For low frequency applications, e.g. motor control and linear power supplies, gapped silicon steel cores have proved to offer an effective solution at modest cost. Chokes for suppression of symmetrical disturbances. Chokes for power factor correction. We wind on iron powder and ferrite cores. Our speciality is chokes on air gapped silicon steel cores, which often combine a cost effective solution with excellent performance.
Most current transformers are wound on toroidal cores.
We manufacture a low cost range of current transformers for power control and power monitoring.
