Function Features

• Full digital DSP control for ultra-fast transient response (load step change recovery <2ms)
• Built-in overvoltage, undervoltage, overcurrent, short-circuit, over-temperature, and battery deep-discharge multi-layer protection
• Real-time remote monitoring via industrial SCADA systems; event log storage for 10,000 fault records
• Hot-swap bypass maintenance function: single unit offline maintenance without cutting downstream critical loads
• Intelligent fan speed regulation to reduce noise and extend fan service life
• Harmonic suppression rectifier eliminates grid distortion impact on sensitive industrial control equipment
• Auto battery self-test routine (configurable weekly/monthly cycle) to predict battery failure

Working Principle

1. Normal Grid Mode: AC grid input passes IGBT rectifier to convert stable DC voltage; DC energy charges external battery pack while feeding IGBT inverter to generate pure sine-wave stabilized AC output to loads
2. Grid Failure Mode: Battery pack instantly supplies DC power to inverter; zero transfer time (<10μs) avoids load power interruption
3. ECO Bypass Mode: Grid power directly supplies loads through static bypass switch when grid quality meets threshold; rectifier-inverter standby for fast switchover to save energy
4. Parallel Redundant Operation: Distributed RPA control algorithm synchronizes voltage, phase, and frequency across multiple UPS units; automatic load balancing and faulty unit isolation

Material & Structural Characteristics

• Main Cabinet: 2mm cold-rolled steel plate with epoxy anti-corrosion coating
• Power Semiconductor Module: Silicon carbide SiC IGBT power modules for high efficiency and low heat generation
• Heat Dissipation System: Multi-channel axial flow fans with aluminum alloy heat sink fins
• Control Board: Conformal-coated PCB to resist humidity and dust corrosion
• Busbar: Tinned copper busbars with high-temperature insulation sleeves for high-current transmission

Installation Requirements

1. Install in dedicated power distribution room with ventilation air volume ≥1200m³/h; ambient temperature controlled below 35°C
2. Reserve front maintenance clearance ≥1200mm, rear heat dissipation clearance ≥800mm
3. Equip upstream 100A three-phase molded case circuit breaker with short-circuit protection
4. Separate battery cabinet and UPS main cabinet with fire-resistant cable trenches
5. Connect all protective earth terminals to independent industrial grounding grid (ground resistance ≤1Ω)

Usage Precautions

• Do not operate continuously above 80% rated load for long-term service life optimization
• Avoid installing near corrosive gas, conductive dust, or high-humidity steam environments
• Perform battery capacity test quarterly; replace batteries when discharge capacity drops below 80% rated value
• Disable parallel function before disconnecting any unit from the parallel busbar
• Cut off both grid input and battery DC power before opening cabinet panels for maintenance
