Fixed and variable DC supplies for on-bench power & testing work

A selection of DC power supply modules are available for the CalBench system. Fixed DC power supplies include 24 V modules for loop powered devices being tested on the bench. Variable DC power supplies provide an adjustable output for supplementing power to applications or general purpose use in troubleshooting and diagnostics.

The selection of DC power supplies range from basic fixed outputs to advanced adjustable modules with multiple features, modes and functions. The variable power supplies are versatile solutions with several types to choose from. These include high accuracy, multi-range modules, dual output versions, high power, and programmable DC supplies.
