Safety precautions:

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

c)  The load current of protected equipments should be below 10A, or the product will cut off the power automatically, only to push the black button on   power line terminal to recover

 

Application

AM type DC power SPD is to prevent lightning over-voltage and transient over-voltage from damaging DC power system and equipments, which mainly used in mobile communication base, microwave communication base, telecommunication computer room, factory, airport, finance and securities

Also applied in several DC power system, such as DC distribution board, DC power supply equipment, DC distribution box, electronic information system cabinet and the output terminal of second stage power equipment

 
Features:

1)  Temperature control circuit break technology, built-in over-current protection circuit, to completely keep away from fire disaster

2)   International famous components and advanced manufacturing technique

3)   Big discharger current capacity, low residual voltage

4)   Remote alarm connect point(standard)  

5)   Clear and intuitive working condition

6)   Easy installation and maintain

7)   Exquisite process, can work under the hostile environment for a long time, like acid, alkali, dust, salt fog, wet, etc

Installation

1)  35mm slide guide installation way,

2)   Connect +/- and ground terminal of power system to +/- and ground terminal of SPD, then screw up the bolts

3)   ground line of SPD to lightning protection system ground device

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

 Product maintenance

a)  The equipment has to be installed by authorized professional person, before installation, to cut off power supply, and prohibit hot-line work from accidents

b)  The sectional area of wire must reach technical demands

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

d)   The product does not need to be maintained specially, but to inspect at fixed period

e)   After thunderstorm season, it is normal that the indicator window is red, but to change a new module or total product instantly

f)    Once there is a failure during system operation, please remove the SPD device at first, if the system can operate normally, the device is broken
