Step Down voltage converters are for using equipment from the USA in the UK or Ireland. They have a 3 pin UK power plug and a US socket
A simple plug-in step up transformer which allows US electrical mains operated equipment to function in the UK mains system which is 230-240110-120V. The transformer has an internal safety cut out device to protect against overload. The moulded plastic enclosure produces an attractive product, featuring double locking of the enclosure to prevent damage following mis-use. Full encapsulation of the transformer improves heat dissipation and prevents ingress of moisture. Toroidal construction allows lower height, negligible external magnetic field, improves efficiency, smaller size and reduced weight.
