The NPS-I & NPS-II switches allows instantaneous transfer of load
between two power sources. It can be used to ensure complete
redundancy of power supply upto the last piece of wire. It is useful in
many applications, where redundant power supply is available,
either from two UPS systems or one UPS and bypass source.
These switches are comprising of semiconductor switches, they
ensure continuity of powertothe load in the eventoffailure of one of
the power sources. They have different user selectable parameters
and in-built microprocessor.
