Three Phase Power Controllers

Three Phase Power Controllers The EFS is a series of power controllers for controlling heating cables and electrical radiators.

The EFS is engineered using the latest technology, which provides several benefits such as accurate, noiseless control as well as long life expectancy. The EFS has often proved its value in applications where control of major electrical heating outputs has been required.

The EFS is not only ensuring the precise control of heating surfaces in ventilation and industrial plants but also in ceilings, floors and radiant heating etc. The EFS series has been developed to give our costumers an advantageous combination of high quality, accurate control at any heat requirement and low life cycle costs.

Type EFS

Available in limited quantity.

EFS is a series of power controllers designed to control temperature via electric heating elements, e.g. in ventilation systems, electric radiators, electric underfloor and ceiling heating systems or radiant heaters. EFS is particularly suitable for infinitely variable control of large power outputs, e.g. in ventilation systems where supply air temperature is accurately controlled using electric heating elements.  EFS need simply be connected to an electric heating element and a temperature sensor to create a complete heating system.

EFS power controllers are sturdily designed to provide our customers with an advantageous combination of high quality, precise control and low lifecycle costs.

  • Remote temperature setting
  • Built-in power doubling relay
  • Can be used together with an external controller
  • Infinitely variable control of large power outputs
  • Sturdy design






  • What is the difference between EFS-9252 and EFS-9253?


    2 or 3 phased Power controller

    The difference between EFS-9252 and 9253 is the number of thyrister in the unit. 9253 has 3 thyristers - and the 9252 only 2. 9253 is only used if the heat source is star connected and star point is connected to neutral.
