Bidirectional Programmable AC Power Supply | A2000 Series

Kewell A2000 Series
Bidirectional Programmable AC Power Supply

Bidirectional AC Power Supply with Regenerative Grid Feedback
The Kewell A2000 Series combines bidirectional capability, programmable control, and state-of-the-art SiC semiconductor technology in a compact, modular design.
These bidirectional AC sources enable precise energy flow in both directions, support regenerative grid feedback for maximum efficiency, and can be flexibly configured via powerful software.
With fast dynamic response and excellent energy efficiency, the A2000 Series is ideal for demanding AC test applications on test benches in R&D, validation, and industrial production.

Flexible Modular Architecture for Diverse Power Requirements
Thanks to its scalable, modular architecture, the A2000 Series adapts optimally to a wide range of power demands.
It supports built-in standard waveforms, creation and editing of complex waveforms, and precise injection of harmonics and interharmonics.

Realistic Simulation of Complex Loads
The A2000 Series enables realistic simulation of RLC loads and offers a wide range of additional functions,
delivering repeatable, reliable, and precise test results—even under the most demanding test conditions.

Setting New Benchmarks in Modern AC Test Systems
Combining versatility, innovative technology, and long-term reliability, the Kewell A2000 Series sets new standards for modern AC test systems.
Available in two versions—Normal (NG) and Pro (PG)—it is the ideal solution for industrial test benches, quality assurance, and high-power test environments.
