The PX3TS has two inlets: INLET 1 and INLET 2. These inlets are to connect to
diverse power sources. One inlet is configured as the primary (preferred), and
the other is configured as the standby (alternate). The factory default preferred
power source is Inlet 1, and the default alternate source is Inlet 2.
When power is available from both sources and power quality is identical, the
PX3TS selects the preferred inlet to power the load. If a power failure occurs on
the preferred source or its power quality deteriorates below an acceptable
level, the power can be transferred from one inlet to the other automatically or
manually on the PX3TS. Power transfer does not interrupt the operation of the
connected equipment. The transfer time takes only 4-8 milliseconds (1/4 AC
cycle). See the diagram below.
