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.
