Discover the wide range of applications for Weber MT voltage and frequency converters, which provide a reliable power supply for internal vibrators or vibrator motors. They can be used anywhere from traditional construction sites to precast concrete plants.

Advantages of the EFU series electric converters:

  • Maintenance-free: WEBER's electronic converters require no maintenance, as no moving wearing parts are installed.

  • Safe: The encapsulated electronics protect the operator from short circuits and earth faults as well as residual currents (RCD principle), while protecting the converter from overload and overheating.

  • Versatile and powerful: Depending on the type and number of sockets and the level of current output, it is possible to operate several vibrating needles or internal vibrators.

  • Lightweight and easy to transport: The EFU electric converters are easy to transport. A tubular frame protects the converter and serves as a carrying handle.

  • Integrated accessories: 3 m connection cable with plug are included in the scope of delivery, as is the motor protection switch against overload.

Special feature EFU Twin converter

Consumers with 48 volts and 250 volts can be connected to the EFU 2.7-Twin converter at the same time, which increases its versatility.

Important instructions for use

  1. The converter output voltage (volts) must always match the voltage of the vibrating needle (volts).
  2. The current consumption (amperes) of one or more vibrating needles must not be greater than the current output of the converter (amperes).
  3. The number of vibrating needles to be connected to a converter is limited by the number of sockets available.
