Three-Phase Monitoring Relays
February 1, 2007
Series DPB71 is constructed in a compact housing that snaps onto DIN rail. It can monitor for over- and under-voltage, phase sequence and phase loss situations on three-phase and three-phase-plus-neutral systems. It is provided in two ranges: 177 to 275 VAC and 323 to 550 VAC. Series DPC01 is a True RMS monitoring device for over- and under-voltage, phase sequence, phase loss and asymmetry on three-phase and three-phase-plus-neutral systems. It is capable of monitoring 50 to 60 Hz and offered in 50 to 400 Hz versions. It is available in ranges from 115 VAC delta voltage through 690 VAC delta or star voltage.
