NDT - Non destructive testing

Industrial X-ray demands highly stable and accurate High Voltage Power Supplies. Our power supplies are capable of material analysis, NDT, security checks and industrial probing to name a few. We make miniature DC input modules up to high power X-ray generators that support various filament voltages suitable for continuous operation.


COVID-19 Update from Genvolt
Here at Genvolt, the wellbeing of our employees, their families and our customers remain the most important thing to us. We are very conscious of following government directives and want all our staff to be safe and in turn save lives.

During these extremely difficult times we wanted to re-assure everyone that we are doing our very best and as of 1st April, Genvolt will be operating with only a skeleton crew, to ensure that we are still available for our customers and try our utmost to fulfil your requirements. 

We have always prided ourselves on being a responsive and agile business and are practising social distancing in the workplace and every effort is made to sanitise our working environment, to keep our small team safe.

In the meantime, thank you for your continued support and we wish you all the best and sincerely hope you and your families stay healthy.


Genvolt UK have been manufacturing high voltage power supplies since 1991 and our diverse range offers high voltage power supply solutions that are suitable for a wide variety of applications and performance demands.
Our innovative products offer power supplies with output voltages from as low as 200V to over 300kV. The Genvolt range has typical output power figures from 20W to 24kW.
