Sorensen XDL56-4P DC Power Supply

Overview

The Sorensen XDL56-4P is a programmable single-output linear DC power supply designed for automated test systems and remote laboratory environments. The P variant includes GPIB, RS-232, USB, and LAN (LXI-C) interfaces for complete remote control and instrument data readback, enabling seamless integration into ATE systems and networked test labs. Multiple voltage and current ranges optimize resolution and dynamic range for diverse applications. 16-bit DAC precision delivers 1mV voltage resolution and calibration-grade accuracy. Pure linear technology ensures superior regulation, low-noise outputs, and fast transient recovery.

Rear-panel output and sense terminals support simultaneous front and back connectivity for system integration. The unit can be programmed via bus interface with 1mV and 0.1mA resolution, while front-panel operation remains available for standalone use. Non-volatile memory stores up to 50 power configurations for repeatability in production and test environments.
