Conditions of Conformance

When this product is used in applications governed by the requirements of the EEC, the following restric­tions and conditions apply:

1. For European applications, requiring com plian c e to the Low Voltage Directive, 73/23/EEC, this power
supply is considered a component product, designed for “built in“ applications. Because it is incom­plete in construction, the end product enclosure must provide for compliance to any remaining electri­cal safety requirements and act as a fire enclosure. (EN61010-1:2001, Cl. 6, Cl. 7, Cl.8, and Cl. 9)

2. This power supply is designed for stationary installation, with mains power applied via a detachable
power supply cord or via direct wiring to the source power terminal block.

3. This power supply is considered a Class 1 (earthed) product. It is intended for use as part of equip­ment meant for test, measurement and laboratory use, and is designed to operate from single phase,
three wire power systems. This equipment must be installed within a suitably wired equipment rack,
utilizing a three wire (grounded) mains connection. See wiring section of this manual for complete
electrical wiring instructions. (EN61010-1:2001, Cl.6.10.1)

4. This power supply has secondary output circuits that are considered hazardous, and which exceed
240 VA at a potential of 2V or more.

5. The output wiring terminals of this power supply has not been evaluated for field wiring a nd, th erefore ,
must be properly configured by the end product manufacturer prior to use.

6. This power supply employs a supplementary circuit protector in the form of a circuit breaker mounted
on the front panel. This circuit breaker protects the power supply itself from damage in the event of a
fault condition. For complete circuit protection of the end product, as well as the building wiring, it is
required that a primary circuit protection device be fitted to the branch circuit wiring. (EN61010-1:2001,
Cl. 9.5)

7. Hazardous voltages are present within this power supply during normal operation. All operator adjust­ments to the product are made via externally accessible switches, controls and signal lines as speci­fied within the product operating instructions. There are no user or operator serviceable parts within
the product enclosure. Refer all servicing to qualified and trained Kepco service technicians.

accidental contact with hazardous internal voltages is provided:

There are no operator serviceable part s or adjustment s within the product enclosure.
Refer all servicing to trained service technician.

Source power must be removed from the product prior to performing any servicing.

This product is factory-wired for the nominal a-c mains voltage indicated on the rat­ing nameplate located adjacent to the source power connection on the product's rear
panel. To reconfigure the product input for other nominal mains voltages as listed
herein, the product must be modified by a trained service technician.

2. Grounding

This product is a Class 1 device which utilizes protective earthing to ensure operator safety.

The PROTECTIVE EARTHING CONDUCTOR TERMINAL must be properly con­nected prior to application of source power to the product (see instructions on instal­lation herein) in order to ensure safety from electric shock.

PROTECTIVE EARTHING CONDUCTOR TERMINAL - This symbol indicates the
point on the product to which the protective earthing conductor must be attached.

EARTH (GROUND) TERMINAL - This symbol is used to indicate a point which is
connected to the PROTECTIVE EARTHING TERMINAL. The component installer/
assembler must ensure that this point is connected to the PROTECTIVE EARTH­ING TERMINAL.

CHASSIS TERMINAL -This symbol indicates frame (chassis) connection, which is
supplied as a point of convenience for performance purposes (see instructions on
grounding herein). This is not to be confused with the protective earthing point, an d
may not be used in place of it.

3. Electric Shock Hazards

This product outputs hazardous voltage and energy levels as a function of normal operation. Operators
must be trained in its use and exercise ca ution as well a s common sense during use to prevent a ccidental
shock.

This symbol appears adjacent to any external te rminals at wh ich haza rdous volt age
levels as high as 500V d-c may exist in the course of normal or single fault condi­tions.

This symbol appears adjacent to any external te rminals at wh ich haza rdous volt age
levels in excess of 500V d-c may exist in the course of normal or single fault condi­tions.

1.1 SCOPE OF MANUAL

This manual contains instructions for the installation, operation and maintenance of the ATE­DMG series of voltage and current stabilized d-c power supplies, manufactured by Kepco, Inc.,
Flushing, New York, U.S.A.

1.2 GENERAL DESCRIPTION

The Kepco ATE-DMG with programmable overvoltage protector is a precision stabilized power
supply which can deliver either stabilized output voltage 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 vo ltage and ou tput cu rrent. T his powe r supp ly has a line ar
and fully dissipative NPN pass transistor section driven by high-gain, integrated circuit amplifi­ers. The output of the power supply is fully programmable via either the GPIB port or the front
panel keypad. Terminals are also provided for remote e rror 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 voltage source. Fast
mode operation is best if the output voltage must change rapidly, either in response to an exter­nal programming signal or, if the ATE-DMG is used as a current stabilizer.

SECTION 1- INTRODUCTION

The ATE-DMG power supply is delivered for “slow mode” operation. See Section 2, par.

2.7 for converting the ATE-DMG power supply to “fast mode” operation.

