Power Supply Surge Protective Device

 

Product introduction:

SDZ100-50 is class 1 switch-type surge protection. It can effectively release the incoming and inductive lightning on the low-voltage line of system, and effectively protect power supply equipment from lightning strike.
 
 
Characteristic:
1/ Impulse current reaches 10/350μs 60kA;
2/ Low voltage limitation;
3/ Nominal discharge current reaches 8/20μs 200kA;
4/ Strong capability to cut off residual current;
5/ Discharge monitor is applicable to configurate with RS485 communication.
 

Installation:

1/ Install on 35mm rail;

2/ It is necessary to series connect a fuse or air switch with SPD.

 
Maintenance:
SPD should be inspectied and maintenance in reuglar basis, pls duly replace SPD if it is red color in display window.
