Select DC SPD By System Voltage
Voltage matching is the first step when selecting a DC surge protective device.
1500V DC SPD
For utility-scale PV plants and high-voltage inverter DC inputs.
1000V DC SPD
For common solar PV strings, combiner boxes, and inverter protection.
600V DC SPD
For selected PV systems, DC cabinets, and lower-voltage DC circuits.
12V / 24V / 48V DC SPD
For telecom, off-grid, battery, monitoring, and control systems.
Choose By Protection Level
Match DC SPD Type With Installation Position
Different DC systems require different surge discharge capability and protection coordination.
Selection Notes
What To Confirm Before Choosing A DC SPD
Send these parameters if you need help matching the right DC surge protection device.
- System voltage: 1500V DC, 1000V DC, 600V DC, or 12V / 24V / 48V DC.
- Product series: High-voltage PV DC SPD, compact DC SPD, or low-voltage DC SPD.
- Schutzart: Type 2 DC SPD for common surge protection, or Type 1+2 DC SPD for higher lightning exposure.
- Electrical parameters: Ucpv, In, Imax, Iimp, Up, pole configuration, grounding type, and cabinet layout.
