In the rapidly evolving landscape of global electrification, the demand for robust power quality has never been higher. As a premier OEM/ODM Surge Arrestor Type 2 Manufacturer, we recognize that Type 2 Surge Protective Devices (SPD) are no longer optional—they are the secondary line of defense essential for protecting sensitive electronic equipment from transient overvoltages. Whether in commercial complexes, industrial plants, or EV charging stations, the Type 2 Surge Arrestor serves as the critical gatekeeper against indirect lightning strikes and switching surges.
Unlike standard generic components, our Type 2 Surge Arrestors are engineered using advanced Metal Oxide Varistor (MOV) technology combined with high-capacity Gas Discharge Tubes (GDT). This hybrid approach ensures a lower voltage protection level (Up) while maintaining high discharge current capacities (In/Imax).
Modern SPD solutions now include remote signaling contacts. As a leading factory, we integrate IoT-ready modules that allow facility managers to monitor the health of their surge protection in real-time, preventing downtime before it occurs.
Enterprises in Europe, North America, and Southeast Asia are increasingly mandating IEC 61643-11 and UL 1449 compliance. Our ODM services bridge the gap between regional electrical standards and high-volume manufacturing efficiency.
Dongguan Rama Charger Technology Co., Ltd. is a technology-driven enterprise integrating R&D, design, manufacturing, sales, and service into a seamless operation. We specialize in providing comprehensive system energy solutions for electric vehicle charging and related applications.
With strong independent R&D capabilities in charging controllers, Rama Charger can provide customized core master control boards for charging pile manufacturers. Over the years, we have established collaborations with numerous leading charging pile enterprises domestically and internationally, delivering outstanding ODM results and tailored solutions.
Our headquarters has obtained multiple authoritative certifications, including DEKRA CB, CE, ISO9001, as well as recognition as a high-tech enterprise and technology SME. We maintain a robust quality management system and AAA credit rating, and have secured 15 software copyrights, multiple invention patents, utility model patents, and design patents, reflecting our commitment to innovation and excellence.
Our Surge Arrestor Type 2 solutions are integrated into high-density power environments. By utilizing a modular design (pluggable cartridges), we allow for maintenance without interrupting the power supply. This is a critical requirement for data centers and healthcare facilities where "Zero Downtime" is the operational benchmark.
As an expert in EV chargers, Rama Charger integrates Type 2 SPD protection directly into our 120kw-160kw DC Fast Chargers. This prevents damage from grid switching transients, extending the lifespan of the EVSE by up to 40%.
As a global Surge Arrestor Factory, we navigate the complex landscape of international standards. Our products are tested to meet:
We provide localized technical documentation and multilingual support to ensure your regional installers have the precise data needed for safe integration.
