The DS210..DC surge protector is designed to protect equipment connected to DC (and AC) power supplies from lightning surges. It is based on varistors matched to the network voltage (12, 24, 48, 75, 95,110 and 130Vdc): the varistors have thermal disconnection devices to control any end-of-life case. A green LED that indicates «Power On» when lit and «Disconnection» when off, facilitates maintenance. In addition, the «surge protection» function is pluggable to make replacement simple and rapid (spare module: DSM210-..DC).

The DS210..DC is DIN rail compatible and is connected in parallel on the line to be protected.
