Basler BE3 ac voltage relays provide voltage monitoring and protection in both single and 3 phase systems. This relay can be used in applications such as utility mains failure, regulation of power supplies, and protection of voltage sensitive equipment. Undervoltage, overvoltage and combined under/overvoltage units are available. BE3 ac relays operate when the externally adjustable trip point is reached. An external reset control is provided with adjustment from 1 to 15%. Reset ensures that the parameter being measured returns to percent set above or below the trip point before the relay returns to its original state. On overvoltage units, the relay energizes when the input signal exceeds the trip point. On undervoltage units, the relay de-energizes when the input signal goes below the trip point. A red LED indicates the state of the relay, and a green LED indicates the condition of the power supply.
