PLC Electric Filter

Reduction of electrical noise in homes with the PANDA15X2 power filter

In residential and office environments, many electronic devices generate high-frequency disturbances that superimpose on the 50/60 Hz mains signal. This phenomenon, known as dirty electricity, can increase the level of conducted interference on the wiring and, in some cases, worsen discomfort in sensitive people or in spaces associated with the sick building syndrome. The electric filter is presented as a technical mitigation solution: a parallel filter that plugs directly into a socket to reduce part of that high-frequency content at the point of use.

Unlike solutions that require intervention in the distribution board, this filter installs in seconds and allows zonal action, prioritizing the highest-emitting equipment. The recommended strategy is simple: locate the source (for example, AC/DC adapters, chargers, compact lighting or power electronics) and place the filter in the nearest socket to increase the local effectiveness of the filtering.

Applications of the PLC filter for dirty electricity

• Homes: reduction of conducted disturbances in circuits with a high density of consumer electronics.
• Offices: support in environments with switched-mode power supplies, displays, printers and power strips with multiple chargers.
• Point-by-point installations: treatment of multiple sources using several units in different outlets, without works or changes in the distribution board.

Key features for dirty electricity control and safe use

• Plug-in parallel filter, designed to operate close to the source of contamination.
• Design intended for indoor use, meeting electrical safety criteria and certification.
• Pass-through: allows continued use of the outlet where it is installed, avoiding the loss of a connection point.
• Internal protections and discharge elements for controlled behaviour during operation.

Installation and usage recommendations (socket-mounted power filter)

• Connect the filter to a power outlet as close as possible to the device generating the electrical noise.
• If there are several relevant sources, use multiple units distributed throughout the installation.
• No electrician is required for its use on a socket; avoid overloaded power strips and follow good electrical safety practices.
