DC Volt Trip

Posted

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

Application

For over protection, under protection and combined under & over protection available in AC current AC voltage & frequency versions. Millivolt trip, DC voltage trip, Reverse Power, Phase sequence & Phase balance relays also available in our extensive range of protection relays..

Selection Guide

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