SIGA enhances Bedfordshire magnetics facility with major investment


SIGA Electronics Ltd, a leading UK manufacturer of high-quality transformers and other wound components in the ETAL Group, today announced an investment in its Sandy, Bedfordshire manufacturing site increasing its manufacturing capacity and broadening the range of magnetic solutions it can offer customers.

SIGA has invested in a larger bobbin winding machine, which can wind heavier gauge wire and copper strip, allowing it to offer customers larger transformers with a higher current carrying capacity and higher power ratings. SIGA has also purchased a Wayne Kerr Precision Magnetics Analyzer ref 3260B, a state of the art instrument which can characterise magnetics components fully under a wide range of circuit conditions. The new instrument enhances the speed and throughput of SIGA’s exemplary quality control, which includes 100% electrical testing of every device followed by a visual check.

Richard Thrussell, General Manager of SIGA Electronics, “We are continually investing in our business to ensure that our equipment is state of the art. The new systems in our manufacturing and final test areas allows us to offer higher power transformers allowing us to expand our production capabilities and increase our customer base. The investment demonstrates the commitment of our new parent company, KAMIC, to SIGA’s business success.”

SIGA occupies a purpose built, 15,000 sq. ft. factory where over 50 employees produce a wide range of high quality transformers and inductors. A custom engineering team is based at the same location. SIGA supplies wound components conforming to international standards, including EN61558, EN60601, and EN60950, and in addition a range of standard and custom toroidal transformers UL Approved to UL506. The facility holds ISO 9001:2015 (Quality Management System), ISO 14001:2015 (Environmental Management System) and ISO 45001:2018 (Occupational Health and Safety Management System). It has also been granted approval by a number of national and international companies in the electronics, aerospace and medical industries.
