The DPB and DPC three-phase monitoring relays feature an upgraded switch mode power supply, which provides a wider input voltage range to cover different mains voltages while reducing heat dissipation. The DPB series has an input voltage range of 208 to 480 Vac, while the DPC series has an input voltage range of 208 to 690 Vac. The relays feature an expansive frequency range of 50 to 400 Hz; noise, harmonics and transient filtering; and DIN rail mounting. Three-phase monitoring relays help to protect motors from severe damage that can result from loss of a phase, phase imbalance or phase reversal.
