Surged Arrester with Enhanced Voltage Protection is used for EMC protection of electronic components with DC power supply. The Arrester is optimally suited and since a uni-polar diode is used, the polarity of the operating voltage must be observed. The Arrester can work under 24V power supply which is very low level operating voltage and for installation in conformity with the lightning protection zones concept at the boundaries from 1 – 2 and higher. Surged Arrester with Enhanced Voltage Protection is specifically designed for protecting power supply where voltage protection levels are adapted to the dielectric strength of the input circuit.
