The CARLO GAVAZZI PPB01CM44 is a high-performance true RMS 3-phase voltage monitoring relay designed for precise electrical system supervision. Manufactured in Italy, this relay provides reliable detection of phase loss, incorrect phase sequence, overvoltage, and undervoltage conditions across a wide input voltage range.
Key Features:
Wide input voltage range: from 208VAC to 480VAC ±15% (177VAC to 552VAC) with operation up to 400Hz mains frequency.
Adjustable voltage detection: 8 selectable voltage ranges with over/under voltage thresholds adjustable from + or - 2% to 22% of the selected range.
Switch mode power supply: ensures low consumption, minimal heat dissipation, and immunity to mains disturbances, noise, and harmonics.
Visual status indication: yellow LED indicates relay output status; green LED shows power ON status; alarm LED flashes during faults.
Relay contact output: SPDT relay rated at 8A, suitable for remote alarm signaling and control.
Delay on alarm: adjustable from 0.1 to 30 seconds to filter transient conditions.
Enclosure options: DIN rail mounting (DPB01) and Plug-In version (PPB01) compatible with undecal socket.
