Power supply protection device with filter SP-230F


SP-230F is intended for protection of the electronic equipment against radio interference in the range from 10 kHz to 30 MHz, as well as against induced voltages caused by high-energy electromagnetic pulses (lightning, electrostatic discharges, etc.) in 220V lines.

SP-230F is Class III single-phase protection device meeting the requirements of GOST R 51992-2002 (IEC 61643-1-98), GOST R 50030.1-2000, and GOST R 50571.19-2000 by specifications and performance. SPF-220/8 is used in networks with TN-S grounding system and shall be installed within 1 a(b) to 2 lightning protection zones (according to IEC 1312-1).

The alarm signal about a dysfunction of SP-230 is passed into the external signalling circuit.

It may be taken from contacts #8, 9(NC).

  • The degree of climate protection according to GOST 14254 is IP20.
  • The device is available in a plastic case with mounting on a 35mm DIN rail.
