Safety precautions:

a)   When the SPD box 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, before installation, to cut off power supply, and prohibit hot-line work from accidents  

 

 Function and theory

AJ2CH type 2 in 1 SPD, integrated by Power SPD, network signal SPD, is used to protect surveillance system sensitive to electromagnetic interference, from damaging by lightning induced voltage, power interference and electrostatic discharge.

 

Application

1)   The device (power cable, net cable) of surveillance system

2)   Bank surveillance system and housing district safety system

3)   School, enterprise and road safety protection

 

Feature

1)   Camera power + network multi stage protective circuit

2)    International famous core component brand

3)    High discharge current capacity, low insertion loss, superior transmission performance, no leakage current

4)    Low residual voltage, perfect protective effect

5)   Quick response, stable performance, reliable working

6)   Small size, easy installation

Installation and wiring

1)  According to protection demands, the SPD is connected by series between protected devices and signal path, the closer the distance to protected devices, the better the protection effect.

2)  To connect separately a)the cable to the input terminal of power, net port, b) output terminal of SPD power, net to related interface of protected devices, c) ground line of SPD to earth wire of lightning protection system

3)  After wiring, please check it until everything is going well, to put into operation.
