Agilent / Keysight E3633A DC Power Supply

The Keysight E3633A is a 200 W single-output DC power supply with dual-range capability, delivering stable, low-noise power for benchtop and integrated system applications. Two independent output ranges—0 to 8 V at 0 to 20 A, or 0 to 20 V at 0 to 10 A—accommodate diverse test requirements. Exceptional load and line regulation of 0.01% ensure output stability across operating conditions.

– Key Features

Protection circuits include overvoltage and overcurrent protection. The front panel combines a vacuum-fluorescent dual-meter display with intuitive knob control and dedicated keys for resolution selection, voltage/current switching, and output control. Three operating states can be stored and recalled. Voltage and current limits are independently settable.

– Interfaces and Control

GPIB (IEEE-488) and RS-232 connectivity enable remote control. Full SCPI compatibility supports standard command syntax for integration into automated test systems. Front and rear output terminals accommodate both benchtop and rack configurations.

– Physical Design

Ruggedized portable case with non-skid feet. AC mains connection requires a properly grounded three-conductor cable.

– Typical Applications

Device characterization, power-supply testing, integration testing, and laboratory measurement tasks requiring precise, low-noise DC output with programmable control.
