Our business is in the design and
manufacture of transformers, chokes and associated power supplies.
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 Transformers:
... Single phase Transformers up to 32kVA
... Three phase Transformers up to 125kVA
... Auto up to 500kVA
... Rectifier units up to 100kVA
... High frequency SMPS
... Audio mains and output
... Inductors and smoothing chokes
... Voltage Stabilisers
We are always happy to discuss your power needs and offer a
Recent developments include a range of oil filled high voltage
transformers for a series of semiconductor test processes. These
units were supplied in an oil bath and manufactured to the
requirements of BS EN 60076. We have also manufactured a 100kVA
isolation transformer for use by Network Rail.
We pride ourselves on our ability to build a quality product. To
this end we operate QA system that is compliant with the ISO 9001:
2008 standard. Our customer

Our product range includes:
Open Frame Control
Typical applications are motor control, machine tool control, control panels,
alarm systems, distribution boards etc. These 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.
Audio Transformers & Chokes
are able to design & manufacture a wide range of mains and output units and also
smoothing chokes for use in audio applications. These items are designed and
manufactured 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 units 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
We hold a comprehensive range of details relating to Leak, Quad, Vox and many
others and can manufacture new components to 'original' specifications.
Industrial Cased Single Phase Transformers
Our products in this range are suitably protected by a sheet metal case. They
are normally wall mountable up to 5kVA 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 10000A.
All our isolation items 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 Three Phase Transformers
in this range are suitably protected by a sheet metal case. They are normally
wall mountable up to 2700VA 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 on the supply. 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 BS EN 61558 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
Transformer Rectifier Power Supplies
Custom built transformer rectifier power supplies can be designed and
manufactured to your exact requirements. They can be single phase or three phase
input, 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.
High Frequency SMPS Transformers & Chokes
We can offer the full range of ferrite cored transformers and inductors
utilising the Ferroxcube, Siemens, Thompson or MMG-Neosid ranges of materials
for use in Switched Mode Power Supplies. Delivery lead times are dependant on
supplier stocks; however we are pleased to hold material stocks for regular
