3.4 Power Supply

The following diagram illustrates wiring between the PS-33 power supply
and the AC-225. It is recommended to add a 12VDC lead acid backup
battery if the main power supply fails. If the main output is 12VDC, wire it
to the PS-33, whose load ratings are 1.5A / 0.9A / 0.3A. Otherwise support
your power supply according to the output requirements. For further
information refer to the Outputs section on page 24.
A 12V 7AH battery will provide 3 hours of backup operation.
