MAHES bushing machine power unit, parallel resonance and voltage intermediate circuit system is produced. They are manufactured as 75kVA, 100kVA and 125kVA as standard. At lower and higher power, special production is realized for customer demand. Isolated output transformer eliminates the danger of electric shock of the coil. The resonance frequency is monitored continuously, so that the max. yield is obtained. Advanced overcurrent protection circuit, high temperature control, cooling water pressure warning converts the induction heating machine into a safe structure.
