Description

LINETRAXX® VMD258 is a voltage relay system that can monitor three-phase AC systems and detect undervoltage and overvoltage. As a neutral conductor connection is not needed, it works well for 3AC systems. The relay system takes its voltage from the system it monitors. With the help of a double isolation system, it is possible to isolate the supply of the electronics, the relays and the connection meant for the external energy storage device. The relay system has special transformers that can attenuate interferences. It is also easy to adjust the response values for undervoltage and overvoltage. The system is so efficient that it replaces SUR35x series.
