GENERAL WARNINGS AND CAUTIONS

HIGH ENERGY AND HIGH VOLTAGE WARNINGS

Exercise caution when using and servicing 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 40V. Filter capacitors store potentially dangerous energy for some time after power is removed.

OPERATING AND SERVICE PRECAUTIONS

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.

OPERATING MANUAL FEATURES AND SPECIFICATIONS

1. FEATURES AND SPECIFICATIONS

1.1 Description

This series of power supplies provides low noise, precisely regulated, variable DC output at 2800 Watts of output power. Over voltage protection and thermal shutdown are standard. Front panel controls and indicators are extensive. Select from several remote control choices: standard analog programming, standard remote monitoring of output voltage and current; optional isolated programming or readback, and optional GPIB programming or RS-232 control. Use this power supply either on yo ur bench or in a standard 19" rack: the unit occupies only 3.5" (2U) 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 1.1-1 for the list of available models.

OPERATING MANUAL INSTALLATION

2. INSTALLATION

2.1 Introduction

This section provides recommendations and procedures for insp ecting, installing, and testing the power supply. Refer to the front and rear panel diagrams, Figure 2.3-1 and Figure 2.3-2, as necessary.

2.2 Basic Setup Procedure

Table 2.2-1 provides both a summary of the basic setup procedure and an overall view of the subsections in Section 2. Use the procedure as a quick reference if you are familiar with the installation requirements for the power supply. If you want more information, each step in the procedure refers to subsequent sections which contain more details. Execute each step in the sequence given.

Table 2.2-1 Basic Setup Procedure

Step # Description Action Reference

1 Inspection Perform an initial physical inspection of

the supply.

2 Installation Install the supply (bench or rack mount),

ensuring adequate ventilation. 3 Input Power Connect AC input power. Section 2.5 AC Input Power Connection 4 Test Perform functional tests for voltage mode

operation, current mode operation, and

front panel controls. 5 Load Connect the load. Section 2.7 Load Connection 6 Sensing Connect sensing lines. Section 2.8 Local and Remote Sensing

Section 2.3 Inspection, Cleaning, and Packaging

Section 2.4 Location, Mounting, and Ventilation

Section 2.6 Functional Tests

See Section 3. Local Operation for instructions for front panel operation, over voltage and over temperature protection, shutdown, and using multiple supplies. You will find remote programming and monitoring described in Section 4. Remote Operation.

2.3 Inspection, Cleaning, and Packaging

2.3.1 Initial Inspection

When you first receive your unit, perform a quick physical check.

1. Inspect the unit for scratches and cracks, and for broken switches, connectors, and displays. See Figure

2.3-1 and Figure 2.3-2.

2. Have the service technician check the printed circuit board and its components if you suspect internal damage.

If the unit is damaged, save all packing materials and notify the carrier immediately. See packing instructions in Section 2.3.3.
