Description
DIN rail mounting protection relays for use in single and three phase systems. Available in 55mm x 112mm or 100 x 112mm DIN rail cases
Selection Guide
| M200-TVU | DC volts under trip |
| M200-TVO | DC volts over trip |
| M200-TVC | DC 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
