Transformer Specifications

This datasheet provides specifications for air conditioning, refrigeration, and appliance transformers.

Groups and Characteristics

The transformers are categorized into three groups: GROUP B, GROUP €, and GROUP D.

GROUP B transformers have primary voltage taps of 230-260, 210-239, and 189-217, with nominal secondary voltage of 115.

GROUP € transformers have primary voltage of 200/220/240, with nominal secondary voltage of 115, and frequencies of 50/60 Hz.

GROUP D transformers have primary voltage of 230, with nominal secondary voltage of 115, and frequencies of 50/60 Hz.

Each group has various models with different VA ratings, output amps, and physical dimensions.

The datasheet also notes the importance of not exceeding +5% of nominal voltage without changing taps.
