AC & DC SPD series for low-voltage systems

Surge Protective Device Manufacturer for AC & DC SPD Series

OOHMAGE manufactures and supplies surge protective device (SPD) series for low-voltage distribution boards, industrial panels and selected DC applications. Buyers can compare the main AC and DC surge protection device families, then confirm model details, quantity and documents before ordering.

AC and DC Surge Protective Device Series

OOHMAGE keeps this page close to a product category page: buyers first review the main surge protective device series, then confirm the exact model, rating, poles and required documents during inquiry.

SPD Project Selection and Quotation Support

OOHMAGE supplies surge protective device (SPD) series for AC and DC electrical panels, power distribution systems, solar-related applications and project procurement. Buyers can compare Type 1, Type 2 and Type 1+2 SPD options according to system voltage, pole configuration, discharge-current requirements, AC/DC application and installation environment.

For SPD price confirmation or quotation, send the required protection type, system voltage, AC or DC application, pole number, nominal or maximum discharge-current requirements, quantity and destination market. Certification and technical document support can be discussed according to the confirmed SPD series and order requirements.

SPD Quotation FAQ

What information is needed for an SPD quotation?

Share the protection type, AC or DC voltage, pole configuration, discharge-current requirements, quantity, destination market and installation application. If the SPD is used in a solar, industrial or outdoor project, include the installation environment as well.

How do I choose between Type 1 and Type 2 SPD?

Type 1 SPD is typically selected for higher-energy surge protection at incoming distribution level, while Type 2 SPD is commonly used for distribution panels and downstream transient overvoltage protection. The final choice depends on the system design and project requirements.

Can OOHMAGE support AC and DC SPD model selection?

Yes. OOHMAGE can support model confirmation for AC and DC surge protective device applications after the voltage, poles, protection type and discharge-current requirements are provided.

Choose an SPD by Protection Type and Application

Type 1 SPD is used where higher-energy surge protection is required at the incoming distribution level. Type 2 SPD supports distribution panels and downstream protection against transient overvoltage. Type 1+2 SPD combines coordinated high-energy and downstream surge protection.

For AC or DC selection, confirm the system voltage, pole configuration, installation location and the published parameters of the selected model before ordering.
