Overview

Controls AC and DC voltages, with and without memory. When the voltage reaches the threshold set point the output changes state at the end of the selected time delay. Once the voltage drops below the hysteresis (% of the threshold) the output changes instantly. In memory mode the relay remains in the faulted condition until the unit is reset manually. Approvals: UL and cUL Listed and CSA Certified. MUS Series: Underfoot and Overvoltage — Monitors supply voltage. MUSF Series: Undervoltage/ Overvoltage Window — Monitors supply voltage. HU Series: Undervoltage and Overvoltage — Monitors separate voltage from unit supply voltage. All models have 5 amp output relay. Protect expensive equipment from over and under voltage problems.
