This SPD is applied to provide fine overvoltage protection of electronic equipment whose power is supplied by direct-current power supply.

1)Product Description:

This SPD is applied to provide fine overvoltage protection of electronic equipment whose power is supplied by direct-current power supply.It is D-level overvoltage protection device, is design according to IEC and GB standard,is available in a variety of different power supply voltage and selector corresponding specifications.

The product apply to lightning protection zone: LPZ2 area at the junction with the LPZ3 (D class) power lines of the lightning surge protection.

Apply to high temperature resistant plastic with excellent tightness , and easy to install wiring.

Adopt temperature control circuit technology which has built-in overcurrent breakers and thermal fuse circuit breakers, automatically trip because of deterioration.

With modular deterioration instructions and flame-retardant shell.

With dustproof, anticorrosion and other functions.

It is used in a relatively harsh environment staying a long-term stability

It is widely used in the lightning protection of telecommunications room DC bus, the DC busbar microwave communications room, closing the substation bus, control bus.

3)Product installation:

1. The lightning arrestor is connected with the power lines in series, then with the ground network.

2.When installation,inlet and outlet terminal of lightning protection devices will be connected with"+","-"pole of the corresponding DC power ; "PE" symbol is connected with grounding line; the way of wiring is the screw tight solid type;

3.All wirings must be solid and connect by electric.SPD cable: BVR≥6mm², grounding line: BVR≥10mm².

4.Lightningproof grounding should be consistent with lightning protection regulatory requirements, grounding wire should be as thick and short as possible,resistance should be less than 10Ω.
