CLASSIC SKSE – 800kVA to 1700kVA

Extending the SEMISTACK CLASSICS range, the CLASSIC SKSE is a modular product specially optimised for rectifiers, but other configurations can be realised as well. Using the well established capsule technology, the new Z5 heatsink profile, simplify stack construction and provide modularity. Able to accommodate high performance axial fans, customisation is possible to achieve fan redundancy, or other fan supply voltages. The CLASSIC SKSE range, dedicated to low voltage applications (500Vac), is by design, easily scalable to a higher voltage range.
