DC 48v power surge protector with deterioration indicator
Product description & Features & Application
This SPD is applied to provide fine over voltage protection of electronic equipment whose power is supplied by direct-current power supply. It is D-level over voltage protec- tion device, is design according to IEC and GB standard, is available in a variety of differ- ent power supply voltage and selector corresponding specifications.
◆ The product is use for lightning protection zone: LPZ3 (D class) power lines of the lightning surge protection.
◆ It uses high temperature resistant plastic with excellent tightness, and easy to install wiring.
◆ Adopt temperature control circuit technology which has built-in over current breakers and thermal fuse circuit breakers, automatically trip because of deterioration.
◆ this unit is modular deterioration instructions and flame-retardant shell.
◆ It has 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 bus bar microwave communications room, closing the substation bus,control bus.

Product dimention and diagram
1.The lightning arrester is connec- ted 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 conn- ected with grounding line; the way of wiring is the screw tight solid type.
3.All wiring must be solid and con- nect by electric. SPD grounding line: BVR≥mm².
4.Lightning proof grounding should be consistent with lightning prot- ection regulatory requirements, grounding wire should be as thick and short as possible, resistance should be less than 4Ω.
