Oxford Electrical Products was established in 1982 and quickly became one of the UK's leading and most highly respected wound component manufacturers. OEP has always been renowmed for its audio, pulse, line isolating and mains transformer ranges but over the years the ranges and product offerings, along with the customer base, has expanded rapidly to embrace switch-mode, toroidal, SMDs, flyback, digital transformers and many other standard or customer specific products. In January 2006, OEP became Walters-OEP as a member of The Walters Group, a highly regarded UK organisation established in 1970.
