3.4 Power Supply
Figure 6 illustrates wiring between the PS-33 power supply and the AC-425. It
is recommended to add a 12
VDC lead acid backup battery if the main power
supply fails. If the main output is 12 VDC, wire it to the PS-33, whose load
ratings are 1.5 A/0.9 A/0.3 A; otherwise, you should support your power
supply according to the output requirements. For more information, refer to
Section
4.3. A 12-V 7 AH battery provides 3 hours of backup operation.
