Online UPS 10KVA-400KVA

The MF series UPS is digital information, networking online intelligent pure sine wave uninterruptible power supply which is based on reliable, advanced, high efficiency digital analogy hybrid technology UPS system that provides the user with clean computer grade power for continuous operation of his critical load, regardless of any disturbance on the upstream AC power. The system offers many innovative features to give the user maximum reliability and flexibility at the lowest operating cost.

IGBT Rectifier
With Up-to-date IGBT rectifier technology,MF series input PF is more than 0.99 and THDI is less than 3%,therefore it

does not pollute the utility grid and other devices which share the same utility.

Digital Signal Processing
The modular uses the most advanced DSP technology. Thanks to the DSP, MF31/33 output and system parameters are

controlled and maintained conveniently throughout the various modes of operations.

Wide Input Voltage Range
The modular features a wide input voltage range of +15%, -20% at full load under normal conditions. This is extremely

useful in power grids environment as the battery energy is not utilized and can be preserved for more prolonged outages.

Complete protections
With various system protections, such as over voltage ,low voltage ,over current ,overload, short circuit etc….

High Efficiency ECO Mode
In situation where the utility supply is relatively stable the MF31/33 series can be set to energy saving ECO mode. An

efficiency ofgreater than 97% can be achieved. The load is never in danger as the switching is done by high speed solid

state devices.

Intelligent Battery Management
Proper testing, charging, discharging and management of the battery system is a very important aspect of the UPS control

system.In the MF31/33  series UPS, the batteries are constantly monitored by an intelligent battery management algorithm.

Any fault detected in the batteries is immediately reported to the user.

User Friendly Display and Communication
Dual-color LED indicates the status of major modules. The neatly displayed push-buttons give functions such as menu

selection,inverter startup and shutdown, emergency shutdown and alarm. The large LCD graphical display provides an

array of performance parameters,fault information and historical event log that are useful for troubleshooting.
The system provides voltage-free relay contact of common alarms, RS232 & RS485 signals for remote monitoring, and

SNMP(optional) for web-based monitoring. With self-diagnosis and self-protection, audio and visual alarm indications

are available and these alarm notifications can be sent by e-mail or paging to the service personnel.
