GF4147数据手册UTC中文资料规格书

描述 Description

The UTC GF4147 is a low-power Ground Fault Interruptercontroller for detecting hazardous current paths to ground andground-to-neutral faults. The UTC GF4147 application circuitopens the load contacts before a harmful shock occurs.The UTC GF4147 circuitry has a built-in rectifier and shuntregulator that operates with a low quiescent current. The low-V OSoffset-sense amplifier allows direct coupling of the sense coil tothe amplifier’s feedback signal. This eliminates the large 50/60HzAC-coupling capacitor.
