13.3.5. POWER SUPPLY/CIRCUIT BREAKER
The analyzer operates on 100 VAC, 115 VAC or 230 VAC power at either 50 Hz or
60Hz. Individual instruments are set up at the factory to accept any combination of
these five attributes. Power enters the analyzer through a standard IEC 320 power
receptacle located on the rear panel of the instrument. From there it is routed through
the ON/OFF Switch located in the lower right corner of the Front Panel.
AC Line power is stepped down and converted to DC power by two DC Power Supplies.
One supplies +12 VDC, for various valves and valve options, while a second supply
provides +5 VDC and 15 VDC for logic and analog circuitry as well as the power
supplies for the Photometer and IZS UV Lamps.
All AC and DC Voltages are distributed via the relay PCA.
