YEG Powerline has 25 years of power supply design expertise and our knowledge of power supply product development and manufacturing enables us to be a specialist resource to our customers. The design process can start from very basic information or ideas and from that we can produce your initial product specification and mechanical drawings as part of a detailed proposal.

Our custom products include:


  • AC/DC power supplies
  • Rectifiers and battery chargers
  • DC/DC converters
  • Sine-wave inverters
  • Phase and frequency converters
  • DC-input dimmable back-light inverters for LCD displays
  • DC-output UPS systems
  • Laboratory power supplies
  • Complete power systems in 19" and 23" racks.

The designs are optimised for the user application, e.g. low electrical noise, unusual load demands or harsh environments and will incorporate only the features required by the customer thus minimising unit cost.  Custom power supplies are designed and built with required cabling and mounting points ready for turnkey installation.

Time scales to produce engineering prototypes varies depending on complexity but is typically 8 weeks but this can be less if we are modifying an existing product.

We have experience of custom design in the following applications: 

  • Access Control
  • Broadcast
  • Custom 19" & 23” Rack Systems
  • EPOS
  • Fire Detection
  • Industrial
  • ED Displays and signage
  • Medical
  • Professional Audio
  • Process Control
  • Railway
  • Scientific Instruments
  • Traffic controls
  • Weighing

We can design and manufacture power supplies in almost any voltage and current and multiple output combinations with the required control.

The power supply styles can be open frame right through to enclosed product with IP5x or IP6x protection plus additional ruggedisation.

Proving compliance to all required standards may involve using external test facilities; however our designs are tested using pertinent in house tests from the following:

  • Conducted EMC
  • Radiated EMC
  • Harmonics
  • Mains born high energy surge testing
  • Voltage Dip and Surge testing
  • Climatic chamber
  • High resolution thermal photographic imaging
  • ESD up to 15 KV
  • Fully automated power supply test equipment
  • Transient response and bode plot analysis (optimises power supply response)
  • Isolation (including type testing)
  • Safety critical magnetic component isolation with-stand.

The production facility has over 20,000sq ft of production area. The entire design and manufacturing process is controlled by stringent quality procedures in accordance with certification to BSEN ISO9001:2000
