Lightning Protector RS485

Description Function: – lightning protector RS485 is applied for protecting the sensitive signal equipments such as communication – special lines, telesignalisations, telecontrol signals, etc. It is widely used for protecting data transmission in computer communication system, monitoring control system, entrance guard interphone system, PLC automatic control system, and fire prevention alarm system. It can avoid serious damage which made by thunder and lightning induced tension, electrical network voltage undulation disturbance, static discharge, and impact surge voltage. – Typically used for lightning and surge protection   Feature: 1. Lightning Protector RS485 communication signal surge protector is designed according to the standard of IEC surge protector. 2. The joint form is standard screw grip, it can protect 1~2 groups of circuits.. 3. There are various choices of quota voltage, also, the installation and maintenance is very easy and convenient. 4. 3-levels tandem type, the Maximum discharging current can achieve 10kA, reacting within Picosecond level, it can fully protect those equipments which use the latest semiconductors   Specification: Continuous operating voltage Un = 5V Nominal discharging current In (8/20us) = 5KA Maximum discharging current Imax (8/20us) = 10KA Limit voltage Up = 15V Data transmission rate Vs = 10Mbps Insert loss Ae = 0.2dB Response time Ta = 1nS Joint form = Grip Typically used in = RS485 lightning protection Protection form = Line to line, line to earth Dimension = 25mm x 25mm x 54mm (does not include the joint) Working conditions Temperature = -25— 65; Humidity ≤ 95%(25-30) Expiration pattern = The communication lines are short-circuit or cut off to earth Test standard = IEC61643-21:2000
