Agilent/Keysight E3646A

The Agilent/Keysight E3646A is a 60 W dual-output programmable DC power supply engineered for R&D design verification, production testing, and quality assurance. It delivers clean, regulated power with fast transient response and combines benchtop usability with remote programmability. Dual-range outputs provide flexible voltage and current configurations, while standard GPIB and RS-232 interfaces enable system integration and automated test sequences.
