Feixiangda MZT3080 Three-Phase Online UPS is a professional-grade uninterruptible power system rated at 80KVA/64KW. It adopts a double conversion online design, meaning the rectifier and inverter always operate, providing the cleanest and most stable sine wave power to the load, unaffected by any grid fluctuations or interference.
This product belongs to the MZT3000 series and is a 3-phase input, 3-phase output power frequency UPS. Its core advantages include:
Power Range: 80KVA / 64KW
Operation Mode: Double Conversion Online
Phases: 3 Phase Input + N + G / 3 Phase Output + N + G
Rated Voltage: 380VAC ± 1% (Steady-state load)
Efficiency: 95% (Normal Mode) / 98% (ECO Mode)
Cooling Method: Forced Ventilation (Temperature Control)
The MZT3080 Three-Phase Online UPS operates based on double conversion online technology:
Normal Mode: When mains power is normal, AC input is converted to DC by the rectifier to power the inverter and battery charger. The inverter then converts DC back to clean, stable AC for the load. In this mode, the load is powered by the inverter (via rectifier), completely isolating mains fluctuations and interference.
Battery Mode: When mains fails or is out of range, the rectifier stops working. The battery provides stable AC power to the load via the inverter, achieving zero switching time backup power supply.
Static Bypass Mode: When the inverter fails due to overload or fault, the dual static switches transfer the load to bypass power within 0ms, ensuring uninterrupted operation. Switching time is 0ms when synchronized with the grid and less than 4ms when unsynchronized.
ECO Mode: When grid quality is good, the UPS can be set to ECO mode. In this mode, the load is directly powered by the bypass line, while the rectifier and inverter are in standby. System efficiency reaches 98% or more. Only when the mains is abnormal will it seamlessly switch to inverter power.
