Keysight E36313A DC Power Supply
The Keysight E36313A is an advanced 160 W triple-output programmable DC power supply featuring three electrically isolated channels: 0–6 V / 10 A, 0–25 V / 2 A, and 0–25 V / 2 A. Engineered for sensitive circuit design, IoT development, and aerospace testing, it offers an ultra-low noise floor (<350 µVrms), µA-level low-current readback resolution, built-in data logging, and front/rear 4-wire remote sensing.
Features & Benefits
-
3 Independent Isolated Outputs (160 W Total): Supplies 6 V / 10 A (CH1), 25 V / 2 A (CH2), and 25 V / 2 A (CH3) with total channel-to-channel isolation.
-
Ultra-Low Ripple & Noise (<350 µVrms / 2 mVpp): Pure linear output eliminates switching artifacts, ensuring reliable performance when testing sensitive circuits.
-
Low Current Range with Microamp Precision: Accurately measures low-power standby currents down to microamp levels, ideal for battery-operated IoT and wearable devices.
-
Built-in Scope Mode & Data Logging: Simultaneously logs voltage and current over time directly to an internal memory or external USB drive without needing an external PC.
-
Auto Series / Parallel Internal Relays: Seamlessly doubles voltage (50 V) or current (4 A) on Channels 2 and 3 through menu commands without external cabling.
-
4-Wire Remote Sense on All Channels: Compensates for lead resistance voltage drops using front and rear sense terminals to deliver exact programmed voltages to the load.
Description
Interfaces and Control
- Standard Interfaces: USB and LAN (LXI)
- Optional Interface: GPIB
- Programming: SCPI commands supported for automated control
- Front Panel: 4.3-inch color LCD display showing all three channels simultaneously, color-coded channels, individual knobs for voltage/current, and keypad for quick adjustments
Applications
- Ideal for bench testing, power conversion systems, motor drivers, and inverter testing
- Suitable for precision electronics requiring low noise and stable outputs
- Supports automated test setups with programmable sequences and SCPI commands
Additional Features
- Low acoustic noise for lab environments
- Fast command processing (<10 ms)
- Compact benchtop design with intuitive user interface for productivity
- Software Support: Compatible with Keysight BenchVue for PC-based control and monitoring
Designed to replace industry classics like the E3631A with modern benchtop capabilities, the Keysight E36313A sets the benchmark for clean, quiet, and precise laboratory DC power. Its linear, low-noise power architecture delivers an ultra-clean output with ripple and noise under 350 µVrms / 2 mVpp, ensuring sensitive RF, analog, and mixed-signal devices operate without supply-induced anomalies. With three fully isolated channels, engineers can configure independent grounds, or easily combine channels internally in series (up to 50 V) or parallel (up to 4 A) via the front-panel menu without external jumpers.
