NCS37012:Single CT GFCI with Self-Test
The NCS37012 is a fully UL943 compliant signal processor for GFCI applications with self test. The device integrates a flexible power supply (including both shunt and LDO regulators), differential fault, and grounded-neutral detection circuits. Proprietary impedance measurement and signal processing techniques are used to minimize the number of external components and improve performance. The device also includes a specialized DSP controller that offers best in class immunity to nuisance loads without the need for external analog filters. Self-test is monitored every 17 minutes through an external current path and internally generated grounded neutral fault.
特性
- full self test and trip indicator monitoring
- self syncing internal oscillator adjusts to AC mains frequency to guarantee full resolution on 50 and 50Hz distribution systems
- randomized testing sequence to noise sensitivity and potential interactions on the AC mains
- high SCR drive current (up to 5mA)
