Kepco's 1000 watt instrument-grade
digital power supplies, series ATE-DMG,
are linear low-noise power supplies
designed to respond very quickly and
precisely to voltage and current setting
instructions delivered interactively by
the GPIB (IEEE 488.2) or from a front
panel keypad. When programmed from
the bus, the ATE-DMG power supplies
respond to the SCPI (Standard Commands
for Programmable Instruments) common
language for instruments
used in an automatic
test system.
ATE-DMG digital power supplies are locally controlled exclusively
through a 24-key panel keypad. This offers full control over the
voltage and current settings, as well as overvoltage, overcurrent and
a time setting. The keypad allows the user to store as many as 40
combinations of these parameters and to loop back onto itself to
produce repetitive programs. The setting values as well as the actual
output delivered to the load are displayed in the two-line, 16 character
back-lit LCD.
Remote control is via the built-in IEEE-488.2 interface that offers
full talk-listen functionality on the bus. The settings and the actual
voltage-current values are read back on the bus upon command. The
output can be modulated by analog signals in the same fashion as
Kepco's non-digital ATE-series power supplies. The ATE-DMG
retains the ATE-series' signature high-speed control mode which
enables rapid output programming and fast voltage recovery to load
changes in current-control mode.
ATE-DMG are CE marked per the
Low Voltage Directive (LVD), EN61010-1.

FEATURES
• Linear control for low noise: 100 microvolts typical in voltage mode; and high
precision: 0.0005% source effect {regulation}
in voltage mode.
• Voltage and current control with equivalent
performance. A high speed mode allows
fast-recovery current-controlled stabilization
into a varying load.
• Overvoltage and overcurrent settings
individually programmed by the front
panel keypad or remotely by the bus with
a programmable delay to allow for reactiveload transients.
• A manually set overvoltage crowbar
monitors the output to protect sensitive
loads. This setting is done only from the
front panel and cannot be modified by the
keypad or GPIB.

The dynamic characteristics are tabulated in the Dynamic
Specifications Table. Analog control of voltage and current is via a pair
of remote signals (0-10V for voltage, 0-1V for current). Two uncommitted
op-amps are provided internally to allow available control signals
to be scaled and, if necessary, inverted to suit the circumstances.

• Non-volatile storage of programmed
sequences or active settings. The ATE-DMG
contains 40 memory locations that store
voltage, current, overvoltage, overcurrent,
time (how long the parameters are in effect)
and the next address in the sequence.

• Local control: Front panel keypad entries are
used for setting and adjusting the output. The
keypad can be used to execute commands
directly or to introduce a program to be run
later or cycled. Calibration of the ATE-DMG
is done from the keypad using a passwordprotected, menu-driven procedure.
