DPR Monitoring Relays

ATC Diversified Electronics DPR Monitoring Relays feature DIN rail mount and Relay ON and Power ON LED indications. These monitoring relays are available in phase and voltage phase classifications. The voltage phase monitoring relay features under-voltage, over-voltage, under-frequency, over-frequency, asymmetry, phase failure, and phase sequence monitoring in the 3Ø system. This voltage phase monitoring relay offers adjustable switching hysteresis, two separate alarm relays, and RMS measurements. The voltage phase monitoring relay operates at a <200ms response time and -20°C to 70°C storage temperature range. This phase monitoring relay offers a slim, space-saving design and a 0.2sec to 10sec Trip delay (T). The phase monitoring relay operates at -20°C to 75°C storage temperature range, 236V to 290V AC over-voltage, and 8VA maximum power consumption.
