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.

Section 1. Features and Specifications
Description
This series of power supplies provides low-noise, precisely regulated, variable DC
output at 1200 Watts of output power. Over voltage protection (OVP) and thermal
shutdown are standard. Front panel controls and indicators are extensive. Select from
several remote control choices: standard analog programming, optional isolated
programming or readback, and optional GPIB programming or RS-232 control.
Remote monitoring of output voltage and currents is a standard feature. Use this
power supply either on your bench or in a standard 19 in. (483 mm) rack: the power
supply occupies only 1.75 in. (1 U) of vertical rack space. Designed for continuous
use in standalone or systems applications, this power supply is typically used to
power DC equipment, control magnets, or burn in components. See Table 1.1 for the
list of available models.

Resetting the Switches Before making any changes to the switch settings,
disable the power supply output by pushing the front panel STANDBY switch to its
IN position. This temporarily shuts down the power supply. The front panel S/D
LED turns on. Then use any small, flat-bladed screwdriver to change the switch
settings.
Any of the eight switches on SW1 is OFF (OPEN) when it has been flipped up to
break contact, ON (CLOSED) when flipped down to close contact.
Rear Panel J2

The J2 Programming and Monitoring connector is a 15-terminal wire clamp
connector located on the power supply’s rear panel. See Figure 1.4. The J2 connector
provides access to the following functions:

Making J2 Connections
CAUTION
Do not attempt to bias program/monitor signal return (J2 terminals 5, 7, 9, and
11) relative to the supply output because control ground (J2-3) and the
program/monitor signal returns are at the same potential as the power supply
return in a standard unit. Use the Isolated Programming (ISOL) interface option
to allow control from a programming source at a different potential relative to the
supply’s output.
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.
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 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, 2 A model power
supply.
For most connectors and jumpers, use any suitable wire such as 16 to 24 AWG
stranded wire. For lowest noise performance, use shielded pair wiring of 16 to 24
AWG. Strip wires 0.26 in. (6.5 mm), insert, and tighten the wire clamp.
