The Agilent/Keysight E36311A is an 80 W triple-output programmable DC power supply engineered for benchtop electronic testing and development. It delivers three isolated outputs with independent voltage and current control: a primary 6 V / 5 A channel and dual ±25 V / 1 A tracking outputs. The unit combines precise regulation (0.01% line and load), ultra-low noise performance (<350 µVrms across all outputs), and real-time monitoring via a 4.3-inch LCD display that shows voltage and current for all three channels simultaneously.
Technical Specifications
Output 1: 0–6 V DC at 0–5 A DC with 0.1% + 5 mV programming accuracy and <350 µVrms / 2 mVp-p ripple.
Outputs 2 & 3: 0–+25 V DC and 0–−25 V DC respectively, each at 0–1 A DC with 0.05% + 20 mV programming accuracy, <350 µVrms / 2 mVp-p ripple, and fixed tracking-only configuration.
Line and load regulation hold 0.01% across all channels. Current ripple measures <2 mA rms on Output 1 and <500 µA rms on Outputs 2 & 3 (20 Hz to 20 MHz). Readback accuracy is 0.1% + 5 mV (Output 1) and 0.05% + 10 mV (Outputs 2 & 3) for voltage; 0.1% + 10 mA and 0.1% + 4 mA respectively for current.
– Key Features
