Industrial-grade, transformer-based uninterruptible power supply engineered to provide uncompromised resilience for critical infrastructures. Featuring an advanced IGBT rectifier and built-in galvanic isolation, it guarantees pure sinusoidal power, eliminates utility harmonics, and protects sensitive medical, industrial, and IT loads against severe grid anomalies.
Clean IGBT Rectifier: High 0.99 power factor and < 2.5% THDi prevent utility distortion and eliminate the need for oversized generators.
Generator-Friendly Soft-Start: Controlled ramp-up prevents generator tripping during load transfers.
Parallel Scalability: Connect up to 6 units in decentralized or centralized bypass for N+1 redundancy or capacity expansion.
Expert Battery System (EBS): Extends battery lifespan through managed charging profiles and internal resistance testing.
Smart Remote Connectivity: Supports Modbus RTU/TCP, BACnet/IP, and NET VISION SNMP cards for centralized monitoring.
