M200-TVUDC volts under trip
M200-TVODC volts over trip
M200-TVCDC volts combined under and over trip

Typical Applications

The M200 DC voltage trip are commonly used for monitoring battery voltage conditions, but can be used in any application where dc voltage level is critical. The user is provided with an adjustable set point of 0-80% on under units and 40 to 120% on over units.

The differential is internally set at 5%, no time delay is provided. As is common with all M200 relays, on over units the relay de-energises when the input signal goes below the trip point. A red LED indicates the state of the relay whilst a green LED indicates the state of the power supply
