5.5 POWER SUPPLY
The power supply provides to the monitoring,
for the products. power is provided in the form of
loosely outputs of and -15
Tbis power supply is to
derive power from the AC inputs and provide outputs referenced to the output
neutral.
The boot strap/start-up circuit provides the necessary to start the supply
from the input source. provide3 the closed loop and drive for
the DC to AC
frequency. Voltage
control provides the output voltage
feedback for IC power.
The passes energy from the. input circuit common source to the
output circuit common load. Output of the isolation
is
to provide outputs of -15 VDC.
An input voltage monitor continuously and compares the input voltage and
shut the power supply off during undervoltage conditions. Air
sensing provides voltage
the sir tempera&e on the Power Supply
board.
