900 EX Power Bridge High-voltage expansion for advanced battery test applications
The 900 EX Power Bridge seamlessly combines two 900 EX units to expand system capability to up to 1500V and 500kW, enabling higher voltage battery test scenarios while preserving the proven behavior, control, and service module of each individual 900 EX. Solutions overview The 900 EX Power Bridge delivers a straightforward path to higher voltage testing by intelligently pairing two 900 EX 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 infra - structure.
Features: Expanded test capability
Primary application – Designed specifically for battery testing application requiring elevated voltage and power levels Model configuration – Existing 900 EX systems can be retrofitted in the field Operational bandwith – Pulse test frequencies above 10 Hz are not recommended Scalable performance – Expands testing capability while maintaining full confidence in your existing infrastructure
– Scales testing capacity to 1500V / 500kW, supporting higher voltage battery systems and next generation energy storage architectures Preserves standalone 900 EX operation – Each 900 EX continues to operate exactly as it does in standalone mode – No changes in unit behavior, performance characteristics, or operating logic No new calibration or service requirements – Standard 900 EX calibration and service procedures apply – No additional maintenance processes, tools, or training required Seamless CAN based control – Fully compatible with the standard 900 EX CAN interface – Existing CAN control software operates automatically when configured with the Power Bridge
