Bernard Bonnefond S.A.S. products

I.V.R. is an On-load, Stepless Voltage Variation and Current Regulating Equipment, Its Design is close to an Asynchronous Motor with a Wound Rotor. I.V.R. works like a Rotating Field Transformer, Power Range: from 30 kVA to 3 MVA.

  We can propose variable power supply by Thyristor, composed of a transformer with fixed contact and with cubicle Thyristor, in particular to feed the FEEDERS in the glass factory, from 10 to 300 kVA.
