Jenaer ECOBRAX-200 Power Supply Unit

The Jenaer ECOBRAX-200 is a dedicated power supply unit engineered to drive one or more servo amplifiers in industrial and commercial environments. It delivers stable, regulated DC output with selectable input voltage configurations and integrated thermal management via an internal brake chopper. The unit accepts either single-phase or three-phase AC supply and provides configurable chopper voltage modes to accommodate diverse servo system requirements.
