Maximum Demand Controller

Maximum Demand Controller

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.
