Mercury 30kva Online UPS Inverter features
■ Online double conversion
Online 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 control
Full DSP Control avoids the risks caused by analog devices failure and makes the control system more stable and reliable.
■ High power factor
The 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 adaptability
The 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 is
■ 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 redundancy
N+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/
■ Power walk-in
Specially 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 mode
Set 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
■ LBS synchronization
Synchronize 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.
Self—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 function
A concave red EPO button with a transparent cover is embodied in the LCD control panel for emergency power off.
