A DC power distribution system can be configured to utilize a variable number of AC power distribution units. Installation of a converter unit in place of a PDU and resetting of associated switches permits inexpensive and rapid reconfiguration of the system without interrupting power supply to current receiving units. Techniques such as mechanical keying and sense switches minimize the possibility of human error in the reconfiguring operation.
