• Common mode interference can also be a problem and most microprocessor-based equipment will require a supply with this earth to neutral noise factor limited to less than 0.25V peak. For this reason you may be considering installing a "clean line" from the mains distribution point, but this will not always give the required level of protection. Line conditioning is the more positive solution, achieved by fitting an isolation transformer with the secondary neutral linked to earth. This isolation transformer eliminates the need for a dedicated line and at the point of linking neutral to earth the common mode interference is ZERO. Stabilisers with added interference suppression are often referred to as "Line Voltage Conditioners" or "Power Conditioners".

The POWER SHEILDare essentially designed to attenuate Surges as defined in IEC 1000-4-5 to safe levels. The surge energy is absorbed in the circuit and dissipated and it is not diverted to ground bus etc.

The POWER SHEILD  are essentially designed to attenuate Electrical Fast Transients as defined in IEC 1000-4-4 to safe levels. The Transient energy is absorbed in the circuit and dissipated and it is not diverted to ground bus etc.The filters are ideally suited for applications in industrial environment where many electronic fast switching devices operate at 2kHz switching frequencies and source/load impedances vary from one location to another and from one machine to another
