RUGGED CURRENT FED TECHNOLOGY
HIGH EFFICIENCY OPERATION
INNOVATIVE
Magna-Power Electronics’ PQ SERIES III combines the best of dc power
processing with multiprocessor embedded control. A combination of high and
medium frequency power processing technologies improves response, shrinks
package size, and reduces cost. PQ SERIES III power supplies are current fed and
are more tolerant to abusive loads than conventional switching power supplies.
SCALABLE POWER
PQ SERIES III power supplies offer both master/slave parallel and series
operation. This enables two or more power supplies to be placed in parallel for
increased output current or in series for increased output voltage. With master/
slave operation, power supplies operate at near equal voltage and current.
PQ SERIES III power supplies can operate as a voltage source or current
source depending on the control settings and load conditions. If the power
supply is operating as a voltage source and the load increases to a point beyond
the current command setting, the power supply automatically crosses over to
current mode control and operates as a current source at that setting.
LOAD DEPENDENT AIR OR OPTIONAL WATER COOLING
PQ SERIES III power supplies are designed to operate at rated load 24 hours per day. Standard air cooled units are equipped
with variable speed, load dependent blowers to maintain comfortable margins for removing heat from sensitive power semicon-
ductors. Variable speed operation maximizes fan life and a minimizes external environmental hazards.
Optional water cooled models contain integrated semiconductor chillers and air to water heat exchangers to manage cooling
of heat producing components. This option allows the power supply to be sealed from the environment enabling placement in
harsh environments. These units provide long life in plating facilities, electrodionization treatment plants, shipboard, and other
corrosive environments. Water cooling also permits power supplies to be stacked in high density equipment racks where air cool-
ing is not possible or desireable.
UNPARALELLED CONTROL
PQ SERIES III power supplies can be configured through the front panel for
different applications. The power supply can be programmed to have its control
functions accessible from the front panel, rear connector, or through RS232 com-
munications. Sensing can be established at the output terminal of the power sup-
ply or through a rear terminal block for sensing at the load. A smart remote sense
detector checks whether or not sense leads are present eliminating the potential
of uncontrolled operation. An external interlock can be set to enable operation
only when an external connection is made. Even calibration has been simplified
with front panel access to calibration digital potentiometers.
PQ SERIES III power supplies incorporate an optically isolated feedback system.
The result is that all user interface circuitry is referenced to earth ground -- not
the negative terminal of the power supply. This enables users to connect external
circuitry without concern of ground loops or voltage breakdown.
