| MODEL 246 3-Phase Monitor |
| Series Description: The Model 246 3-Phase Monitor is designed to continuously monitor 3-phase power lines for abnormal conditions. This device features solid-state voltage and phase angle sensing circuits, which drive a SPDT electromechanical relay. A neutral is not required, allowing the Model 246 to be used with either Wye or Delta systems. Three versions of the Model 246 cover the 120 and 208/240 VAC, 60Hz and the 380 VAC, 50Hz ranges. In addition, the models A246 and B246 are now CSA Certified. Each option on the Model 246 monitor is adjustable throughout its operating range. The adjustment pots and LED indicators of OVER VOLTAGE and UNDER VOLTAGE are mounted on the front of the unit, for easy access. |
