Supra LoRad DC-Blocker - Removes up to 3.6 VDC from the mains power AC
Now, Supra Cables has taken yet another step to minimize the impact from malicious elements like DC (Direct Current) superimposed on the mains AC (Alternating Current) in most modern households and industries!
DC voltage derives from a number of electrical appliances and will cause an offset on to you alternating mains power. This offset is the result of electrical devices that do not equally load the AC positive and negative phase. In the ideal mains power supply there should be no DC-offset at all
