ASCO Power Manager - Series 7000 Soft Load

Advanced Power Control and Monitoring
5200 Power Manager XP

Two Power Managers, one each dedicated to utility and onsite power sources, provide protective relay functions for reliable parallel operation of the sources in the 7000 Series Soft Load Power Transfer Switch. The power managers include digital inputs and outputs (Device 85).

In addition to directional power, a directional over-current device provides the most reliable protection against undesirable back-feeding of onsite power to the utility grid.
