Maxchek 400 Maximum Demand Controller
"Maxchek 400 is a smart maximum demand controller withstandard size 96x96 mm specifically designed for industries tokeep a check on their maximum demand. It gives an alarm whendemand approaches a preset value and also switches off nonessentialloads in a pre-programmed logical sequence. Thispredictive maximum demand controller (MDC) allows stage wiseload restoration to maximize the use of a sanctioned load.Maxchek 400 is most suitable for the demand control ofindustrial consumers, HT consumers and commercialestablishments. It also supports ethernet module forcommunication."
