You need a compact 12V supply for a controller board, a small motor, or a DIY project and the last one you bought either hummed like a fridge or tripped the breaker on startup.
This JAYCAR IRM-45-12ST is a miniature AC-DC module. 45W output at 12VDC, 3.8A. Takes full-range 85–264VAC input, so it doesn't care whether you're on a 240V domestic circuit or a 220V industrial feed.
Short-circuit, overload, and over-voltage protection are all built in. No-load draw is under 0.1W, so it's not quietly sipping power when the thing it feeds is off. Flame-retardant case. Rated from -30°C to 70°C. Three-year warranty.
Drop it into your enclosure, wire the input, and stop worrying about a $12 supply taking out a $400 board.
