The style and pinout of the DC Connectors on the HPW are the same as the Crest
The better (and cheaper) solution for an external supply is to use the supply designed for the HPW, the model XPS- SW3. This external supply uses the same basic PSU assembly from the HPW, fitted in a 2U chassis. The

This is a standard, 15 amp IEC power inlet connector. A mating cord set is normally supplied with the Console to match local power requirements. Any worldwide AC mains voltage is acceptable, from 100 volts to 240 volts, 50 or 60 Hz. Maximum input power is 200 watts.

ground link
When using an external supply, the Console’s internal supply is plugged into an AC outlet AND the console is con- nected (via the DC cable) to an external supply which has its own AC plug and outlet.These two, different AC outlets may be at different ground potentials. Depending on various (sometimes unknown) conditions, a

Normally, the supplied metal link ties the two
NOTE: Removing this link DOES NOT lift the chassis of the external supply from the AC safety ground, the chassis of the power supply enclosure is ALWAYS attached to the 3rd wire ground of the AC inlet connector. That connection is there for safety reasons- it shunts (to the AC ground plug) any dangerous internal faults that may contact the chassis metalwork. AT NO TIME SHOULD THIS 3rd WIRE GROUND BE DEFEATED (by cutting off the AC plug ground pin or by improperly using a
