Frequently asked questions
Can I connect it directly to mains?
The primary side is designed for 220 V AC mains. Mains wiring is dangerous: use an enclosure, insulated connections and a fuse on the mains side, and have a qualified person handle the wiring.
How much load can it supply?
The rating is 3 A at 24 V AC, which is about 72 VA. Keep the total connected load below this. Inductive loads such as contactors can draw a higher inrush current than their running current.
