Cautions
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.

Safety
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 2800 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 current is a standard feature. Use this power supply either on your bench or in a standard 19 in. (483 mm) rack: the unit occupies only 3.5 in. (2 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 when it has been flipped up to break contact, ON when flipped down to close contact.

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 when using a power supply with a rated output greater than 40 V. Use 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, 4 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. Strip wires 0.26 in. (6.5 mm), insert, and tighten the wire clamp.
