Frequently asked questions
Can I use it to power a 24V AC device?
No. The output is 18V AC, so a 24V AC device will be underpowered and may malfunction. Check the required AC voltage of your device before connecting it.
Is it safe to wire the input directly to mains?
Mains wiring should be done by a qualified person with the supply disconnected. Insulate all mains connections and mount the transformer inside an enclosure.
