Liebert Network Power Switch I and II

The NPS-I and NPS-II switches allow instantaneous transfer of load between two power sources. It can be used to ensure complete redundancy of power supply up to the last piece of wire. It useful in many applications where redundant power supply is available, either from two UPS systems or one UPS and bypass source.
