A DC bench power supply is a stand-alone device that provides a stable and adjustable DC voltage and current to power electronic circuits during development, testing, and troubleshooting. Sorensen bench power supplies are ideal for lab benches, offering precise control, low noise, and multiple safety features.

In constant voltage (CV) mode, the power supply maintains a fixed voltage while the current varies based on the load. In constant current (CC) mode, the current is fixed and the voltage adjusts to maintain that current. Sorensen bench power supplies like the XDL and XEL Series support both modes, allowing precise control for sensitive electronics testing.

Sorensen power supplies offer advanced features like linear regulation, PowerFlex™ technology, remote programming, and multi-output configurations. Models like the XDL Series include memory presets and rotary control, while the XPF Series supports high current outputs with dual isolated channels.

Absolutely. While designed for benchtop use, many Sorensen models (like the XEL-P and XPF-DP) include remote programming interfaces and robust protection features, making them suitable for automated test equipment (ATE) and light production testing as well.

Yes. Sorensen programmable DC bench supplies are well-suited for battery charging, simulation, and testing. With features like programmable voltage/current limits, remote sense, and fine control, models like the XPF60-20D and XEL-P can safely simulate battery behaviour or charge batteries under controlled conditions.

Consider the following:

• Voltage and current range needed for your device
• Number of outputs (single, dual, or triple)
• Form factor and available bench space
• Interface requirements (USB, Ethernet, GPIB)
• Noise sensitivity (linear vs. switch-mode) For example, the XPL Series is ideal for compact, low-power needs, while the XPF Series is better for high-current applications.

The XPF Series is ideal for high-current needs, offering up to 20A per output and a total power of 840W. Its PowerFlex™ design allows higher current at lower voltages, making it suitable for demanding test environments.

Linear power supplies, like the XEL and XPL Series, provide low noise and precise output, ideal for sensitive electronics. Switch-mode supplies, like those in the XPF Series, are more efficient and compact, suitable for higher power applications with less concern for noise.

Yes. Models like the XEL-P and XPF-DP include LXI Ethernet, USB, RS-232, and optional GPIB interfaces, making them ideal for integration into ATE systems and remote-controlled test setups.

The XDL Series offers:

• Digitally controlled linear output
• Numeric and rotary control
• Memory for up to 30 setups (triple output)
• Over-voltage and over-current protection
• Remote sense terminals for accurate voltage delivery

The XEL Series includes features like V-Span (voltage range limiting), S-Lock (voltage locking), and Output Enable, allowing users to safely configure voltage/current before activation. These features protect devices under test and improve precision.

Yes. The XPL, XPH, and XEL series offer dual and triple output models with independent, isolated channels. Outputs can be wired in series or parallel for higher voltage or current, and some models include fixed 3.3V/5V outputs.

All models include short-circuit protection, reverse current protection, and over-voltage/current trips. These features ensure safe operation for both the power supply and the device under test.

The XPL Series is designed for compact environments, offering up to 125W in a small footprint. It’s ideal for educational labs, R&D benches, and budget-conscious users needing reliable, low-noise DC power.
