Current Transformers

Standex Electronics has a long history of developing current transformers to solve unique customer challenges. Current transformers (C.T.) are used in power supplies to accurately sense and measure current flow. Their primary function is to prevent overcurrent conditions as well as monitor and control power supply circuits.

Additionally, our custom engineered transformers are designed for extreme conditions and hazards. Such as high temperature, radiation, humidity and other extreme environmental needs.

“Standex Electronics provides global support for a wide range of current sensing applications.”

Typical Current Sense Applications

  • Over-current sensing for circuit breakers
  • Isolated current sensing for appliances
  • Load variation sensing for frozen drink machines
  • Current sense transformers for load house monitoring
 
  • Over-current sensing for home appliances
  • Transformers to power refrigeration units for refrigerated trailers
  • Automatic transfer switches
  • Current monitoring for power factor

Current Sense Transformers for Power Supply Circuits

Solving Your Complex Needs

Customers rely on Standex for custom designs that address individual requirements and application needs. First, Standex Electronics engineers begin each project by understanding the end-result desired. Second, we determine an appropriate means to achieve it. Third, we offer ideas and engineering expertise at each step of design process. Finally, we deliver a solution that is on target and budget. This is the Standex partner, solve, deliver® approach.

Custom C.T. Mechanical & Electrical Options

Current sense transformers can be designed in an open toroidal construction, SMT or be custom molded. Moreover, virtually any desired current ratio, output or capacitance can be met. Also, many termination options are available – including P.C. mount, flying lead, custom leads, hermetic connectors, and more.
