20 KVA To 60 KVA Online High Frequency UPS Power Supply 3 Phase Rack Mount
EX3C3 30kVA Three-Phase Online UPS
The DAXIN ENERGY EX3C3 30kVA online UPS is designed for critical power backup applications that require stable, clean and uninterrupted three-phase power. Its online double-conversion topology protects sensitive equipment from voltage fluctuation, frequency variation, harmonic interference, electrical noise and unexpected power interruptions.
Key Features
Reliable Online Double-Conversion Design
- True online double-conversion topology provides clean sine wave output for sensitive equipment.
- Output frequency tracking, phase locking, voltage regulation and noise filtering help reduce the impact of unstable utility power.
- Advanced modular dual-CPU control improves UPS reliability, operating stability and overall system performance.
- Wide AC input voltage range reduces unnecessary battery discharge in unstable power environments.
- DC start function allows the UPS to start directly from battery when utility power is unavailable.
High Input Power Factor and Low Harmonic Interference
- Advanced PFC technology keeps the input power factor close to 1 under different load and utility voltage conditions.
- Input harmonic filter design reduces feedback pollution to the utility grid.
- Input and output harmonic filters help minimize UPS interference with the power system.
- High-frequency filtering and synchronization technology improves generator compatibility.
Complete System Protection
- 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 service while keeping load power supplied through bypass.
LCD Display and Smart Monitoring
- LCD display shows UPS operating status, system parameters and alarm information in real time.
- RS232 / USB communication interfaces support local monitoring and computer communication.
- Optional SNMP network adapter enables remote UPS monitoring and centralized power management.
- Compatible UPS monitoring software provides clear visibility of system operating data.
Optional Intelligent Battery Monitoring
- 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 demanding equipment rooms.
