About this product
Step-down transformer that converts 220 VAC mains to an 18 VAC secondary rated at 2 A, with two wire leads. It supplies low-voltage AC circuits, and it can serve as the input stage of a linear DC supply after rectification and filtering.

Frequently asked questions
Does it give a DC output?
No. The output is AC. For DC, add a bridge rectifier, a filter capacitor and, if needed, a regulator.
Can I draw the full 2 A at 18 V?
The rating corresponds to about 36 VA. Keep the load within 2 A, and make sure the mains side is fused and fully enclosed and insulated.
