Surge suppression filters SF25M

The SF16M network interference filter (hereinafter referred to as the filter) is used to protect the power supply circuits of electronic devices from industrial and high-frequency natural interference, as well as to prevent the spread of industrial interference through the supply network circuits from industrial equipment.
The filter is switched on when the power supply line breaks. For connection to the supply network and the load, the filter has two groups of screw terminals.
The filter is available in a steel housing that does not support gorenje, and provides for the device to be bolted d = 7 mm. 
In accordance with GOST, the nature of the interference is divided into antiphase and common-mode. The current of the antiphase interference in the signal wires coincides in the direction with the current of the useful signal. The common-mode interference current has the same direction in the forward and reverse wires of the network.
The filter is designed to effectively suppress various types of interference, thus providing protection against:
- Lightning strikes near cables or power lines;
–
