Supra MD01-16-EU DC Blocker

DC blocker

DC voltage derives from a number of modern electrical appliances and will cause an offset on to the alternating mains power sine waves. This offset is the result of an electric asymmetry that do not equally load the AC positive and negative sine wave. In the ideal mains power supply there should be no DC-offset at all.

 

This DC offset limits the power supply efficiency in most multimedia and hifi equipment and causes transformers to saturate (iron core saturation) already at low level of DC voltage. The transformer DC resistance is close to zero, why the current will be quite substantial even though a DC voltage at between 0.5 and 2 Volt does not seem alarming in any way. It increases iron core and conductor winding heat build-up and may even cause transformers to sound (vibrate) with a humming noise.

 

Eliminating DC off-set may thus prolong life of the equipment by means of preventing excessive heat and remove physical wear of the winding insulating enamel. The sonic impact is in most cases quite dramatic and again it will scale off audible sounds not belonging to the recording. You will hence listen and/or watch the actual recording instead of any mains power irregularities.

 

Mains cable is not included with this product. It requires a cable with a 16 amp connector, like Supra's 16 amp mains cable
