MULTIPROCESSOR EMBEDDED CONTROL
ENHANCED CONTROLS AND DIAGNOSTICS
PQ SERIES III power supplies have extensive diagnostic functions -- all of which, when activated, take command to shut down
the system. Diagnostic functions include phase loss, excessive thermal conditions, over voltage trip, over current trip, fuse clear-
ing, and program line. Program line monitors externally applied analog set point signals to insure they are within the specified
range. Upon a diagnostic fault condition, main power is disconnected and the diagnostic condition is latched into memory.
Pressing the clear key clears the memory. All diagnostic functions can be monitored through a rear connector. Furthermore,
control functions can also be set through the rear connector to allow simultaneous control of one or more PQ SERIES III units.
PQ SERIES III supplies have three levels of over voltage/current protection: shutdown of controlling insulated gate bipolar
transistors (IGBT’s), disconnect of main power, and input fuses. After an over voltage/current trip condition, the supply must be
reset.
PQ SERIES III power supplies have push button start/stop controls. These controls are tied to a mechanical contactor which
operates with the electronic switches to break the ac mains when stop is commanded. Unlike competing products, an off means
both an electrical and mechanical break in the power circuit — not a break in an electronic switch. Safety comes first at Magna-
Power Electronics.
DESIGNED FOR SAFETY
REMOTE INTERFACE SOFTWARE
INCLUDED WITH ALL MODELS
The Remote Interface Software is shipped with PQ SERIES III
power supplies. The software provides the user with a quick
method to operate a Magna-Power Electronics’ power
supply under computer control. The Remote Interface
Software has six windows: the Virtual Control Panel,
Command Panel, Register Panel, Calibration Panel,
Firmware Panel, and Modulation Panel. The Virtual
Control Panel emulates the front panel of the PQ
SERIES III power supply, the Command
panel programs and reads SCPI
commands with user friendly but-
tons, the Register Panel programs
and reads registers, the Calibra-
tion Panel enables calibration of
the digital potentiometers, the
Firmware Panel enables the pro-
gram stored internal to the power
supply to be upgraded, and the
Modulation Panel eases program-
ming of modulation parameters.

PQ SERIES III power supplies contain circuitry to work harmoniously with other power equipment. Step-start contactors are
used to keep inrush current below full scale operating current. Filter components lower current harmonic content emanating
from the power supply and increase power factor to levels beyond 90%. Every power supply is tested at 90 to 125% nominal line
to insure satisfactory operation even under the worst line voltage conditions
