CTECHI 110 V High-Voltage LiFePO₄ UPS (1–3 kVA) – Online Double-Conversion, Tower & Rack Version
Detailed Product Features
- Longer Battery Life & Backup – The LiFePO₄ cells provide up to 3× longer lifecycle and extended runtime compared to traditional lead-acid alternatives, significantly reducing maintenance.
- Advanced Battery Management System (BMS) – Equipped with a comprehensive BMS featuring MODBUS (RS485) interface and a dedicated 4-stage charger to ensure battery safety and longevity.
- On-Line Double-Conversion Technology – Offers the highest level of power conditioning by fully isolating load from grid disturbances, ensuring clean, reliable output.
- Flexible Deployment – Configurable as tower or rack (2U) model to suit varying installation environments.
- Wide Input Voltage Range – Stabilizes performance across various input voltages (roughly 60 – 145 VAC), maintaining consistent output even under unstable grid conditions.
- Cold-Start Capability – Can power on directly from the battery even during complete grid failure, enabling critical system initiation during blackout scenarios.
