CTECHI 220 V LiFePO₄ UPS (1–3 kVA) – Tower & 2U Rack-Mount, Online Double-Conversion Battery Backup
Detailed Product Features
- Durable LiFePO₄ Battery Technology
- Equipped with 48 V LiFePO₄ batteries, the system offers up to three times longer lifecycle and backup time compared to traditional lead-acid options.
- Online Double-Conversion & Smart BMS
- Offers full-time pure sine wave output with seamless double-conversion UPS functionality. Integrated Battery Management System (BMS) includes a MODBUS (RS-485) interface and a 4-stage charger (constant current, constant voltage, floating, turn-off) for safe and optimized battery charging.
- Versatile Form Factors
- Available as a compact tower model or a space-saving 2U rack-mount option—ideal for different installation needs from small offices to IT cabinets.
- High Efficiency
- Optimized for energy savings in both normal operation (line mode) and battery-supported mode.
- Wide Input Voltage Range & Cold-Start Capability
- Accepts a broad input range and includes cold-start functionality, enabling the UPS to start up and power connected devices even during complete power outages.
