Overview
The Picotest J2103A Power Stage Isolator is a versatile power supply testing and measurement device. It replaces feedback control circuits to control the power output circuit, enabling accurate power supply plant gain frequency response measurement. This essential tool breaks the control loop of power supplies, facilitating precise open and closed-loop measurements.
Compatible with the OMICRON Lab Bode 100 VNA and other Frequency Response Analysers, the J2103A works with virtually any power circuit requiring feedback control. It supports isolated and non-isolated power sources, switching and linear power supplies, and positive or negative voltage feedback systems.
The J2103A features differential inputs for feedback (Vin) and reference voltage (Vref), eliminating ground reference issues. Its battery-powered operation ensures isolation and portability. It offers flexibility for various power supply designs with a maximum input voltage of ±60V for Vin and ±10V for Vref.
This power stage isolator is invaluable for power supply designers, enabling quick access to hidden or difficult-to-bound parameters. It supports accurate parameter testing for state-space average VRM model development, significantly shortening the design cycle for power supply systems.
