The need of surge protections is growing rapidly. Newest gene-ration of sophisticated electronic devices are more sensitive to electrostatic discharges and over-voltage spikes in power distribution networks requiring new approach to the design of protection devices with improved quality and reliability. The approach of integrated multistage surge protection system AC DC MOS Protector significantly reduces the total cost trough:

1. Applying standard IEC 62305 & ANSI/IEEE C62.41.1-2 (Lightning international protection standard) requires several independent surge protectors installed separately in each boundary protection zone LPZ0a/LPZ0b-LPZ3 & C-A. AC DC MOS Protector presents multistage protection system with 8 (eight) protection stages in one device, expelling the need of using surge protectors in other protection zones, while reducing surge current up to 99.9% (at single point) in LPZ0a/LPZ0b-LPZ3 boundary zones;
2. Expel installation and cost of several independent surge protectors according to lightning protection of boundary zones;
3. Expel the need of surge expert engineer regarding installation of several protectors in different places;
4. Expel need for coordinated protection;
5. Reduce the cost of protector installation;
6. Reduce space requirements;
7. Lower maintenance expenditures;
8. Extremely high protection efficiency and reliability;
9. Reduced cost of maintenance of the protected equipment regarding higher MTBF;
10. AC DC MOS Protectors are excellent choice for investment in quality of your power network supply. If the stages 2,4 and 6 are out of function, the stages 1,3 and 7 are still provide a high grade cascade bi-directional filtering among with ultimate (5-th) protections stage;
11. Recommended usages of integrated multistage surge protection system AC DC MOS Protectors on sites were standard IEC 62305 & ANSI/IEEE C62.41.1-2 (Lightning international protection standard) was not implemented on boundary zones LPZ0a/LPZ0b-LPZ3 & C-A or in case of absence of any other surge protectors;
