Keysight E3630A DC Power Supply

Overview

The Keysight E3630A is a compact triple-output DC power supply designed for benchtop applications requiring multiple independent voltage and current sources. With outputs of 0–6V/2.5A, 0–20V/0.5A, and 0–20V/0.5A in a space-saving form factor, it delivers stable, low-noise power with excellent load and line regulation suitable for a wide range of laboratory and manufacturing test requirements.

Key Features

• Three independent outputs: 0–6V/2.5A, +20V/0.5A, and –20V/0.5A (35W max total)
• Auto-tracking feature synchronizes positive and negative 20V outputs to within 1%
• Exceptionally low noise: 350 µVrms (20 Hz–20 MHz) with 1.5 mV peak-to-peak ripple
• Outstanding load and line regulation better than 0.01% plus 2 mV
• Simple front-panel control with intuitive knobs for voltage and current adjustment
• Separate digital meters for simultaneous voltage and current monitoring
• Meter resolution of 10 mV for voltage and 10 mA for current
• Smooth turn-on and turn-off without power spikes
• Short-circuit protection on all outputs prevents damage from accidental connection errors
• Common mode current less than 1 µA for precision measurement setups

Applications

• Benchtop circuit development and breadboarding
• Symmetric dual-rail power for analog and mixed-signal circuits
• Low-power device testing and characterization
• Laboratory prototyping with multiple independent supply requirements
• Manufacturing test stations requiring compact multi-output power
