Time Mark C269 Power Monitor

The Time Mark C269 Power Monitor continually supervises 480 VAC three-phase power systems for overvoltage, undervoltage, phase loss, and phase reversal to protect motors and industrial equipment from damaging power conditions. Commonly installed in motor control centers, HVAC systems, pumps, compressors, conveyors, and other critical process equipment, it supports Wye or Delta configurations without a neutral connection and uses a solid-state design to monitor high and low voltage conditions with an adjustable trip delay to prevent nuisance shutdowns. Key specs include nominal voltage of 480 VAC (phase-to-phase); voltage adjustment ranges of upper 400–540 VAC and lower 380–460 VAC; 60 Hz operation; 6 W power consumption; SPDT output contacts rated 10 A at 240 VAC resistive; automatic reset with a 0.25 s reset time; repeat accuracy ±0.1% of set point; dead band ~2%; transient protection of 2500 VRMS for 10 ms; mounting as surface mount in ABS plastic enclosure; operating temperature −20°F to +130°F (−29°C to +54°C); UL Listed and CSA Certified. Typical applications include three-phase motor protection in industrial automation, HVAC equipment, pumps, compressors, conveyors, and process machinery, with common replacements Time Mark C269R and Time Mark B269.
