Transformer input voltage
Yes. If the input voltage matches your line - neutral or line - line voltage it will be fine.

Just be careful that if you require isolation that it is an isolating transformer with no connection between the primary and secondary. Some transformers are auto-transformers with shared primary and secondary windings. These do not provide isolation.
