The 1100-W power supply module is an auto ranging unit that supports input voltages between 115 & 240 VAC. Each AC power supply module has a power cord for connection to an AC power outlet. The 1100-W & 715-W modules use a 16-AWG cord (only North America). All other modules use an 18-AWG cord. The DC power supply module must be wired to a DC power source.
