Majestic Transformer Co recently supplied a number of Variable Transformer Power Supplies for Nottingham University for their newly refurbished Electrical Engineering laboratories.

The units were able to take the standard 3 phase supply and provide two optional variable outputs, one limiting the voltage to SELV limits at 50V and the other allowing access to the full supply voltage once the students had gained the necessary clearance. The output voltage range was switched via a keylock switch ensuring that no unauthorised changing of voltage range could occur. The output voltage was controlled by use of a motor driven variable transformer with push button control. Output voltage, current, power factor etc can be monitored by means of a multi-function LED display.


The university originally approached Majestic Transformer Co to supply just the isolation transformers necessary for the project, but were pleased to be able to allocate the complete power supply project to them once they realised the company could produce the complete units within their budget and within their time scale.

Majestic Transformer Co have been manufacturing single phase transformers and three phase transformers, along with chokes and transformer rectifier power supplies for over 65 years and have a wealth of experience in manufacturing custom built transformers to meet many varied specifications and standards, from basic commercial & marine, to medical, railways & defence.
