Dongguan Rama Charger Technology: Your Trusted ODM/OEM Partner
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.
As a leading 30kW DC power module manufacturer in China, our team possesses strong independent R&D capabilities. We don't just sell hardware; we provide customized core master control boards for charging pile manufacturers worldwide. Our expertise spans across high-frequency power electronics, digital control algorithms, and advanced thermal management.
Headquarters Excellence: Our facility is backed by DEKRA CB, CE, and ISO9001 certifications. Recognized as a "High-Tech Enterprise," we hold over 15 software copyrights and multiple invention patents, ensuring your projects are built on a foundation of legal and technical authority.
Why the 30kW DC Power Module is the Industry Benchmark
The global shift toward "Fast DC Charging" has made the 30kW module the golden standard. It offers the perfect balance between charging speed and grid stability for commercial fleets and public stations.
V2G (Vehicle-to-Grid) and V2H (Vehicle-to-Home) are no longer futuristic concepts. Our bidirectional 30kW modules allow EVs to act as mobile power banks, stabilizing the grid during peak loads.
Modern procurement demands smaller footprints with higher output. Our 30kW modules utilize SiC (Silicon Carbide) technology to reduce heat dissipation needs and increase efficiency to over 96%.
The Dongguan Rama Charger Advantage
Located in Dongguan, the world's electronics manufacturing hub, we have immediate access to top-tier components and raw materials, ensuring shorter lead times and competitive pricing without compromising quality.
Unlike simple assembly plants, Rama Charger owns the core IP. From PCB layout to firmware optimization for OCPP 2.0.1, we control every line of code and every trace on the board.
We maintain a robust AAA credit rating and follow ISO9001 standards rigorously. Every 30kW module undergoes 100% full-load burn-in testing before shipment to guarantee reliability in harsh environments.
End-to-End Support for Your Global Energy Business
Expert advice on charger compatibility, AC/DC requirements, and connector types (CCS1/2, CHAdeMO, GB/T, NACS). We provide site assessment support and regulatory guidance for CE/UL certifications.
Streamlined order management with global logistics handling (Air, Sea, DDP). We provide detailed installation manuals, wiring diagrams, and remote commissioning assistance.
Standard 1–3 years warranty with genuine spare parts supply. We offer 24/7 technical hotlines, operator training sessions, and continuous firmware updates to ensure performance.
In the rapidly evolving landscape of Electric Vehicle Supply Equipment (EVSE), the 30kW DC power module stands out for its high power density and wide output voltage range. Our modules typically support an output from 200VDC up to 1000VDC, making them future-proof for the next generation of 800V battery architectures found in premium EVs.
One of the critical expertise areas Rama Charger brings is Digital Control Technology. By using DSP (Digital Signal Processing), our modules achieve precise current sharing when multiple units are parallelized. This allows for massive 180kW or 360kW charging stacks that operate with high efficiency even at partial loads.
Furthermore, our commitment to Reliability (Trustworthiness) is reflected in our thermal design. We use independent air-duct designs to prevent dust and salt spray from corroding sensitive electronic components, which is vital for coastal installations or industrial environments. This attention to detail is why global procurement managers choose Rama Charger as their primary supplier in China.
Our bi-directional 30kW converters are particularly revolutionary for the "Smart Grid" era. By facilitating Vehicle-to-Grid (V2G) communication, we enable fleet operators to monetize their idle EV batteries, providing a secondary revenue stream while supporting renewable energy integration. This level of professional ODM service ensures our clients stay ahead of the curve.
