Under + Over Voltage Relay

Description

Under + Over Voltage Relay – Flogan Complete Voltage Protection Device

The Flogan Under + Over Voltage Relay is a comprehensive protection solution designed to safeguard electrical equipment such as generators, motors, pumps, and transformers from both low voltage and high voltage conditions.

It continuously monitors input voltage and compares it with preset thresholds. If voltage falls below or rises above the defined limits, the relay activates and triggers protection mechanisms.

The relay is equipped with two sets of potential-free changeover contacts for effective breaker tripping and control operations.

It features externally adjustable potentiometers for both under and over voltage settings, along with hysteresis control (5–15V) to avoid false tripping during transient conditions.

A fixed time delay of 2–4 seconds ensures stable operation, while the relay automatically resets once voltage returns to normal range. LED indicators provide clear status visibility.

Ideal for AMF panels, industrial power systems, and automation applications, this relay ensures complete voltage protection.
