The ATC Diversified DPR350C is a 3-phase voltage and frequency monitor. It drops its output relay out on phase loss, phase reversal, phase asymmetry, undervoltage, overvoltage, underfrequency and overfrequency and resets once the fault clears.
Input: Self powered: 280-520 V AC line to line, 160-300 V AC line to neutral. Input range: Measuring range 280-600 V AC (L-L, 3-wire), 160-300 V AC (L-N, 4-wire). Trip points: undervoltage 280-600 V AC (L-L, 3-wire) or 160-300 V AC (L-N, 4-wire), programmable; overvoltage 280-600 V AC (L-L, 3-wire) or 160-300 V AC (L-N, 4-wire), programmable; unbalance 5.0-99.9% asymmetry, programmable (2-20% hysteresis). Trip delay: undervoltage 0-99.9 s programmable. Restart: 0-99.9 s programmable (delay on release); 2-99.9 s power-on delay. Reset: automatic or manual (selectable latching).
Output: 2 x 1C SPDT (two relays), 5 A at 250 V AC (NO), 3 A at 250 V AC (NC). Mounting: DIN rail, screw terminals. Indicator: 3-digit LCD; green power LED and a red LED for each relay (on continuously after a trip). Approvals: cULus Listed, Industrial Control Equipment 496Y; CE. It operates from 0 to +50 °C and stores from -20 to +70 °C.
