Circuit & System Protection


Protect your signal and datalines from surges and interference

10 September 2003 Circuit & System Protection Fire & Safety

Bourns Series 1600, 1700 and 1800 surge protectors are designed to shield sensitive equipment connected to data and signal interfaces from damage or upset caused by electrical surges. These signal and dataline protectors are all heavy-duty multistage.

In operation, a solid-state section will intercept the leading edge of the surge in sub-nanosecond response time. Within a few microseconds, a 3-pole balanced gas tube, capable of handling 20 000 A of lightning current, will crowbar the surge to ground. The protector remains in the crowbar state until the surge has passed and line voltages return to safe levels.

These protectors automatically restore the line to normal operation and await the next surge without the need to reset a breaker or replace the fuse. Protectors are generally placed as close as possible to the equipment to be protected. On daisy-chained applications, such as the RS485 or Fieldbus, a separate protector must be installed at each equipment node.

The Bourns 1965 Series coaxial surge protector is intended for use with low power VHF and UHF transmitters, 2-way base station transceivers, and receive-only systems. All models provide GDT technology. The 1965 arrester is symmetric and bidirectional, so either end may be used for the input or output. Various power, voltage and connector choices are available.

Typical applications include: RS232; RS422; RS485; Ethernet; closed circuit video; 4-20 mA; and HART and Fieldbus interfaces.
