Safety
Warnings and cautions are defined and formatted in this manual as shown below.
WARNING
Describes a potential hazard which could result in injury or death, or, a procedure
which, if not performed correctly, could result in injury or death.
CAUTION
Describes a procedure which, if not performed correctly, could result in damage
to data, equipment, or systems.
WARNING—High Energy and High Voltage
Exercise caution when using and calibrating a power supply. High energy levels
can be stored at the output voltage terminals on a power supply in normal
operation. In addition, potentially lethal voltages exist in the power circuit and on
the output and sense connectors of a power supply with a rated output greater
than 40 V. Filter capacitors store potentially dangerous energy for some time after
power is removed.
CAUTION
Operate the power supply in an environment free of flammable gases or fumes. To
ensure that the power supply’s safety features are not compromised, use the
power supply as specified in this manual and do not substitute parts or make any
unauthorized modifications. Contact the service technician for service and repair
help. Repairs must be made by experienced service technicians only.
CAUTION
For Use as a Battery Charger
When you are using any of these power supplies for battery charging applications,
it is essential to provide an appropriately sized fuse or circuit breaker in series
between the power supply output and the battery.
Installation of a protector (fuse or DC circuit breaker) rated for about 115% of the
maximum current rating of the power supply and designed specifically to interrupt
the DC voltage of the battery, will provide adequate reverse polarity current
protection. Where several power supplies are in parallel, it is best to fuse each one,
rather than one large fuse for all.

Description
The 1000 watt DC output power supplies provide low noise, precisely regulated,
variable DC output. Typically they are used for bench and automated test equipment
(ATE) applications. Each unit includes over voltage protection and thermal
shutdown as standard features. Universal AC input allows you to use line voltages
globally without resetting switches or adding options. Built-in power factor
correction gives you full output power from low current/low voltage outlets, reduces
power line interference, and allows you to meet international regulations.
You can select from several remote control choices for either analog or digital
control. For analog control, choose from standard analog control or optional
4-channel isolated programming. Digital control options include RS-232 control or
GPIB programming. You can use the power supply on your benchtop or rack
mounted; each supply occupies less than 3-1/2 in. (2 U) of vertical space. Whether
you are powering batteries, development circuits, and magnet coils or running ATE
systems, the power supply provides the precision and power that you need.
Features and Options
• Models available with voltage ranges from 0-7.5 Vdc to 0-600 Vdc; current
ranges from 0-1.7 A to 0-130 A.

Making J2 Connections
CAUTION
To maintain the isolation of the power supply output and prevent ground loops,
use an isolated (ungrounded) programming source when operating the power
supply via remote analog control at the J2 connector.
CAUTION
Do not attempt to bias the Program/monitor signal return (J2-6) relative to the
power supply output return, as they are connected internally. Use the Isolated
Programming (ISOL) option for control from programming sources at potentials
differing from the supply output return.
Wire Clamp
Connector Screw
Make connections to the J2 connector using its screw-type wire clamps. Before
making any connections, turn the power supply OFF and wait until the front panel
displays have gone out. You can unplug the connector from the back of the unit in
order to make it easier to install the required wiring.

Wiring
WARNING
There is a potential shock hazard at the output and J2 terminals when using a
power supply with a rated output greater than 40 V. Use load wiring with a
minimum insulation rating equivalent to the maximum output voltage of the
power supply. For example, select TEW-105, 105 °C, 600 V wiring for use with a
600 V, 1.7 A model power supply
For lowest noise performance, make connections to the J2 connector with either
2
individually or group shielded 18-22 AWG (0.3-0.8 mm
) wire. Maintain the shield
to within 1.5in. (40 mm) of the end of each wire. Strip 0.26.in (6.5 mm) of insulation,
insert into the correct terminal, and tighten the wire clamp. You must ground the
shield(s) to the power supply chassis with a connection less than 1.5.in (40 mm)
long.
