3-Phase True Online Double-Conversion UPS – High-Frequency Design for Voltage Stabilization
   
  Product Introduction / Introduction
   High-Reliability Design
   	- True Double-Conversion Online Technology delivers frequency synchronization, phase locking, voltage stabilization, and noise filtering - completely isolating loads from grid fluctuations. Pure sine wave output provides ultimate protection for sensitive equipment.
- Dual-CPU Redundant Control System ensures maximum operational reliability and stability while maintaining optimal efficiency.
- Smart Adaptive Charging with CPU-controlled current regulation based on battery capacity.
- Advanced Input Filtering complies with IEEE/EN standards, minimizing feedback pollution to the utility grid.
- Active PFC Technology maintains near-unity input power factor (≈1) across all load and voltage conditions.
- Wide Input Voltage Range (380VAC ±25%) reduces battery cycling in poor power environments.
- Generator-Friendly Design with high-speed synchronization and soft-start capability (requires only 2:1 generator sizing).
- Comprehensive Harmonic Mitigation with input/output filters to minimize THDi.
- DC Cold-Start Function for emergency operation without AC input.
  Comprehensive Protection System
   	- Multi-Layer Safeguards: Output overload/short-circuit protection, inverter overtemperature shutdown, battery undervoltage/overcharge protection.
- Maintenance Bypass Switch enables seamless transition to utility power for uninterrupted maintenance.
 
  Intelligent Monitoring & Control
   	- LCD Interface provides real-time status monitoring and parameter display.
- Remote Management via RS232/RS485, SNMP, and monitoring software.
- Optional Battery Monitoring Module with per-cell voltage detection and alarm functions (over/under voltage, imbalance).

   
  Rugged Construction
   	- Fully-Sealed Enclosure with conformal coating (dust/moisture/corrosion protection) for harsh environments (tunnels, outdoor installations).
