AL3000R Series

Fast Bidirectional DC Power Supply, 5kW to 4MW

The AL3000R is a cost-effective, bidirectional DC power supply that delivers clean, efficient output while recovering energy from the load, returning it to the grid. These fully integrated units are available from 5kW–500kW (up to 4MW parallel), 10-1200V. With flexible modes, and automation-ready controls, it’s ideal for battery testing, EV regenerative braking, and dynamic industrial or power electronics applications.

Regenerative High Power DC Power Supply

Regenerative DC Power Supplies with Robust Topology

Using an isolation dual back-to-back full bridge topology, the AL3000 provides efficient and reliable solid state power conversion in non-regenerative mode. A regenerative version - AL3000R - is available as well.

The AL3000 is available in either standard version (max current available at max voltage) or in Constant Power version using a more flexible range where higher output current is available at lower voltage settings. This is illustrated in the diagram to the right.

Precision Front Panel Controls

Multi-turn potentiometers provide precision control over voltage and current set points. Settings can be locked so no accidental adjustment can be made.

Two large LED Segment displays provide continuous readouts of voltage and current to the load.

User-Friendly AL Manager Software

Intuitive Windows based AM Manager control software turns any PC into a remote operator console. The AM Manager software provided a higher level of power supply control than available from the front panel.
