TBUS power sockets are available in single and dual, country?specific modules. Modules are available with AC power sockets and/or USB charging sockets. Note: The Universal power socket is fully compatible with power plugs in the UK, India, Italy and Denmark, as well as with the 2–prong Europlug. It is partially compatible (if the polarity is reversed) with plugs in China, Switzerland, Israel and the USA. The universal power socket does not supply grounding to plugs in Central Europe and France (you should order country specific sockets instead). It is not compatible with South African plugs.
