Maximum Demand Control

Maximum Demand and Peak Load Control

Our Maximum Demand controller has built-in Peak load facility which is useful in countries like India where load has to be under defined limit or restriction imposed by the electricity board for specific time period every day.
The purpose of Maximum demand (MD) is, not to exceed the contracted maximum demand limit. MD predicts the demand and automatically shed / restore loads based on load priorities. MD utilizes the load optimally, always ensuring that it does not cross the sanctioned demand and thus saves from heavy penalties imposed by electricity boards.
