DESCRIPTION
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.
