Power supply -- American Reliance Inc. SPS Series

Manufacturer:
American Reliance Inc.
Model: SPS Series
Date: 2005
Category: Measurement instruments
Group: Power supply
Description: Programmable DC Power Supply
Information:
American Reliance’ SPS Series 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.
SPS Series power supplies are current
fed and are more tolerant to abusive loads than conventional
switching power supplies.
SPS Series power supplies offer an unusual blend of both
analog and digital control. Two front
panel potentiometers are available to set voltage and
current for stepless analog control.
Alternatively, voltage, current, over voltage trip, and over
current trip may be programmed through
a rear connector via resistance, voltage, or current. With
simple configuration changes, the SPS
Series power supplies will accept keypad entries and up/down
key presses for programming voltage,
current, over voltage trip, and over current trip. Key
strokes are kept to a minimum by a repeat last
command feature. RS232 communications is embedded in the
control circuitry allowing full
computer control with SCPI commands. An optional IEEE-488 to
RS232 converter, Ethernet to
RS232 converter, and other communications converters are
available to echo commands over the
communications bus.
SPS Series 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 communications. Sensing can be
established at the output terminal
of the power supply or through a rear terminal block for
sensing at the load. 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.
SPS Series power supplies incorporate an optically isolated
feedback system. The result is that all
user interface circuitry is reference 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.
SPS Series 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.
SPS Series 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.
One-hundred memory states are available to program voltage,
current, over voltage trip, over current
trip, and time period. Set points can be auto sequenced with
time or external triggering. Special
programming codes allow repeating to create a power function
generator. The first 10 memory
states are displayed on the front panel to simplify
programming tasks.
SPS Series power supplies offer an analog input to modulate
the voltage or current setting. This
feature enables the voltage or current setting to be
adjusted by a sensor input, such as a thermistor,
or by monitoring its own voltage or current. Modulation
allows the output to be tailored for
advanced process control applications, battery charging, and
source emulation.
Remote Interface Software is included to provide
sophisticated computer control. This software
provides a virtual control panel to emulate the power
supply’s front panel, a command panel to send
and monitor SCPI commands, a register panel to monitor
registers, and a calibration panel to provide
easy access to calibrate digital potentiometers.
SPS Series 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
clearing, 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 SPS
Series units.
SPS Series 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.
SPS Series 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
American Reliance.
