The UTC GF4147 is a low-power Ground Fault Interrupter controller for detecting hazardous current paths to ground and ground-to-neutral faults. The UTC GF4147 application circuit opens the load contacts before a harmful shock occurs.
The UTC GF4147 circuitry has a built-in rectifier and shunt regulator that operates with a low quiescent current. The low-VOS offset-sense amplifier allows direct coupling of the sense coil to the amplifier’s feedback signal. This eliminates the large 50/60Hz AC-coupling capacitor. GF4147L-AG6-R资料下载
