Safety precautions:

a) When SPD is installed in final system, it must achieve all the requirements of GB4943 (EN60950, IEC60950) standard;

b)  The equipment has to be installed by authorized professional person,  to avoid incorrect installation or application to influence the normal working and lightning protection of devices

Application

Mainly used to protect the devices from lightning strike and over-voltage damage, which transmit the audio signal by twisted pair

Such as telephone, fax machine, MODEM, exchange, ADSL, ISDN, etc

       Features

1)  Multi stage protective circuit, big discharge current capacity, low residual voltage

2)  International famous core component brand

3)  Low insertion loss, quick response

4)  Precise limiting voltage

5)  19 inch Integrated 16 channels audio signal SPD box

6)  Stable performance, reliable work

7)  Easy installation

Specification

 Installation and wiring

a)   SPD is connected by series between protected devices and signal path

b)   The input side of SPD connects to signal path, output side connects closely to protected device,

c)   To connect ground line of SPD to lightning protection system ground device, lower

connecting wire is better, within 1m