A continuously adjustable overvoltage protection circuit is a built-in feature. The trigger point of
the overvoltage protector may be set (or checked) unde r actual op erating co nditions by th e front
panel accessible setup controls (refer to Section 2 of this manual).

Power transistors and drivers on all ATE-DMG designs are mounted onto highly efficient, pat­ented heat sink assemblies which are cooled by low-noise fans. The ATE-DMG main chassis
assemblies, as well as the wraparound covers, are constructed from cold-rolled steel The front
panels are made from aluminum (refer to the “Mechanical Outline Drawing,” Figure 1-2).

1.3 SPECIFICATIONS

Table 1-1 lists the output parameters applicable to individual models. Table 1-2 lists general
specifications applicable to all full-rack models except where otherwise noted. Table 1-3 lists
dynamic specifications and Table 1-5 lists static specifications. Mechanical specifications are
presented in the mechanical outline drawing, Figure 1-2.

1.4 LOCAL CONTROL

Front panel keypad entries are utilized for setting and adjusting output voltage and current
under local control. The keypad's keys are organized to either directly execute commands, or to
introduce a program that can either be run once or cycled. Calibration of the unit is facilitated by
a password -protected, menu-driven procedure from the front panel.

1.5 REMOTE CONTROL

The ATE-DMG Power Supply can be remotely controlled directly via the IEEE 488.2 (GPIB) bus
using SCPI commands. All features available in local mode can also be accessed remotely. In

ATE-DMG OPER 042314 1-1

addition, output voltage and current can also be controlled by external analog reference volt­ages (see PAR. 3.5).

1.6 FEATURES

1.6.1 OVERVOLTAGE/OVERCURRENT PROTECTION

Overvoltages and Overcurrent protection values can be individually programmed via the front
panel keypad or remotely via the IEEE 488.2 (GPIB) using SCPI commands (refer to PARs.

3.4.9 and 3.7). When overv oltage or overcurrent is detect ed, the power supply is programmed
to 0 volts with a small current and the power supply responds as if an *RST command was
received over the GPIB bus. See Table 1-4 for maximum programmable settings.

1.6.1.1 PROGRAMMABLE OVERVOLTAGE/OVERCURRENT DELAY

Changing the output settings may cause large output transients (common with reactive loads)
that can trip the overvoltage/overcurrent protection. The ATE-DMG can be programmed to delay
sensing of overvoltage/overcurrent protection when output settings are changed to avoid inad­vertent tripping. After the delay, the programmed overcurrent/overvoltage setting is effective.
Protection can be delayed up to approximately 8 seconds after the ou tput setting s are cha nge d.
Refer to PAR. 3.4.10.

ATE-DMG OPER 042314 1-5

1.6.1.2 CROWBAR CIRCUIT

An overvoltage crowbar circuit protects the load from momentary or long term overvoltages. The
crowbar conducts across the power supply output and the AC POWER SWITCH/CIRCUIT
BREAKER is tripped if such overvoltage occurs. The setting of the front panel LEVEL control
determines the threshold between the operating voltage of the power supply and the level at
which the crowbar circuit will be activated. The crowbar level is set from the front panel (refer to
PAR. 3.3). This feature is used as a hardware backup protection in case of overvoltage.

1.6.2 NON-VOLATILE STORAGE OF PROGRA MMED SEQUENCE S OR ACTIVE SETTINGS

The ATE-DMG Power Supply contains 40 memory locations that can be used either to prepro­gram a sequence of output values or to store the active settings. For programming sequences
each memory location accommodates six parameters: output voltage, output current, Overvolt­age, Overcurrent, Time (how long the parameters are in effect) and the next address in the
sequence. Values are stored in the non-volatile memory, and are retained when the unit is
turned off. Refer to PAR. 3.4.12.

The same 40 memory locations are also available to save the active programmed settings
(V SET, I SET, OV SET and OC SET). The saved setting can be recalled by specifying the
memory location.

1.6.3 USER-DEFINED VOLTAGE/CURRENT LIMITS

The ATE-DMG output can be programmed not to exceed user-defined values. For example, the
ATE 25-40DMG, which has a maximum capacity of 25V, 40A, can be limited to 5.5V, 20A for
working with circuitry that might be damaged by higher le vels. Once the limits are set, the power
supply becomes, in effect a 5.5V, 20A supply and values exceeding the limit values will not be
accepted. Refer to PAR. 3.4.11.

1.7 EQUIPMENT SUPPLIED

The unit is shipped with a standard Power Cord, 115 VAC (USA, standard configuration plug).

2.3 SOURCE POWER REQUIREMENTS

This power supply is normally configured for operation on a single phase, nom inal 115V a-c line.
For conversion to other a-c source volt ages, refe r to Figure 2-4. Select your nominal source vo lt­age and change the links on the barrier strip of T201 according to the table pr ovided in Figure 2-

4. The circuit breaker (CB101) remains equally effective at all input voltages.
