter cabinet,in order to supply power automaticly when the AC fails.

    GPO-3 sheet,PC are mainly used as Protective cover sheet , the structures plate,battery box which will improve the safety and durability of UPS.
