The switch-mode topology regulates voltage under load more efficiently than linear transformers, reducing heat output and mains consumption whilst maintaining stable voltage at the device end.\u003c\/p\u003e\n\u003cp\u003eDesigned for powering routers, CCTV cameras, small radios, handheld gaming consoles, portable speakers and similar low-draw devices, the PSU accepts 100-240V AC mains input at 50\/60Hz, making it compatible with UK, European and worldwide mains voltages when used with the appropriate plug adaptor. The output current holds at 600mA across all seven voltage settings (3V, 4.5V, 5V, 6V, 7.5V, 9V, 12V), selected by a rotary switch on the body. The included DC barrel plugs span 3.5mm jack, 2.35 x 0.75mm, 3.5 x 1.35mm, 4 x 1.7mm, 5 x 2.1mm, 5.5 x 2.1mm, 5.5 x 2.5mm, and 6.3 x 3mm outer\/inner diameters.\u003c\/p\u003e\n\u003cp\u003eThe compact 41 x 64 x 51mm body weighs 120g and fits behind furniture, inside AV racks, or in travel bags without adding bulk. The UK three-pin plug is non-folding but protrudes only minimally from a wall socket. Switch-mode efficiency reduces standby draw and running temperature compared to older linear power supplies, which matters when the PSU is left plugged in continuously to power always-on devices like security cameras or network equipment.\u003c\/p\u003e\n\u003ch5\u003eSpecification\u003c\/h5\u003e\n\u003ctable class=\"spec_table\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower max.\u003c\/td\u003e\n\u003ctd\u003e7.2W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAdaptor plugs\u003c\/td\u003e\n\u003ctd\u003e3.5mm jack, 2.35 x 0.75mm, 3.5 x 1.35mm, 4 x 1.7mm, 5 x 2.1mm, 5.5 x 2.1mm, 5.5 x 2.5mm, 6.3 x 3mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput voltage\u003c\/td\u003e\n\u003ctd\u003e100-240Vac, 50\/60Hz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutput current max.\u003c\/td\u003e\n\u003ctd\u003e600mA (all output voltages)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutput voltage\u003c\/td\u003e\n\u003ctd\u003e3\/4.5\/5\/6\/7.5\/9\/12Vdc\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e41 x 64 x 51mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e120g\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch5\u003eDownloads\u003c\/h5\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0729\/8993\/3835\/files\/661400UK.pdf\" target=\"_blank\"\u003eProduct Manual\u003c\/a\u003e\u003c\/p\u003e\n\u003ch5\u003eFrequently Asked\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eWhat devices can this power supply run?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe PSU suits low-power devices drawing up to 600mA at any of the seven voltage settings. Common uses include routers, CCTV cameras, portable radios, handheld gaming consoles, and small speakers. Check your device's power rating before connecting — if it requires more than 600mA or operates outside the 3-12V range, this PSU is not suitable.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow do I select the correct voltage?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eA rotary switch on the body lets you select between 3V, 4.5V, 5V, 6V, 7.5V, 9V, and 12V. Set the switch to match your device's required input voltage before plugging in.
