In rare cases, operating electrical devices can introduce high interference pulses into the 230 V network, which may disrupt digitalSTROM communication. This can occur, for example, when multiple switch-mode power supplies are operated in close proximity to each other. The device filter is installed in such cases before the interfering device and minimizes the impact on the network from high-frequency disturbances. The dS-FD210 is designed for high-power devices up to 16 A, such as solar systems and induction cooktops. For plug-in devices up to 4 A, please use the dS-FD200.
