DC Source and Load, Bidirectional, Regenerative, Compact High-Performance Platform

The IT-M3900B Series combines four product categories: DC power supplies, bidirectional power supplies, regenerative power systems, and electronic loads. With high power density in only 1U height, the series delivers maximum performance in minimal space. It is ideally suited for compact test systems in development, quality assurance, and production.

High Efficiency and Operational Safety

The units are designed for demanding test and measurement applications. They feature high energy efficiency, fast response times, and stable regulation even under load changes. The robust design ensures reliable continuous operation and reproducible measurement results in industrial environments.

IT-M3900B Series – Source and Load in One System

The regenerative energy system of the IT-M3900B Series integrates a DC source and a regenerative electronic load in one device. With one-button switching, users can easily switch between source and load modes. This makes the system highly versatile for battery testing, energy storage evaluation, automotive applications, as well as green energy and ATE systems.

Easily Scalable and Integrable

Thanks to its modular architecture, the series can be seamlessly integrated into existing test systems. The compact design minimizes rack space, while master-slave functions and parallel configurations allow flexible power scaling. This simplifies service, maintenance, and system expansion in test setups.
