PVMD-G

The EAPL PVMD-G is a high-precision phase voltage monitoring device designed to protect three-phase systems from over-voltage, under-voltage, phase reversal, phase loss, and voltage unbalance. It continuously monitors the incoming three-phase supply and isolates the load instantly whenever voltage or phase conditions fall outside the safe limits. Compact, intelligent, and dependable, the PVMD-G provides complete protection for motors, compressors, and electrical panels in industrial and commercial installations.

Key Features:

• Monitors over-voltage, under-voltage, phase failure, phase reversal, and voltage imbalance conditions.

• Adjustable upper and lower voltage trip limits for precise protection.

• Delay-on and delay-off timers to prevent nuisance tripping from transient fluctuations.

• LED indicators for Power ON, Trip/Fault, and Relay Status.

• Built-in relay output for control or alarm signaling.

• Compact, DIN-rail / panel-mountable design for easy integration into switchboards.

• Factory-calibrated for accuracy and long-term stability.

• Wide operating voltage: 415 V AC ± 10%, 3-phase, 50 Hz.

• Rugged design suitable for continuous industrial operation.

Applications:

• Protection of motors, pumps, compressors, and fans in three-phase networks.

• Industrial control panels, MCCs, and distribution systems.

• HVAC, refrigeration, and water-treatment systems.

• Any application requiring continuous monitoring of phase and voltage quality.
