AC/DC Power Supplies (5V & 12V)

These wall-mount adapters convert standard AC outlet power to stable DC for electronics projects, like powering Arduino boards (5V) or motors/relays (12V). They're reliable for first-year engineering students testing circuits without batteries.

5V Power Supply

Model: LJH-520

Input: Universal 100–240V AC (works worldwide with plug adapter)

Output: 5V DC at 2A (10W)—ideal for USB devices, LEDs, or microcontrollers

Connector: Typically 5.5mm barrel jack (check polarity: center positive)

12V Power Supply

• Model: LJH-1220
• Input: Universal 100–240V AC
• Output: 12V DC at 2A (24W)—suits small motors, strips, or relay modules
• Connector: Typically 5.5mm barrel jack (center positive)

Tip: Use a multimeter to verify voltage before connecting sensitive gear.
