November, 2008:

SolaHD is pleased to introduce a new line of unshielded general purpose distribution transformers that provide a cost effective solution ideal for many applications.

The unshielded transformers feature the same high quality and reliability that have made SolaHD’s ET series of low voltage general purpose transformers successful. The new models have the same part number only with the “S” suffix removed (ex. ET2H75S for the shielded version, and ET2H75 for the unshielded version). The initial offering includes the eight most popular part numbers (ET2 and ET5 Series, 15 kVA through 75 kVA).

The new unshielded transformers are compatible with the current shielded units in most applications.
