Photovoltaic Power SPD
(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 is use for lightning protection zone: LPZ2 area at the junction with the LPZ3 (D class) power lines of the
lightning surge protection.
◆It is use for 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.
◆It is designed modular deterioration instructions, flame-retardant shell.
◆It has dustproof, anticorrosion and other functions.
◆It is used in a relatively harsh environment staying a long-term stability
◆The remote signal port can achieve remote alarm control.
◆It is widely used in the DC power lightning protection of solar power systems, mobile communication base stations,
microwave communications bureau, telecommunications room, plant, civil aviation, finance, securities and other system.

(3)Product Installation:
1. The lightning arrestor is connected with the power lines in series, which is 35 mm standard rail mounting.
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 wiring must be solid and connect by electric. SPD cable: BVR≥6mm2, grounding line: BVR≥10mm2.
4. Lightning proof 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.The grounding wire of lightning arrestor
is connected with the lightning protection system grounding row, when installation wiring is complete,
check the wiring correctly and securely, then connect the power supply, the SPD can be put into use.
