Altech Monitors & Monitoring Relays
Altech Monitors and Monitoring Relays are available in various configurations, including energy monitors, current monitor relays, and voltage monitoring relays. The energy monitors offer a range of functions, including line-to-neutral voltage measurement, current measurement, reactive energy measurement, active energy measurement, and power factor measurement. These energy monitors feature a one- and three-phase universal energy meter, a voltage rating of up to 277VAC, one digital input, and two digital outputs. Current monitor relays detect current anomalies on the line side, and the overcurrent relay trips when a current rise is detected above a particular set point. The voltage monitoring relays are connected to the line side of equipment and are sensitive to abnormal conditions that may occur in various ways. These voltage relays from Altech trip when sensing both undervoltage and overvoltage conditions, helping prevent equipment failure.
