Sorensen XDL56-4TP Triple Output DC Linear Power Supply

Overview

The Sorensen XDL56-4TP is a triple output DC linear power supply for precision bench testing and equipment calibration. It features two main outputs with multiple voltage and current ranges, plus one auxiliary output for logic circuits. Using pure linear technology, it delivers exceptional regulation, minimal output noise, and fast transient response—making it ideal for critical test applications. The P-suffix model includes built-in GPIB, RS-232, USB, and LAN (LXI-C) interfaces.

Key Features

• Three fully isolated outputs: two main outputs plus auxiliary output
• High precision voltage control with 1 mV resolution
• Multiple voltage and current ranges for flexibility
• Very low output noise: less than 350 µV RMS in CV mode
• Fast transient recovery: better than 50 µs
• Remote or local sense capability for load regulation
• Fully adjustable over-voltage and over-current protection with alarm output
• Up to 30 set-up memories in non-volatile storage
• Built-in GPIB, RS-232, USB, and LAN (LXI-C) interfaces for remote operation
• Three-year warranty

Applications

• Precision bench testing and circuit troubleshooting
• Equipment calibration and certification
• Electronics design and development
