Introduction

This chapter contains instructions for checking and mounting your power supply, connecting your supply to ac power, converting it from one line voltage to another, and connecting the GP-IB cable.

The power supply generates operating magnetic fields which may affect the operation of other instruments. If your instrument is susceptible to magnetic fields, do not locate it in the immediate vicinity of the power supply. Typically, at three inches from the power supply, the electromagnetic field is less than 5 gauss.

Initial Inspection

Your instrument was thoroughly inspected and tested before it left the factory. As soon as you receive it, remove the power supply from its packing case and check to make sure it has not been damaged in shipment. Check that there are no broken connectors or keys, and that the cabinet and panel surfaces are free from dents and scratches. Check the rear panel terminal blocks and front panel display for any cracks. If damage is found, you should file a claim with the carrier immediately and notify the Agilent Technologies Sales and Service office nearest you.

Chapter 3 of this manual includes an electrical turn-on check-out procedure which, when carried out successfully, will give you a high level of confidence that the power supply is operating in accordance with its specifications. Detailed electrical checks complete with verification procedures are included in the Service Manual.

Keep the original packing materials for the carrier’s inspection if there was damage, or in case any equipment has to be returned to Agilent Technologies. Warranty information is printed on the inside cover of this manual. Remember to send a detailed description of the failure and symptoms when returning the power supply for service. Your Agilent Technologies Sales and Service office will furnish the address of the nearest service office to which the instrument can be shipped.

Location and Cooling

Your power supply can operate without loss of performance within the temperature range of 0 to 55 ° C (measured at the fan intake). The fan, located at the rear of the unit, cools the supply by drawing air in through the openings on the rear panel and exhausting it through openings on the sides. Using Agilent Technologies rack mount kits will not impede the flow of air.

Because the power supply is fan cooled, it must be installed in a location that allows sufficient space at the rear and the sides for adequate circulation of air. Either side may be restricted to have as little as 1 inch (25 mm) space.

Figure 2-1 gives the dimensions of the power supply cabinet. These dimensions apply to both models. The cabinet has plastic feet that are shaped to ensure self-alignment when stacked with other Agilent Technologies System II cabinets. The feet may be removed for rack mounting.

The power supply can be mounted in a standard 19 inch rack panel or enclosure. Rack mounting accessories for this unit are listed under options (page 11) of Chapter 1. Complete installation instructions are included with each rack mounting kit. Instrument support rails are required for non-stationary installations. These are normally supplied with the cabinet and are not included with the rack mounting kits.

The Agilent 6626A, on the other hand, offers dual output capabilities with higher specifications. Each of its outputs can be adjusted from 0 to 25 V and delivers up to 3 A, providing enhanced flexibility for designers and engineers working with various devices. Additionally, the 6626A's compact size and lightweight design make it easy to integrate into test setups without occupying excessive space.

For applications that require comprehensive monitoring, the Agilent 6625A provides a unique solution with its built-in digital voltmeter (DVM). This power supply comes with two 0 to 25 V outputs, both capable of 3 A. The integrated DVM allows real-time measurement and displays voltage and current values, ensuring accurate readings during experimentation and testing.

Lastly, the Agilent 6629A is designed for high-performance applications, providing up to four outputs, including two adjustable outputs that can be set between 0 to 35 V and deliver 5 A each. This model is particularly suited for environments where multiple devices need to be powered simultaneously with varying voltage requirements.

All four models come equipped with key features including ease of programming, precision regulation, and superior load transient response. They employ advanced technologies like low-noise operation and excellent line regulation, ensuring stable performance under varying load conditions. Additionally, safety features such as overvoltage protection, current limiting, and rapid recovery from overloads guarantee reliable operation.

In summary, Agilent's 6628A, 6626A, 6625A, and 6629A power supplies provide versatile, precise, and reliable solutions for all electronic testing needs. Their characteristics and dedicated functionalities make them indispensable tools for engineers, researchers, and developers across numerous fields. Whether it's for prototyping, testing, or production, these power supplies deliver the quality and performance that professionals expect from Agilent Technologies.
