9V 2A 18W switched-mode stabilized power supply, DC plug 2.1/5.5mm + 90 cm cable

9V 2A 18W switched-mode stabilized power supply

9V 2A switched-mode power supply is designed for maximum efficiency and safe operation. Thanks to a wide input voltage range from 100V to 240V AC, the unit automatically adapts to the mains voltage. It is a universal power source, well suited for Arduino and many other applications.

Standard polarity with positive in the centre and negative on the outer sleeve of the DC plug ensures compatibility with many devices requiring 9V DC power. Stabilized output voltage ensures connected equipment runs without interference. The power supply delivers a maximum current of 2A, corresponding to 18W power.

A cable approximately 90 cm long allows flexible routing, and the compact housing makes it easy to place the adapter in tight spaces. The tubular DC power plug 2.1mm / 5.5mm / 10mm is a standard solution that fits many electronic devices, providing a secure and stable connection.
