Transokraft 3 N1  

1/2

The analog Transokraft inverters are  designed to secure uninterrupted power supply to critical loads which require an AC voltage supply independent of the mains power and the faults which may occur.
This independent supply avoids interruptions to the connected loads caused by mains power failures, mains voltage deviations or mains frequency deviations, any of which may result in considerable financial costs and physical danger. Over 35 years of experience in nuclear power plant technology helps us to provide the perfect solution to protect your application.
