Typical Applications
The M200 AC voltage relay provides voltage monitoring and protection in both single and three phase systems.
They are used in applications such as mains failure, regulation of power supplies and to protect voltage sensitive equipment.
Under, over and combined under/over units are available.
The relay operates when the externally adjustable trip point is reached. An external differential control is provided with adjustment 1-15%. The differential ensures that the parameter being measured returns to % set above or below (depending on whether it is under or over unit) the trip point before the relay returns to its original state.
As is common with al/the M200 relays; on over units the relay energizes when the input signal exceeds the trip point.
On under units the relay de-energizes when the input signal goes below the trip point.
A red LED indicates the state of the relay, whilst a green LED indicates the condition of the power supply.
