CM Converters - Frequency and Voltage Converters

Frequency and Voltage Converters consist of an electric motor coupled to a permanent magnet generator that reduces the single-phase (230 V, 1 ph) or three-phase (400 V, 3 ph) input voltage into one lower than 50 V increasing the frequency to 200 Hz, necessary for correct operation of electric internal vibrators, thus ensuring operator safety as occurs with low voltage equipment.
Converters are suitable for continuous duty.

With multi-socket models a maximum of four multiple high frequency concrete vibrators can be connected simultaneously, as long as total power consumption does not exceed the rated current of the converter. To facilitate the maneuverability, depending on the model, a handle or a grip frame with coupling or wheels is provided.
  • Available in 230 V, 50 Hz, single phase (two models) or 400 V, 50 Hz, three phases (four models)
  • 1 ~ 4 outputs for connecting high frequency poker vibrators
  • Output power: 1 ~ 6.2 kVA
  • Insulation class F
  • IP 44 protection
  • Overload protection
  • Ambient temperature: -20 ~ 40 °C (-4 ~ 104 °F)
  • Smooth, robust aluminium casing
  • Forced ventilation
