Description Mercury 30kva Online UPS Inverter 3 Phase (384v) The Mercury 30Kva Online UPS Inverter 3 Phase In and Out was designed from the ground up to provide the most reliable on-demand backup power available. If you want the ultimate protection for your mission-critical applications the Mercury transformer-based UPS Inverter series offers the best quality-price fit, giving you the opportunity to acquire high-performance power backup systems at the best market price. ■ Online double conversionOnline Double Conversion design helps to output a pure sine wave, which is immune from the UPS input, so that the load can run steadily.UPS transfers among different working mode without output interruption, thereby powering the load uninterruptedly. ■ Full DSP controlFull DSP Control avoids the risks caused by analog devices failure and makes the control system more stable and reliable. ■ High power factorThe output power factor up to 0.9 better matches the load.The input power fa4or 0.98 with filter helps to improve the efficiency, reduce the harmonic pollution to the Grid and lower the UPS running cost. ■ Wide input adaptabilityThe range of AC input voltage is (380Va/ 400Vac/415Vac) (—25%/ 20%), minimizing transfer to battery mode, thereby greatly prolonging the battery life. Wide input frequency ranging from 45Hz to 65Hz, ensures the stability of UPS while a generator isconnected. ■ Optimized battery management Intelligent battery management system and advanced battery auto float/boost charge technology reduces the frequency of battery maintenance greatly improves battery efficiency and extends battery life.Battery discharge time prediction: the system will display the backup time of the battery calculated by discharge current and voltage.Battery self—test: the battery is automatically tested at regular intervals Flexible battery configuration ranging from 360—480VDC. ■ N X parallel redundancyN X parallel redundant design, up to 6 units available, makes the configuration more flexible. Any unit in the parallel system fails, the faulty one will automatically cut off the output, and the the load will be powered by the remained units.It is easy to configure the parallel system just by connecting the parallel cables and doing proper settings.Non—fixed Master-Slave relationship: Among several UPS in parallel, the unit that startup first is the Master UPS, the others are Slave. The master and slave may be exchanged. ■ Strong overload capability 110%/125%/150% overload for 60min/10min/1min. ■ Power walk-inSpecially designed power walk-in function, in which rectifier of each unit in parallel the system will be turned on in sequence at intervals to avoid the sudden load on the generator, thereby reducing the cost of the generator. ■ Generator modeSet the maximum output power of the generator when a smaller one than needed is employed to extend the battery duration time. In this case, the load is supplied by both the generator and battery. ■ LBS synchronizationSynchronize the output of the two independent UPS systems (simple unit or parallel) even when the two systems are operating on different modes (bypass/inverter) or on battery. ■ Multi-protectionSelf—diagnosis function will take place before the start-up for safety. Multi-protection: AC input under/over-voltage, overload, short—circuit, over—current, over bus voltage, over-temperature, fan failure, auxiliary power failure, battery under-voltage, battery overcharge and so on. ■ EPO functionA concave red EPO button with a transparent cover is embodied in the LCD control panel for emergency power off.
