               KNFG Series PV DC Current SPD

 

KNFG series PV DC current SPD is suitable for protection of the solar electrical energy generation system or other DC power system

 and to protect the system from damaging of lightening over voltage.

 

·The indicator adjusts from green to red when this system malfunctions.

·Needn't to consider the load current and Plug design, easy to  maintenance,With Monitor and the tripping device.

·Using the temperature control open circuit technology.

·With The remote warning device (S type) and be Convenient for remote monitoring.

Installation and Maintenance

1.DIN 35MM standard rail installation

2.The product adopt the flame - retardant ABS housing,fix the products,connect the power lines and ground lines,examine and power 

   up.

3.Grounding is very important to the normal work of SPD.the ground contact area is no less than 25 mm2 and as short as possible.

4.the products don't need special maintenance while it is on position for a long time.So we should assign some people to examine 

  regularly.Especially in The thunderstorm season.Once stuck,check it Immediately.

5.The product is equipped with a fault indicator.when working correctly,the indicator shows green,When this system malfunctions,

   it shows red.

6.The internal components is with alternating current,be careful when the system is working.
