MST Pro Series 1-3kVA

Double conversion Online (VFI)

MST Pro Series is a range of ON-LINE double Conversion technology UPS with  1.0 output power factor and “zero” transfer time, the load is always powered by the inverter, which supplies true sinusoidal voltage that is free from electrical interference.


MST Pro Series offers high quality power supply with the greatest degree of availability and reliability

MST Pro Series is compact and very convenient for users, especially for basic equipment  such as PC, Workstation, Network centers, Communication equipments, and other critical systems.


Battery expansion is possible to increase the back-up time of the UPS. For longer back-up time, it is available MST Pro “L” version without internal battery but with powerful battery charger
