Dold BD9080.12/004 3AC750V Tv=Ta=0,1-30s, Phase monitor, sku: 0069431

The Phase monitor BD 9080 of the VARIMETER PRO series monitors over and undervoltage, asymmetry, power failure as well as wrong phase sequence at three-phase networks . The measurement is very simple and can be carried out without much wiring effort, as no separate auxiliary voltage is required. Early detection of impending failtures and preventive maintenance prevent costly damage and as a user you benefit from the operational safety and high availability of your system.
