65kVA Power Unit

Stork’s transformer units (Mannings model) have achieved a worldwide reputation for cost effective design, quality and reliability having been successfully operated on heat treatment projects in some of the most demanding climates and industrial environments around the world, for over 50 years.

The 65kVA unit consists of a robust, natural air cooled, 3 phase transformer which is built into a compactly designed, strong, steel case which together provide the unit with a long working life expectancy. Each output channel is controlled by means of an internal energy regulator working in parallel with a digital temperature controller. Provision is also made for connection to external control from any compatible programmer/control unit. Switching between internal (manual) control or external (automatic) control mode is made via each channel’s auto/manual selector switch.
