PL1100 Power Supply
General Description
The PL1100 is a linear power supply with a rated output of 1120W (80V/14A) for use with
ViX and XL series drives. The supply requires a suitably rated transformer supplying 50V
AC RMS for the HV and 20V AC RMS for the +24V DC. The use of the PL1100 offers the
following benefits:
• Provides 80V HV and +24V DC output
• Single or three phase operation
• Built-in power dump switch
• Integral fusing
Figure 3-4 shows the PL1100 output wiring for two ViX drives. This illustrates how to route
the main HV supply separately to each drive. The lower current requirements of the +24V
logic/brake supply can allow the wiring to be linked between drives.
For full installation instructions see the PL1100 Power Supply leaflet 1600.323.XX.
In Figure 3-4 the drives are wired individually to the PL1100, alternative daisy chain wiring
can be used.
