1. These power supplies have an extended tab at the connector end that is designed to protect the system and
the power supply from damage if the power supply is installed incorrectly. Otherwise, these power
supplies are functionally compatible with the C3KX-PWR power supplies.

The 350-W and 715-W AC power supply modules are autoranging units that support input voltages
between 100 and 240 VAC. The 1100-W power supply module is an autoranging unit that supports input
voltages between 115 and 240 VAC. The 440-W DC power supply module has dual input feeds (A and
B) and supports input voltages between -36 and -72 VDC. The output voltage range is 51 to 57 V.
Each AC power supply module has a power cord for connection to an AC power outlet. The 1100-W and
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.
Only the DC power module is NEBS-compliant.
