Worlds first audio/video grade differential switch
Nowadays, audio grade fuse holders are quite common in the meter cupboard, however, the bottleneck still exists, namely your "standard" differential switch. Doepke introduces a version specifically designed for the most demanding audio/video enthusiasts who only settle for the very best. This differential switch has been designed by an employee of Doepke, who is a passionate audiophile too. In his spare time, he's worked for many years on this product, until it fully met his own standards: the highest possible audio- and video quality. In addition, this differential switch offers enhanced safety: even with deviating wave forms (as often introduced by switch mode power supplies) it switches off reliably. Differential switches are obligatory in all home electricity systems. The main goal is to protect against electrocution. A differential switch compares the in- and outgoing currents through live and neutral, the sum of these has to be zero. The only disturbance possible of this balance is, when a certain current flows to earth. If this currebt flows through the body of a human being, this can be life threatening. This is where the differential switch kicks in and disconnects the circuit from the mains if this current is over 30 mA. Audio/video enthusiasts sometimes tend to bypass their differential switch, this is however illegal and highly unsafe. Insurance companies will not pay if they notice this has been done. We strongly discourage doing so. The best thing is, you don't need to anymore with the introduction of the Doepke DFS differential switch.
