DC SPD
As a power protection expert with nearly 30 years of R&D experience, Zhejiang Dongan Electrical Co., Ltd. is committed to providing global customers with high-standard, high-reliability DC circuit safety solutions. Our DC SPD series is specifically designed for photovoltaic power generation systems, energy storage, and industrial DC power distribution. It can rapidly discharge current during lightning strikes or operational overvoltages, ensuring the safety of expensive downstream equipment (such as inverters and battery packs).
Why Choose Dongan Electrical?
Authoritative Certifications and Quality Assurance:
All products are CE, CB, TUV, and CCC certified, and our laboratory has RoHS 2.0 testing capabilities. Our factory has obtained ISO9001, ISO14001, and ISO45001 system certifications, ensuring that every SPD can withstand rigorous environmental testing.
Deep R&D Accumulation:
Leveraging nearly 30 years of experience in electrical design and manufacturing, we possess fully automated production lines and advanced testing equipment (such as short-circuit current testers and overload testers). Our product designs prioritize environmental protection, safety, and flame retardancy.
One-Stop Supply Capability:
In addition to DC SPDs, we also provide matching DC MCCBs (Modified Case Circuit Breakers) and mold processing services, offering you complete DC power distribution protection solutions.
Exceptional Service Pursuit:
We consistently strive for "As Good as It Gets," providing highly competitive prices and rapid supply to help our customers achieve win-win results in the photovoltaic and industrial power markets.
Friendly Reminder: When selecting a DC SPD, please ensure that the system's maximum continuous operating voltage $U_c$ is higher than the system's open-circuit voltage.
