Consists of a modular line filter that can be fitted together to increase the number of sockets. Initially composed of a base unit with three sockets and one plug, one protection fuse, one on/off switch, one LED and a power cable. The socket located at the end of the bar is the main novelty of the system, since it can accommodate larger plugs (with transformers) that normally don’t fit well in conventional line filters, since they block the adjacent socket. A second module is composed of only three sockets and one plug. The innovation consists of being able to combine the modules, and the geometric shape allows for a perfect fit. The on/off switch is integrated into the body, with an LED to indicate the status.
