Blue Prints Of Noahs Ark Protection for data control systems

is applications. The main industrial buses can be divided into four levels (control, field device and sensor) and at least three of them have similar physical level and are protected by SMH-TC units.

SMH-TC series has powerful gas discharge tubes (GDT) of three poles to divert the energy of the primary surge. The next phase of protection is carried out using diodes "avalanche" of silicon bidirectional to ensure minimal insertion loss and extend the operational frequency range 30 MHz SPD

These devices benefit from the use of two protection circuits in same package to meet the requirements of applications with space constraints. Pa
