ERDHUNG-2K Electric Noise Filter

Share this

The Erdhung-2k electrical noise filter is a unit designed to perform electrical noise filtering and deliver electrically neutral ground references, according to the conditions required by modern electronic circuits.

Also suitable for modern communication systems, current data systems and automation processes.

Conditions Required by Current Electronic Circuits


Unique reference to the Electrically Neutral Ground

In order to avoid the negative results of overvoltages generated by lightning or electrical surge peaks caused by the practice of maneuvers, as well as to avoid variations in the programs of the electronic circuits that are caused by parasitic currents.


Reference as close as possible to 0 Ω (ohm)

with respect to the electrically neutral ground.

The Most sensitive electronic equipment requires a maximum of 1. The ERDHUNG 2k® electrical noise filter ensures values very close to zero.


Noise free references for electronic circuits

References for communication circuits must be noise-free up to 30 KHz and those for computer circuits up to 50 MHz.

The ERDHUNG 2k® electrical noise filter ensures both specifications in its "B.E.P. FILTERED" output.

Equipotential Bonding Bars 

The Erdhung-2k electrical noise filter has 3 equipotential bonding bars whose applications are described below:

General Grounding:

This equipotential bonding bar is intended to concentrate the contribution of all the structures that can collaborate to produce a very low connection to the electrically neutral ground. 

Among them the two most common are: metallic structure of buildings, water pipes, gas and all kind of fluid distributed inside the building by metallic pipes.

Electric Grounding:

It is intended for the connection of all electrical grounds that do not need to be filtered.

Electronic Grounding:

Designed to connect all electronic systems that are sensitive to "electrical noise" of the line power supply, and is intended to deliver a filtered ground up to 50 MHz.

AC Filter (Optional)

The unit is combined with a single-phase AC serial filter, capable of shunting to ground up to (6) KA max and supporting a maximum load of 10A.
