Frequency

The rated frequency is the frequency for which the transformer is designed.
For inquiries and orders without frequency information, we assume a frequency of 50-60Hz and a sinusoidal input voltage.

Note 1:
A transformer cannot transform frequency. The frequency of the output voltage is identical to the frequency of the input voltage.

Note 2:
Transformers explicitly ordered for a frequency greater than 50Hz lead to smaller core types than 50Hz transformers of comparable performance. However, they cannot be operated – not even for testing purposes – with 50Hz and rated input voltage.

Note 3:
A transformer labeled with a rated frequency of 50Hz can be operated with 60Hz without any concerns.
