3. Introduction
3.1. What is ITS for?
ITS stands for Intelligent Transfer Switch. The function of the
ITS is to ensure supply of power to the load from multiple
power sources by switching from one to another when any of
the input sources fails, without interruption. Source
and
can be connected with UPS and source
can be the AC Utility
or Stabilizer or Generator.
3.2. Redundancy
When all the above said three sources are available, during
the operation if UPS-1 fails the output supply of ITS 3000 will
be transferred to UPS-2 automatically without any affect to
the connected load and also UPS-1 can be removed for
repairing without any interruption. If UPS-2 also fails, the
output supply of ITS 3000 will be transferred to AC Utility or
Generator automatically without any affect to the connected
load and UPS-2 can be removed for repairing without any
interruption.
