An MD controller enables the user to program the threshold values of maximum demand and initiate actions i.e. alarm or cut off load when maximum demand / forecast demand / present demand crosses the threshold values. This helps the user to ensure that demand does not exceed the sanctioned limit and avoid paying huge penalties.

Parameters: V, A, F, kW, KVA, kVAr, kWh, kVAh, kVArh, PF, Runhr, Onhr, Intr, Phase angle, THD, Events, Neutral current, Max Demand (with RTC) with 4 relay outputs.
