internal supply
The HPW is equipped with an internal power supply, based on a universal input, switch-mode design. As such, you can power the HPW from any worldwide AC mains voltage from 100 to 240 volts, 50 or 60Hz. Input power is approx 200 watts maximum (56-chan console), so power requirements are minimal. A standard IEC power-inlet socket is used, along with a country-specific line cord, to bring AC power into the Console.The power supply, along with the entire console, is UL/CUL and CE rated for safety and emissions. There is an internal fuse for safety reasons, but no external fuse is provided.There are no user serviceable parts inside. The entire PSU assembly would be replaced in case of failure.
The power supply is always located under the first input module to the left of the Master module (viewed from the front of the console).The rear-panel of that Input module has the normal compliment of input connectors, plus the additional, power- supply related controls.
119AC input
A standard 15 amp, IEC power-inlet socket is used to bring AC power into the Console. Use the appropriate line cord for the country of operation. Any worldwide voltage is acceptable, from 100 to 240 volts, 50 or 60Hz. Input power is 200 watts max.
120on-off switch
This switch turns the internal supply on or off. It has no direct effect on the External DC connector.
121Ext DC Connector
line cord is sup-
plied with the HPW to match the country of des- tination. If lost or missing, a standard, approved IEC cord-set can be used.
This 7-pin connector is used to bring DC voltages into the console from a back- up, or stand-by (redundant) supply. These externally-sourced voltages are “diode- steered,” along with the voltages from the internal supply, to provide power for the console. Although this connector is protected against incorrect hookup (reverse or over-voltage), ONLY Crest-approved power supplies should be used.
