PCS Load Management

Power Control Systems (PCS) provide for sophisticated management of emergency power systems by managing the connection and disconnection of power sources and equipment loads. This paper focuses on load management controls and features, summarizes their operation, and describes their value. For a basic overview of PCS design and functions, see our prior whitepaper entitled Power Control System Basics.

The most elementary function of a PCS system is to coordinate the connection of power sources and loads to a backup power system following the onset of a power outage. When a utility outage is sensed and/or engine-generators are called to supply building load, a PCS will annunciate the condition as Emergency mode.
