Transformer FAQ - Can 60Hz transformers run at 50Hz ?
Transformer is a device that uses the principle of electromagnetic induction to change the AC voltage. The main components are primary coil, secondary coil and iron core.
Peaco Support transformers operate at 50Hz/60Hz. The output frequency will be the same as the input frequency. From the technology point of view, a transformer can't change the frequency. Phase converter can change the frequency.
