Explore our top-selling vehicle-grade onboard chargers, high-frequency voltage regulators, and step-up/down modules engineered for critical systems.
The global transition toward carbon-neutral transportation and high-efficiency industrial machinery has accelerated the demand for intelligent, robust, and highly efficient Onboard Chargers (OBC) and DC-DC conversion systems. As modern fleet architectures shift from traditional internal combustion to Hybrid (HEV) and Battery Electric Vehicles (BEV), power electronics are no longer secondary accessories—they are core components that directly govern charging speed, thermal stability, systemic weight, and energy density.
For industrial buyers, global procurement managers, and EV design engineers, identifying reliable OEM/ODM partners in China is critical. Highly specialized environments, such as marine navigation, off-road heavy duty machinery, commercial camper vans (RVs), and utility telecommunications, require customized input/output isolation parameters, IP67/IP68 ingress protection, and smart digital communication bus architectures (CAN bus, RS485). Shenzhen Wemaxpower Technology Co., Ltd. addresses these micro-requirements with engineered reliability.
E-Rickshaws, specialized electric scooters, delivery fleets, and airport service vehicles rely heavily on specialized 48V, 60V, and 72V charging modules. These systems must support high vibrations, thermal swings, and unstable local mains grids while delivering optimal battery-charging profiles.
Extreme environmental challenges demand hermetically sealed, IP67-rated waterproof boost/buck converters and high-amperage smart chargers. Safeguarding continuous power conversion between primary propulsion batteries and secondary house banks without galvanic line failures is vital.
Standard 19-inch 2U telecom cabinets and DC power rooms need isolated low-ripple step-down converters (e.g., 110V/120V to 12V or 5V isolated modules) to guarantee clean DC supply lines for vital communications, reducing electrical interference and signal dropouts.
Our design pipeline pivots toward high-density power architecture, maximizing conversion efficiency, and lowering structural form factors. Below is the multi-generational technological integration path for our power systems.
Moving away from traditional silicon switches, we utilize Silicon Carbide (SiC) and Gallium Nitride (GaN) MOSFETs in our high-voltage chargers and converters. This reduces switching losses by up to 45%, allows higher operational frequencies (>150kHz), and ensures the total volume of magnetics and filter blocks is reduced by over 30%.
Our upcoming generation of high-frequency onboard chargers supports bidirectional power transfer. This allows recreational vehicles and logistics fleets to act as decentralized battery energy storage systems (BESS), backfeeding energy into microgrids during peak demand cycles while maintaining intelligent grid sync protocols.
Environmental longevity is achieved through vacuum-epoxy potting technologies. Our DC-DC chargers and converters maintain continuous thermal dissipation and complete liquid/gas protection, ensuring performance under saline, humid marine operations and heavy dust mining sites.
Equipping power modules with J1939 CAN protocol allows real-time diagnostics, over-voltage/under-voltage alarm notifications, dynamic output regulation, and telemetry streaming to central processing units, maximizing diagnostic coverage (FMEA) across systems.
Boasting over 7 years of specialized manufacturing experience in the industrial power electronics sector, Shenzhen Wemaxpower Technology Co., Ltd. has established itself as an innovative benchmark. Our production catalog spans programmable DC power supplies, heavy-duty DC-DC converters, telecom-grade sine wave inverters, and high-frequency battery chargers.
We serve thousands of industrial customers across Europe, North America, Southeast Asia, and Australia. Our factory facility maintains high-capacity assembly systems, and our design division features engineers specializing in electromagnetic compatibility (EMC), high-frequency magnetics, and thermal engineering.
Modern power topologies require modular configurations to integrate into diverse industrial applications. Below is how our technology addresses key macro sectors globally.
For warehousing lifters, material handling AGVs, and heavy electric mining trucks, charging systems must operate continuously. Our chargers provide isolated CC/CV algorithms, protecting vehicle battery management systems (BMS) from surge hazards while minimizing downtime during shift turnovers.
Campers, RVs, and marine yachts combine solar charging, alternators, and shore power. Our DC-DC chargers (such as the 12V to 12V 60A models) stabilize these multiple inputs, ensuring correct voltage profiles for lithium LiFePO4 batteries without overloading vehicle alternators.
For auxiliary systems in grid stations and telecom towers, Wemaxpower offers 2U pure sine wave power inverters and isolated converters. These units isolate high-voltage surges from the load, delivering clean power and keeping critical infrastructure online.
