Power Supply (8821)
The Power Supply, Model 8821, provides variable single-phase AC, variable three-phase AC, and variable DC at power levels needed to operate the 0.2 kW EMS equipment modules.
A five-wire flexible power cord, terminated with a five-prong twist-lock plug and line cap, feed the power supply. For safety, a mechanical interlock on the line cap prevents the removal of an energized power supply from its locked position in the EMS Workstation (Model 8110, 8131, 8133, or 8134).
