Time Mark Three-Phase Voltage Monitors

 

Models 258 and 269 three phase voltage monitors continuously monitor three phase power lines for phase loss, phase reversal, and low voltage. The Model 269 3 phase monitor also monitors for high voltage. Models 258 and 269 3 phase voltage monitors do not require a neutral connection and can be used with any Wye or Delta systems as part of a HVAC application or building automation systems, BAS. When correct voltage and phase rotation are applied, the internal relay will energize. A fault condition will de-energize the relay. When the fault is corrected, the monitor will automatically reset.
