qWhat are the design life, cycle life and preventive maintenance interval?

a

10-year design life; 6,000 full cycles; over 10 million shallow pulse cycles; MTBF >100,000 hours. Remote inspection every three months; no on-site visits required.
qIs Sidecar expansion supported? What are the performance specifications?

a

Supports Sidecar expansion without a separate battery room. Rated power: 1 MW per unit; peak power: 1.5 MW. Vision’s proprietary LiLic technology combines BBU and CBU capabilities for extended backup and high-frequency pulse smoothing, with over 10 million pulse cycles. Response time <100 μs delivers an orders-of-magnitude improvement over millisecond-level industry benchmarks.
qDoes the fire protection solution meet NFPA/FM/EN standards? How do monitoring and interlocked protection work?

a

Fire monitoring and interlocked breaker tripping logic meet UL and NFPA standards. Pack-level immersion cooling provides electrical insulation and flame retardancy. Temperature, smoke, combustible gas and liquid leak detection signals are sent to the main control cabinet to trigger protective actions.
