The new models feature an upgraded switch-mode power supply, which provides a wide input voltage range while reducing heat dissipation and improving reliability and stability. The DPB series has an input voltage range of 208 VAC to 480 VAC, while the DPC series has an input voltage range of 208 VAC to 690 VAC. All new models feature an input frequency range of 50 to 400 Hz, making them suitable for a wide range of applications. Three phase monitoring relays protect motors from severe damage that can result from loss of a phase, phase imbalance, or phase reversal. The units can protect motors used in a wide range of applications, including: HVAC systems, water treatment, material handling, machine tool, marine and aviation. Key features of the monitoring relays include: noise, harmonics, and transient filtering; significant reduction in power consumption versus previous models; wide input voltage and frequency range; voltage ranges selectable by DIP switches; and DIN Rail mounting. A plug-in option is available for the DPB series.
