The FSP-1F-20A filter is designed to protect electronic devices and computing equipment from information leakage via grounding circuits and power supply circuits with a voltage of 220V 50 Hz or direct current up to 220V, as well as protecting them from pulse and high-frequency interference. It is made with 3 wires. The filtered working current is up to 20A. It protects against voltage surges in the network. It is made according to the UHL 4.2 category of GOST 15150-69 for installation in consumer products or systems. It ensures protection of power supply networks of premises of the 1st category. The lengths of L1 and L2 can be changed at the customer's request.
