Surge-Trap® Signal - STS 485

STS 485 is the series of surge protection devices for equipment connected to RS485 networks. The ranges offer a number of formats, voltages and numbers of protected lines and are designed especially for a variety of applications. These are protectors for a final step of very fine protection to be installed as close as possible to particularly sensitive equipment connected to these communications lines. Meets the IEC 61643-21 standard.
