CARLO GAVAZZI DPB02CM48 - 3- Phase Phase Sequence/Loss

The Carlo Gavazzi DPB02CM48 monitoring relay is a three-phase monitoring relay used for phase sequence, phase loss and asymmetry with a built-in time delay function.

The DPB02CM48 features a 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 monitoring range of 380 to 480 VAC is covered by two multi-voltage relays.

Connected with the three phases (and neutral), the DPB02CM48 operates when all three phases are present at the same time, the phase sequence is correct and the asymmetry is under the set level. The unit can be customized to each user application by adjustments to over and under voltage, alarm delays, and asymmetry.

Features:

• Detects when all three phases are present and in proper sequence
• Detects if asymmetry level is below the set value
• Measures its own power supply
• Selection of measuring range by DIP switches
• Adjustable asymmetry on a relative scale
• Adjustable delay function (0.1 to 30 seconds)
• 380 to 480 VAC power supply range
• 8A SPDT relay output normally energized
• 22.5mm DIN-rail housing (DIN 50022)
• LED indication for relay, alarm and power supply ON
