Description
The 220 volt mains power supply is often contaminated by noise carried over the actual power cables itself.
This noise can be reduced significantly by using a common-mode noise rejection device in the power lead to your equipment.
This is the exact same 15 Amp CMR (common mode rejection) toroid that we use in case you want to build your own device.
