The POSC12100A is a reliable, regulated 12W power source designed to keep your prototypes running cool and safe. With a slim 28mm profile, it won't hog space on your power strip, and the 1.5m lead gives you plenty of slack to reach your workbench.

Why it’s in your Parts Bin:

• Clean Power Rail: With low ripple and noise (200mV+- max), it provides the steady voltage needed for sensitive logic circuits and sensors.

• Safety for Prototypes: Built-in hiccup mode for short-circuits. If you accidentally bridge a rail while probing your board, the adapter shuts down and "pings" until the short is gone—protecting both the adapter and your project.

• Efficiency Leader: Level VI efficiency rating means it doesn't waste energy as heat. It stays cool even when pushed to its 1A limit.

• Standard Connector: Comes pre-terminated with the universal 5.5/2.1mm DC jack (Center Positive), the gold standard for Arduino barrels and DIY power hubs.

Engineering Notes for Makers

• The Lead: The 1.5-meter 22AWG cable is sturdy enough for most 1A draws without significant voltage drop, but keep it in mind if you're extending the line for high-torque motor applications.

• Polarity Check: This is a Center Positive unit. Always double-check your PCB footprint or barrel jack wiring before plugging in.

• Mounting: At only 67g, this is light enough to stay put in vertical sockets, making it ideal for permanent wall-mounted IoT enclosures.

Mechaxil Bench Tip: If you're using this with a breadboard, pair it with a DC Barrel Jack Adapter (Screw Terminal) to easily break out the 12V and Ground rails without cutting the factory cable.
