As the world pivots toward renewable energy, the stability of Direct Current (DC) systems has become a focal point for engineers and investors alike. The Type 2 DC Surge Protective Device (SPD) is the unsung hero of this transition. Designed specifically to protect electrical installations from transient overvoltages—often caused by indirect lightning strikes or switching operations—Type 2 SPDs are essential for safeguarding photovoltaic (PV) inverters, EV charging stations, and industrial DC power supplies.
In the global commercial sector, the demand for Type 2 DC SPDs has surged by over 25% annually. From the vast solar farms in the MENA region to residential rooftops in Europe, these devices ensure that multi-million dollar investments don't vanish in a millisecond due to a power surge. For industrial operators, a Type 2 SPD is not just a component; it is an insurance policy for uptime and operational continuity.
The industry is moving from 1000V DC to 1500V DC systems to increase efficiency. Our Type 2 SPDs are engineered to handle the thermal stresses associated with 1500V applications.
Integration of IoT sensors into SPDs allows for real-time health monitoring, notifying maintenance teams before a device reaches its end-of-life.
Global procurement standards now favor manufacturers who use RoHS-compliant materials and sustainable production processes.
Foshan SDEV Charger Co., Ltd. is a trusted manufacturer of protective components for photovoltaic systems across the globe. Our experience of working in the electrical industry for more than 30 years allows us to create solar DC components that comply with the latest DC standards.
Through our focus on solar DC protection design, production, and marketing, we can bring brand-building PV protection solutions. With the inheritance of 30+ years of experience in the research and production of DC protection products, we are continuously dedicated to the EV charging field.
Quality is our primary goal. To achieve this, our factory and products comply with UL, SAA, CB, CE, TUV, ISO, and RoHS standards. This commitment ensures the best performance and safety for any Solar, Storage, and EV charging system.
Procurement managers from EPC (Engineering, Procurement, and Construction) firms and wholesale distributors have evolving needs. They require more than just a part number; they need a partner who understands the localized challenges of different regions.
We provide localized solutions, including custom-labeled SPD modules, specialized voltage ratings for specific national grids, and integrated combiner box solutions that save installation time on-site.
Request a Wholesale QuoteAchieving our goals come from formulating new products based on the market demands through our in-house R&D team. Our efforts have led to our first UL508i listed patented DC switch within China and the DC-PV2 DC switch produced for the global market.
With our cutting-edge PV protective products and EV chargers, we aim to create a long-term partnership with many renewables companies. Our R&D center focuses on the "Next Gen" Type 2 DC SPD, which incorporates MOV (Metal Oxide Varistor) and GDT (Gas Discharge Tube) hybrid technology to eliminate leakage current and extend the lifespan of the protector.
Located in Foshan, the heart of China's electrical manufacturing hub, we enjoy unparalleled access to raw materials, ensuring shorter lead times even during global supply disruptions.
Our automated production lines reduce labor costs while maintaining high precision, allowing us to offer wholesale pricing that gives our partners a competitive edge.
Every Type 2 DC SPD undergoes aging tests and impulse current testing before shipment. We don't just meet standards; we exceed them to ensure 100% reliability in the field.
