| Datasheet | Download Datasheet |
The TimeMark 18-240-400/SG is a 3-phase monitor for 208/240 V AC, 400 Hz systems. It drops its output relay out on phase loss, phase reversal and undervoltage and resets once the fault clears.
Trip points: undervoltage 160-240 V AC. Adjustment: field adjustable. Trip delay: undervoltage 1-30 s (adjustable). Restart: 1-300 s (adjustable). Reset: automatic.
Output: 1C SPDT (silver with gold flash), 5 A at 120 V AC resistive. Mounting: DIN rail or surface mount. Indicator: "FAULT" (red) and "NORM" (green) condition indicators. Approvals: UL Recognized (U.S. and Canada). It operates from -29 to +55 °C.
