Three-phase monitoring relays with a wider input voltage range

Carlo Gavazzi has launched three-phase monitoring relays, part of its DPB and DPC lines, that feature an upgraded switch mode power supply, which provides a wider input voltage range to cover different mains voltages, while reducing heat dissipation and improving reliability and stability.

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.

All of the new models from Carlo Gavazzi feature a frequency range of 50 to 400 Hz, making them suitable for a wide range of applications.

Three phase monitoring relays are used for protecting motors from severe damage that can result from loss of a phase, phase imbalance, or phase reversal.

Motors can be found in applications such as HVAC systems, water treatment and material handling.
