General Information

Introduction

This chapter contains a general description of your power supply, as well as its performance specifications. Information about options, accessories, and GP-IB cables is also provided. This manual describes all five models in the Agilent 6621A- 6624A, and 6627A power supply family. Unless stated otherwise, the information in this manual applies to all of these models. Information that is specific to one model only is identified as such in this manual.

Safety Considerations

This product is a Safety Class 1 instrument, which means that it is provided with a protective earth terminal. This terminal must be connected to a power source that has a 3-wire ground receptacle. Review the instrument and this manual for safety markings and instructions before operation. Refer to the Safety Summary page at the beginning of this manual for a summary of general safety information. Safety information for specific procedures is located at appropriate places in this manual.

Instrument and Manual Identification

Agilent Technologies power supplies are identified by a two-part serial number, i.e. 2601A-00101. The first part of the serial number (the prefix) is a number/letter combination that denotes either the date of manufacture or the date of a significant design change. It also indicates the country of origin. (Starting at 1960, 26 = 1986; 01 = the first week of the year; A = U.S.A.) The second part of the serial number is a different sequential number assigned to each instrument starting with 00101.

If the serial number prefix on your power supply differs from that shown on the title page of this manual, a yellow Manual Changes sheet that is supplied with this manual explains the difference between your instrument and the instrument described by this manual. The change sheet can also contain information for correcting errors in the manual.

Options

Options 100,120, 220, and 240 simply determine which line voltage is selected at the factory. For information about changing the line voltage setting, see Line Voltage Conversion, page 28.

Option 750 consists of a fault indicator (FLT) and remote inhibit (INH) circuit and relay control, which provide additional shutdown protection should either the GP-IB and/or controller fail. This Option is described in a separate document entitled, "Appendix E Option 750 Operating Instructions for the Multiple Output Linear System DC Power Supply, Agilent Models 6621A, 6622A, 6623A, 6624A, and 6627A (Agilent P/N 5957-6372).
