Encapsulated IP 23, PUK 23 3,0-31,5kVA

These transformers are designed for temperature class F or H to minimise the weight. The transformer’s protective structure is made of H-class insulation materials with built-in air channels, enabling highly effective cooling when the device is equipped with forced-air cooling.

It is technically the same as the PU type, but it is encased in an IP23-standard steel casing—standard colour RAL 7035.

This structure can also be used for chokes for various purposes.
