Lovato SASD5VR is a DIN rail mounted C2-D1 surge protection device for 5 V DC RS485 data lines with 10 kA nominal discharge current, 2.5 kA impulse current and remote status contact.
£90.14
The Lovato SASD5VR is a compact surge protection device (SPD) for RS485 data lines, designed to protect sensitive communication and automation equipment against transient overvoltages travelling along signal wiring. As part of the Lovato SASD data-line surge protection range, it provides coordinated C2-D1 protection for industrial RS485 networks operating at 5 V DC.
The SASD5VR combines a 10 kA C2 nominal discharge current with a 2.5 kA D1 impulse current and a maximum discharge current of 20 kA. Its maximum continuous operating voltage is 6 V DC, while a bandwidth of 30 MHz supports the transmission requirements of compatible RS485 communication circuits.
Designed for professional automation and communication installations, the SASD5VR occupies only 0.5 DIN module and includes a remote changeover contact for status signalling. DIN rail mounting, replaceable cartridge construction and compliance with IEC/EN 61643-21 make it a practical solution for protecting industrial data networks against damaging surge events.
Industrial data lines can provide a path for transient overvoltages caused by lightning effects, switching operations and electromagnetic disturbances. The Lovato SASD5VR is installed in the RS485 signal path to limit these transient voltages and help prevent damaging surge energy from reaching sensitive communication interfaces and automation electronics.
Its C2-D1 protection capability, fast response and 30 MHz bandwidth make the SASD5VR suitable for coordinated protection of RS485 communication systems. The integrated remote contact also enables the protection status to be incorporated into monitoring or control systems, helping maintenance personnel identify when intervention may be required.
