Engineered for excellence, our surge protection devices (SPDs) offer unrivaled safety for photovoltaic and industrial DC systems.
In the modern industrial era, the transition from AC to DC power systems is accelerating. From the massive Utility-scale Solar Farms in the deserts of the Middle East to the Hyper-scale Data Centers in Northern Europe, the demand for reliable DC Power Surge Protector Manufacturers has never been higher. As lightning strikes and switching transients pose significant risks to sensitive electronics, the global market for DC surge protection is projected to reach billions by 2030.
Industries such as Telecommunications (5G), Electric Vehicle (EV) Charging Infrastructure, and Battery Energy Storage Systems (BESS) are driving a critical need for localized, high-performance protection. Enterprises worldwide are no longer looking for "off-the-shelf" parts; they are seeking OEM partners who can provide tailored solutions that withstand extreme environmental conditions.
Staying ahead of the technology curve with smart features and higher voltage thresholds.
The industry is moving from 1000V to 1500V to increase efficiency. Our latest SPDs are designed to handle these higher stresses with enhanced thermal stability.
IoT-integrated surge protectors now allow real-time status monitoring, notifying operators before a device reaches its end-of-life (EOL).
Combining MOV and GDT technologies to provide low residual voltage and high discharge capacity for maximum equipment safety.
Foshan SDEV Charger Co., Ltd. is a leading DC Power Surge Protector Factory with a rich heritage in electrical protection. With over 30 years of deep-rooted experience, we have evolved from traditional electrical component manufacturing to a global powerhouse in Solar DC components and EV charging protection.
Our facility is equipped with state-of-the-art testing labs to ensure every batch of SPDs meets the rigorous standards of UL, SAA, CB, CE, TUV, ISO, and RoHS. We don't just manufacture products; we build partnerships that help global brands secure their energy infrastructure.
When global enterprises source DC Surge Protectors, they prioritize three things: Reliability, Certification, and Scalability. As a premier Chinese manufacturer, we bridge the gap by providing high-end technology at competitive costs.
Our first UL508i listed patented DC switch within China is a testament to our innovation. We continuously update our designs based on real-world market feedback.
From raw material sourcing of Varistors (MOVs) to the final assembly, every step is logged and monitored for 100% quality assurance.
We provide full white-label services, customized branding, and specialized electrical parameters to meet your specific local grid requirements.
Integrated solutions for smart junction boxes and advanced lighting protection.
As the world pivots toward electrification, DC power has emerged as the primary energy medium for renewables and storage. However, the inherent characteristics of DC circuits—specifically the lack of zero-crossing points compared to AC—make quenching arcs and managing surges significantly more challenging. This is why choosing an expert Custom OEM DC Power Surge Protector Manufacturer is paramount for modern infrastructure safety.
At SDEV, our engineering team focuses on advanced thermal disconnect mechanisms. In the event of an SPD failure due to overheating or prolonged overvoltage, our devices are designed to safely disconnect from the circuit, preventing potential fire hazards—a critical requirement for UL and TUV certified factories.
Grid standards vary significantly between regions like North America (UL 1449) and Europe (IEC 61643). As an OEM DC SPD factory, we provide localized engineering support. Whether you need a specific Imax (Maximum Discharge Current) for lightning-prone areas or a lower Up (Voltage Protection Level) for sensitive data circuits, we can adjust our module designs to suit your local application scenario.
Telecommunication towers are often located in remote, high-altitude regions, making them prime targets for lightning strikes. Our DC surge protection modules are integrated into 5G power distribution units (PDUs) worldwide, ensuring that the backbone of global communication remains uninterrupted. By utilizing high-capacity MOVs and robust IP65-rated enclosures, we provide a "set and forget" solution for telecom operators.
Beyond technical performance, Foshan SDEV Charger Co., Ltd. is committed to the environment. Our production processes strictly adhere to RoHS standards, ensuring that our products are free from hazardous substances. We believe that protecting green energy equipment should be done with green manufacturing practices.
