900 EX Power Bridge
Increase your test capacity.
The 900 EX Power Bridge delivers a straight forward path to higher voltage testing by intelligently pairing two 900EX systems – providing expanded performance without introducing complexity to control, calibration, or service workflows. It is the ideal solution for teams looking to extend test capability while maintaining full confidence in their existing infrastructure.
Benefits of the 900 EX Power Bridge
This integrated solution delivers expanded test capability by scaling capacity up to 1500V / 500 kW, enabling support for higher-voltage battery systems and next-generation energy storage architectures. At the same time, it preserves standalone 900 EX operation, with each unit continuing to function exactly as it does independently, without any changes to behavior, performance characteristics, or operating logic. It also introduces no new calibration or service requirements, as standard 900 EX calibration and maintenance procedures still apply, eliminating the need for additional tools, processes, or training. Finally, the solution offers seamless CAN-based control, remaining fully compatible with the standard 900 EX CAN interface and allowing existing control software to operate automatically when configured with the Power Bridge.
