Description
Regulated 7.2 W DC Supply
The 9V 0.8A power adapter provides 7.2 W of regulated DC output from a universal AC input. It suits Arduino boards, small routers, audio gadgets and bench test fixtures. The fixed barrel plug measures 5.5 mm outside and 2.1 mm inside.
Input range covers 100–240 V AC at 50/60 Hz, so the supply works on UK, EU and US mains without a selector. A switching regulator holds 9 V DC under load and limits ripple to roughly 120 mV peak-to-peak. Output current caps at 0.8 A.
Centre-positive polarity matches most consumer electronics and development boards. Verify the device socket before connecting. The moulded case measures 70 × 42 × 28 mm and the lead runs 1.2 m. Operating temperature spans 0 °C to 40 °C with convection cooling only.
Key Features
Universal AC Input
The supply accepts 100–240 V AC at 50/60 Hz from any regional wall outlet.7.2 W Regulated Output
The converter holds 9 V DC at up to 0.8 A across the rated load range.5.5 x 2.1 mm Barrel Plug
- Fits the common DC jack on Arduino shields and small routers
- Centre-positive polarity with outer negative return
- Moulded strain relief at the plug junction
Switching Regulator Topology
A high-frequency switcher keeps efficiency high and heat output low at full load.Low Ripple Output
Ripple stays near 120 mV peak-to-peak, which suits sensitive audio and radio equipment.Built-In Protection
Over-voltage, over-current and short-circuit circuits shut the output down before damage occurs.Compact Moulded Housing
The 70 × 42 × 28 mm case fits behind desks and inside equipment cabinets.

Why Choose This DC Supply
Universal mains input removes the need to stock separate regional variants.
The 7.2 W rating leaves headroom for devices that draw under 0.8 A continuously.
Over-current and short-circuit protection reduce risk during bench testing and field swaps.
Fanless convection cooling keeps the unit silent in offices and bedrooms.
Level VI efficiency and low no-load draw cut standby power in always-on installations.
