Initial Conditions

Immediately after power on from the factory, the power supply automatically undergoes a self-test and sets all parameters to the values contained in Table 5-3. The values in the first part of the table come from storage register 0 and were stored at the factory. They will remain until STO 0 is used to change settings of the power on state. When the power supply is again turned on, it will initialize its outputs to the values in storage register 0.

Power Supply Commands

This section discusses the commands which you will use to program the supply’s voltage and current, protection circuits, and enhanced features like storage and recall registers, and reprogramming delay. When programming, you should be aware that the current, voltage and overvoltage ranges for each output of your supply may differ. Table 5-1 shows these values for the power supply. If you send values out of these ranges, you will get a number range error. A summary of all commands appears in Appendix C.

The output voltage of some output channels exceeds the safe operating limit of 42.2 V. To avoid any electrical shock, program the voltage to zero volts or turn off ac input power before changing any rear panel connections. Make certain all straps are properly connected, terminal block screws are securely tightened and terminal block covers are replaced before reapplying power.

Voltage Programming

To program voltage, send the output channel and the programmed value. In the example below, output l is programmed to 5 V.

VSET 1,5

The values you send must always be volts. For example if you want to program 450 millivolts, convert to volts and then send the command:

The Agilent 6628A is a triple-output power supply, featuring two 0 to 20 V outputs capable of delivering up to 3 A each, along with a 5 V output that can supply 5 A. This combination is perfect for supplying power to devices that require multiple supply voltages simultaneously, making it an excellent choice for testing and development purposes.

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.
