Majestic Transformer Company was established in 1942 as a rewinding house for various radio transformers and chokes.
Today all our business is in the design and manufacture of new components.
We hold extensive stocks of our base materials allowing us to respond quickly to your
requirements.
We are able to supply a wide range of:
- Single phase transformers up to 32kVA
- Three phase transformers up to 125kVA
- Auto transformers up to 500kVA
- Transformer rectifier units up to 100kVA
- High frequency transformers
- Audio output transformers
- Inductors and smoothing chokes
Our sales staff are happy to discuss your problems and offer a customised solution.
Recent developments include a 100kVA shore supply unit to allow connection from most worldwide voltages into the ships supply.
The unit was designed and manufactured to meet DNV marine regulations and BS EN 60076.
| We pride ourself on our ability to build a quality product.
To this end our QA system is externally approved to the ISO 9001: 2000 standard. |
|
Our customer list includes:
- BAE Systems
- BOC Edwards
- De La Rue
- Various Universities
- Marshall Specialist Vehicles
- MoD
- Hamworthy Combustion
- Vosper Thornycroft
| Audio Transformers & Chokes
We are able to design & manufacture a wide range of mains and output transformers and also smoothing chokes.
These items are prepared to match exactly the individual requirements of our customers.
Units can be finished fully shrouded (as picture right) for top chassis mounting or half shrouded for drop through chassis mounting.
The audio mains transformers have an earthed interwinding screen and can also be fitted with an external copper 'Q' band.
Other special finishes can be accommodated on request subject to quantity requirements.
We hold a comprehensive range of details relating to Leak, Quad, Mullard and many others and can manufacture new components to
'original' specifications. |

Open Frame Control Transformers Single Phase
Typical applications are motor control, machine tool control, control panels, alarm systems, distribution boards etc.
The transformers are supplied as open types with universal frames for vertical or horizontal mounting and either terminal blocks or brass stud connections.
Virtually any combination of voltage and current, at any frequency, can be supplied on both primary and secondary.
In addition, multiple primary and secondary windings can be accommodated. Complex or high voltage windings may require a larger frame size to be used to accommodate the windings.
Transformers in this range can also have fuses fitted on the top panel.
| Open Frame Control Transformers Three Phase
Typical applications are motor control, machine tool control, control panels, machine voltage conversion, distribution boards etc.
The transformers are supplied as open types with universal frames for vertical or horizontal mounting and either terminal blocks or brass stud connections.
Virtually any combination of voltage and current, at 50Hz, 60Hz or 400Hz, can be supplied on both primary and secondary.
In addition, multiple primary and secondary windings can be accommodated.
Complex or high voltage windings may require a larger frame size to be used to accommodate the
windings. |
Industrial Cased Transformers Single Phase
Our transformers in this range are suitably protected by a sheet metal case.
They are normally wall mountable up to 6kVA and floor standing above this rating, but a portable style is also available.
Our standard cases are IP33 but we can supply up to IP66 if required.
Many requirements are for low voltage tools or lighting working at 24V or 110V to be fed from mains supplies of 230V or 400V.
The above voltages are not exclusive and other inputs and outputs can be accommodated on request.
We can manufacture up to 6kV at a few milliAmps or a few volts at up to 6000A.
All our isolation transformers incorporate an electrostatic screen between the primary and secondary windings and are built in compliance with the latest European standards.
Other worldwide standards, e.g. UL, CSA can also be met. In addition, isolation from the supply may not be required, and in this instance an Auto Wound transformer may be considered to economise on size and cost.
| Industrial Cased Transformers Three Phase
Our transformers in this range are suitably protected by a sheet metal case.
They are normally wall mountable up to 2250VA and floor standing above this rating.
Many requirements are for isolation and/or conversion of three phase machines, or creation of a neutral where none is available.
Our standard cases are IP33 but we can supply up to IP66 if required.
All our isolation transformers incorporate an electrostatic screen between the primary and secondary windings and are built in compliance with the latest European standards.
Other worldwide standards, e.g. UL, CSA can also be met. In addition, isolation from the main supply may not be required, and in this instance an Auto Wound transformer may be considered to economise on size and cost.
Open Frame Miniature Transformers
The trend to smaller power supplies necessitates compact, low cost transformers with pcb mounting without sacrificing quality.
By using ex stock materials, we are able to offer short delivery times, even on small batches of custom built transformers. |
|
Listed below are several typical sizes of standard 50/60Hz laminated transformers.
Sizes quoted are for pcb mounting style. Some sizes are also available with
'U' clamp fixing or Universal Frames.
We can manufacture and test in accordance with the requirements of any international specification.
| High Frequency Transformers & Chokes
We can offer the full range of ferrite cored transformers and inductors utilising the Philips,
Siemens, Thompson or MMG-Neosid ranges of materials. Delivery lead times are dependant on supplier stocks, however we are pleased to hold material stocks for regular items.
Auto Transformers For Use With American Equipment |
|
Our transformers for this application are AUTO-WOUND with a secondary voltage of 110
- 120V and will suit most American domestic appliances.
The transformers are enclosed in portable silver grey cases with standard American socket outlets and UK standard cable & plug input, (other European plugs available to order).
All units are fused on the input winding. All units have rubber feet and those rated 500VA and above have a carrying handle for convenience.
| The input voltage is 230V 50Hz and the ratings listed below are continuous.
Other ratings can be supplied on request.
Power Supplies
Custom built power supplies can be designed and manufactured to your exact requirements.
They can be single phase or three phase input, and AC or DC output. The output can be fixed voltage or variable voltage: variable output may be adjustable in fixed steps or be continuously variable.
The
output(s) can range from a few volts at several thousand amps to several thousand volts at a few milliamps. |
