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 an input voltage range of 110V to
240V ac ±10%, 50/60Hz.
