Lovato – PMVF10 – Modular Voltage & Frequency Monitoring Relay, 3U DIN

The Lovato PMVF10 is a modular voltage and frequency monitoring relay, designed to protect single-phase (230 VAC) or three-phase (400 VAC, with or without neutral) systems. It features two SPDT relay outputs and advanced True‑RMS measurement for reliable detection of under/over‑voltage, under/over‑frequency, and ROCOF (Rate of Change of Frequency) faults. Ideal for PV, generator, or grid‑tied power systems requiring robust interface protection.
