Sorensen XDL35-5T DC Linear Power Supply

Overview

The Sorensen XDL35-5T is a triple-output linear DC power supply designed for precision laboratory and test applications. It features two independent main outputs with multiple selectable voltage and current ranges, plus a fully isolated auxiliary output (1.0–5.0V, 3A) for powering logic circuits. Voltage and current control utilizes 16-bit DACs, delivering 1mV resolution and calibration-grade accuracy sufficient for hand-held DMM calibration.

Pure linear technology ensures superior regulation, with output noise below 350µV rms in constant-voltage mode and 20µA rms in constant-current mode. Transient recovery from load pulses is faster than 50µs, making the XDL35-5T ideal for demanding precision applications.
