Description
EX3C3 180kVA Three-Phase Online UPS
The DAXIN ENERGY EX3C3 180kVA online UPS is engineered for large-scale critical power backup applications that require reliable three-phase power, high efficiency and stable system operation. Its double-conversion online topology helps isolate sensitive equipment from grid fluctuation, voltage instability, frequency variation, harmonic interference and unexpected power interruptions.
Key Features
High-Reliability Online Double-Conversion Design
- True online double-conversion topology delivers clean sine wave output for critical loads.
- Output frequency tracking, phase locking, voltage regulation and noise filtering reduce the impact of unstable grid power.
- Advanced modular dual-CPU control improves system reliability and operating stability.
- Wide AC input voltage range helps reduce unnecessary battery discharge in poor power environments.
- DC start function allows the UPS to start directly from battery when utility power is unavailable.
High Efficiency and Grid-Friendly Performance
- Advanced PFC technology keeps the input power factor close to 1.
- Input harmonic filter design helps reduce feedback pollution to the utility grid.
- Input and output harmonic filters minimize harmonic interference caused by the UPS system.
- High-frequency filtering and synchronization technology improves compatibility with generator power.
Complete Protection Functions
- Output overload protection.
- Output short-circuit protection.
- Inverter over-temperature protection.
- Battery low-voltage warning protection.
- Battery overcharge protection.
- Manual maintenance bypass switch supports easier maintenance without interrupting load power.
LCD Display and Intelligent Management
- LCD display shows UPS operating status, system parameters and alarm information in real time.
- RS232 / RS485 communication interfaces support local monitoring and system integration.
- Optional SNMP network adapter enables remote UPS monitoring and centralized power management.
- Compatible with intelligent UPS monitoring software for clear visibility of operating data.
Optional Intelligent Battery Monitoring Module
- Supports single battery detection and monitoring.
- Provides over-voltage, under-voltage and voltage difference alarm functions.
- Battery fault information can be displayed on the screen to help administrators respond quickly.
Strong Environmental Adaptability
The circuit boards are installed in a fully enclosed structure and treated with conformal coating, improving reliability in harsh environments such as tunnels, plazas, industrial sites and infrastructure facilities.
Typical Applications
- Large data centers and server rooms
- Industrial automation and manufacturing facilities
- Telecom core equipment rooms
- Hospitals and medical systems
- Transportation infrastructure and tunnel projects
- Commercial buildings and large office parks
- Emergency backup power systems
