Product description

The measuring relay RL 9854 of the VARIMETER series monitors overvoltage, undervoltage and voltage range in DC voltage systems. The measurement is very simple and without extensive wiring as there is no auxiliary power supply necessary. The monitoring functions are easily selectable using a single turn switch without complex menu structure. The early detection of up-coming break downs and preventive maintenance avoid expensive damages. As user you profit from the reliability and availability of your plant.
