Voltage regulation problems account for more than 90% of the power quality problems seen at most sites. The MODERN Voltage regulators provide protection against mains power sags, surges and brownouts. It is ideal for geographical regions that are subject to inconsistencies in the mains supply, such as Africa, Asia and certain parts of Europe.


Each regulator has a wide input voltage tolerance, and has been designed to provide the ultimate reliability in hostile environments, where the quality of the mains supply cannot be guaranteed.


We are Manufacturer which specialized in Servo Voltage Stabilizer, Uninterruptible Power Supply (UPS), Active Power Filter, etc for nearly 40 years. And be vendor of Mitsubishi Elevator in East Africa, GE, Emerson.




Broadcast:Regulation for broadcast transmitter sites and studios.


COMMERCIAL: High-rise building, elevator control, large A/C chillers, lighting, and other sensitive critical systems.


INDUSTRIAL: Industrial automation, process control, CNC, factory robotics, heavy load machinery.


MEDICAL: X-ray, CT scanner, MRI system, Radiation therapy machine, other medical imaging equipments.


TELECOM: Mobile base stations, exchanges stations, control centers and transmission relay stations, .
