ESP RS485, RS485Q & SL RS485 Series LPZ0 RS485 A 3 RS485Q 0A 3 SL RS485 0B 3 NEW Installation Connect in series with the signal line either near where it enters or leaves the building or close to the equipment being protected ensuring it is very close to the system's earth star point. Install protectors either within an existing cabinet/cubicle or in a separate enclosure. CLEAN ESP RS485 ESP RS485 DIRTY From line Earth To equipment ESP RS485 installed in series LINE Max surge current Let-through voltage, Up To equipment Earth Features and benefits Very low let-through voltage (enhanced protection to BS EN 62305) between all lines - Full Mode protection Full mode design capable of handling partial lightning currents as well as allowing continual operation of protected equipment Repeated protection in lightning intense environments 45 MHz bandwidth greatly exceeds 12 Mbps maximum speeds Low in-line resistance minimises reductions in signal strength Suitable for earthed or isolated screen systems Built-in DIN rail foot for simple mounting to top hat DIN rails Convenient earthing through DIN foot and/or earth terminal ESP RS485 can be flat mounted on base or side ESP RS485 and ESP RS485Q have colour coded terminals for quick and easy installation check ESP SL RS485 has ultra slim 7 mm width ideal for compact protection of large numbers of lines (e.g. process control installations) ESP SL RS485 includes two stage removable protection module with simple quick release mechanism allowing partial removal for easy line commissioning and maintenance as well as full removal for protection replacement ESP SL RS485 includes optional LED status indication - add L suffix to part number - i.e. ESP SL RS485L 3 S 4 20kA 63V Furse Wilford Road, Nottingham, NG2 1EB, UK Clean 1 S 2 From line CLEAN Lightning Barrier Nominal voltage 30V Max working voltage, Uc 36.7V Current rating 750mA In-line resistance 1.0 1.0 Line Combined Category D, C, B tested protector (to BS EN 61643) specifically designed for RS 485 and Fieldbus applications, such as Profibus DP. For use at boundaries up to LPZ 0A (ESP RS485 & ESP RS485Q), or LPZ 0B (ESP SL RS485) protect against flashover (typically the service entrance location) through to LPZ 3. Available as standard ESP RS485 format, or compact ESP RS485Q and Slim Line ESP SL RS485 versions for installations where a high number of lines require protection.
