(2 Quad and 4 Quad)
Power supplies for the controller are generated from the
single phase auxiliary supply via a Switched Mode Power
Supply. The incoming supply is directly rectified to provide
a high voltage dc power rail. A high voltage transistor
switches this rail on to the primary of a high frequency
transformer, the output of which is rectified and smoothed to
provide the dc power supply rails. The +15V dc rail is
monitored via a reference element and a control signal
returned via an opto-isolator to the control element of the
high voltage switching transistor. The other dc rails (-15V &
+24V dc) are generated via separate secondary windings
which are rectified and smoothed, with a separate SMPS
element providing a regulated +5V dc rail. The SMPS
operates over a0n input voltage range of 110V to 240V ac
±10%, 50/60Hz.
