GM1851

UNISONIC TECHNOLOGIES CO., LTD GM1851 LINEAR INTEGRATED CIRCUIT GROUND FAULT INTERRUPTER  DESCRIPTION The UTC GM1851 can specially provide ground fault protection for AC power outlets in consumer and industrial environments. As ground fault currents greater than a presentable threshold value, it will trigger an external SCR-driven circuit breaker to interrupt the AC line and remove the fault condition. Besides of detection of conventional hot wire to ground faults, the neutral fault condition is detected also. In the event that noise pulses introduce unwanted charging currents and a memory circuit that allows firing of even a sluggish breaker on either half-cycle of the line voltage when external full-wave rectification is used, circuitry that rapidly resets the timing capacitor.  FEATURES * Internal power supply shunt regulator * Externally programmable fault current threshold * Externally programmable fault current integration time * Direct interface to SCR * Operates under line reversal; both load vs line and hot vs neutral * Detects neutral line faults  ORDERING INFORMATION Ordering Number Lead Free Halogen Free GM1851L-D08-T GM1851G-D08-T GM1851L-S08-R GM1851G-S08-R Package DIP-8 SOP-8 Packing Tube Tape Reel GM1851G-D08-T (1)Packing Type (2)Package Type (3)Green Package  MARKING DIP-8 (1) T: Tube, R: Tape Reel (2) D08: DIP-8, S08: SOP-8 (3) G: Halogen Free and Lead Free, L: Lead Free SOP-8 www.unisonic.com.tw Copyright © 2019 Unisonic Technolog...
