ATE-DMG
VOLTAGE/CURRENT STABILIZED
POWER SUPPLY
I — INTRODUCTION
1.1. SCOPE OF MANUAL.
This Quick Start Guide
covers simple installation and local operation of the Kepco
ATE-DMG Series of 1000W voltage and current stabilized
d-c power supplies. Full specifications, features and
instructions are found in the associated Operator Manual
that can be downloaded free from the Kepco web site at:
www.kepcopower.com/support/opmanls.htm#ate-dmg
1.2. DESCRIPTION.
The Kepco ATE-DMG with pro-
grammable overvoltage protector is a precision stabilized
power supply which can deliver either stabilized output volt-
age or current. The prevailing operating mode is indicated
by LED mode indicators on the front panel. Operating mode
crossover is automatic and may be monitored remotely by
commands provided via the GPIB port. A digital front panel
display shows the output voltage and output current. This
power supply has a linear and fully dissipative NPN pass
transistor section driven by high-gain, integrated circuit
amplifiers. The output of the power supply is fully program-
mable via either the GPIB port or the front panel keypad or
from an external analog reference when enabled from the
front panel menu. Terminals are also provided for remote
error sensing, as well as for the connection of the output
capacitor directly at the load.
The ATE-DMG power supply features user-selectable
“slow” or “fast” operating modes. Slow mode operation is
recommended for applications demanding a constant volt-
age source. Fast mode operation is best if the output volt-
age must change rapidly, either in response to an external
programming signal or, if the ATE-DMG is used as a cur-
rent stabilizer.
The ATE-DMG power supply is delivered for “slow mode”
operation. Refer to Operator Manual (see PAR. 1.1) for
converting the ATE-DMG power supply to “fast mode” oper-
ation.
A continuously adjustable overvoltage protection circuit is a
built-in feature. The trigger point of the overvoltage protec-
tor may be set (or checked) under actual operating condi-
tions by the front panel accessible setup controls.
Units are shipped for 115V a-c operation (105V to 125V
a-c), 47 to 63Hz. For operation at 104V a-c, 208V a-c or
230V a-c refer to the full Operator Manual (see PAR 1.1).
1.3. EQUIPMENT SUPPLIED.
• 115V a-c Line Cord terminated with NEMA 5-20P
plug.
1.4. ACCESSORIES (NOT SUPPLIED)
IEEE 488 Cables to connect ATE-DMG power supply to
GPIB bus (1, 2 or 4 meters long) are available. See Opera-
tor Manual for complete list of accessories.
II — SAFETY.
Exercise care in making all connections to and from the
ATE-DMG terminals. There are no operator serviceable
parts inside the case
WARNINGS
1. Remove a-c power from the ATE-DMG before making
any connections.
2. Wires and/or cables, connected from the ATE-DMG ter-
minals to external components or programming devices
must be properly insulated and securely terminated on
both sides to make accidental touch impossible.
3. The ATE-DMG chassis and cover must be safety-
grounded to a reliable a-c source ground. A safety-
ground may be established by using the power cord
supplied with a grounded a-c power outlet or, if the latter
is not available, by means of a separate wire, from the
provided GROUND terminal (at the rear barrier strip) to
a reliable a-c source ground point.
