Description

Agilent E3631A: Triple-output programmable DC power supply for accurate measurements

The Agilent E3631A programmable DC power supply is a versatile bench instrument that meets the needs of engineers in research, design and production. With three independent outputs and a total power of 80 W, it can power different circuits simultaneously without cross interference. The main output offers a range of 0 to 6 V with a maximum current of 5 A, while the other two channels deliver +25 V/1 A and -25 V/1 A respectively. Electrical isolation between the 6 V output and the ±25 V outputs minimises interference and ensures a clean and stable power supply for sensitive circuits.

With 0.01% line and load regulation and low noise (350 μVrms), the E3631A guarantees continuous and reliable power supply, even with variations in input voltage or load. This makes it ideal for applications requiring high precision, such as concept validation, production testing or quality verification. Its fast transient response allows signal recovery in less than 50 μs after a sudden load change, which is essential for dynamic testing.

The intuitive user interface, consisting of a rotary knob and quick selection keys, makes it easy to configure the outputs. Settings can be saved and recalled via the built-in non-volatile memory, reducing setup time for repetitive test series. The E3631A also includes an output on/off control that allows the power to be cut instantly.

For users who want automated control, the device comes standard with GPIB and RS-232 interfaces, compatible with SCPI (Standard Commands for Programmable Instruments). This makes it easily programmable from a PC for complex or automated test procedures.

Compact and weighing only 8.2 kg, the E3631A fits easily into tight laboratory spaces or on production benches. Its compliance with international safety standards, quiet operation and mechanical robustness make it a reliable investment for demanding technical environments.
