SPD RS485 (version 1)

RS485 series surge protection devices (SPDs) are manufactured while using multi-stage protection circuits. They are used to protect communication circuits, working with RS-485 protocol. A gas-filled surge arrester is used as a rough protection in the circuits and as the fine protection element - a transient voltage suppressor (TVS), as well as in some transient blocking unit (TBU) versions from Bourns company.
Such a solution contributes to high diverting ability achievement, a sufficiently low threshold for the protection (the operating voltage of the SPD) and a high response speed. SPD data are connected in RS-485 interface circuit. There is a chance to connect both shielded and non-shielded RS485 interface lines. -
