Frequently asked questions
Can I mount it without an enclosure?
No. The input is mains voltage, so the module must be installed inside an insulated enclosure, and mains wiring should be done by a qualified person with the supply disconnected.
Can it power an Arduino board?
Yes, connect the 12 V output to the board's Vin pin or DC jack, observing polarity. Keep the total load within 410 mA, because the module's output current is limited.
