Function: |
|
RX-SPD12V lightning protector 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. RX-SPD12V 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 series type, the Maximum discharging current can achieve 10kA, reacting within Picosecond level, it can | |
fully protect those equipments which use the latest semiconductors | |

Installation and Maintenance: | |
1. The surge protector device should be linked between the signal line and the protected equipment. | |
Connect manner is: 1 to 1, 2 to 2.(the follow picture is the example) | |
2. "In" must be connect the signal line;"Out" must be connect the protected equipment, do not connect in the | |
opposite direction. | |
3. The PE line of the lightning arrestor must strictly be connected to the lighting protection system at the | |
equipotential, else, it will influence the working performance. | |
4. Credibly connect the grounding lines. This product need not pay special attention to maintenance, but please | |
waterproof notice. When the system working goes wrong, please check the surge protector after removing it. If | |
unused thesurge protector condition,but the system working normal, meaning the surge protector is damaged, | |
please change the surge protector. | |
