The 750-W and 265-W AC power supply modules are autoranging units that support input voltages between 100 and 240 VAC. The 1150-W power supply module is an autoranging unit that supports input voltages between 115 and 240 VAC. The DC power supply module has dual input feeds (A and B) and supports input voltages between 36 and 72 VDC. The AC power supply modules include a power cord for connection to an AC power outlet. The 1150-W and 750-W modules use a 16-AWG cord (only North America). All other modules use an 18-AWG cord. The DC power supply module requires wiring to a DC-power source.
