With 7 years of deep-rooted expertise in R&D and manufacturing, Wemaxpower has established itself as an innovative force in the power electronics industry. Our comprehensive catalog ranges from programmable DC power supplies and dynamic high-efficiency DC-DC converters to specialized industrial power modules.
We target the complex requirements of high-demand markets across Europe, the Americas, and the Asia-Pacific region. By prioritizing strict compliance metrics, multi-protocol system integration, and advanced thermal management, we empower developers, engineers, and supply chain managers with rugged hardware optimized for 24/7 industrial performance.
All our manufacturing operations comply strictly with European Union safety directives. The CE Certification (comprising LVD 2014/35/EU and EMC 2014/30/EU) ensures that our programmable systems integrate smoothly without posing harmonic distortion or safety hazards to surrounding industrial facilities.
From the conceptual prototyping phase through NPI (New Product Introduction) to high-volume assembly lines, every module is optimized for efficiency, transient response time, and thermal dissipation, lowering the Total Cost of Ownership (TCO) for our global business partners.
Explore the engineering systems, control protocols, and hardware architectures that drive our products.
Our systems utilize advanced Active Power Factor Correction (PFC) circuitry. This optimizes mains current utilization and achieves a power factor of up to 0.99. High efficiency (>87% to 96%) reduces operational thermal load and guarantees stable performance even when utility grids experience voltage sags.
Whether running simulation runs for variable battery packs or high-load industrial burn-in procedures, our power supplies deliver smooth constant voltage (CV) and constant current (CC) operations. Dynamic programming interfaces allow real-time control via 0-5Vdc remote analogs, Modbus, or RS232/RS485.
Constructed within high-grade extruded aluminum alloy housings or standard 19-inch 2U rack enclosures, our systems handle demanding physical environments. IP67-rated waterproof versions prevent moisture and dust ingress, making them suitable for vehicles and marine applications.

How engineers deploy our programmable supplies and DC-DC converters in real-world facilities.
With the rapid adoption of electric mobility worldwide, testing onboard chargers, DC-DC converter modules, and high-capacity battery management systems (BMS) demands stable, programmable DC power inputs.
By utilizing our 18KW high-power adjustable DC supplies, engineers can simulate real-world battery discharge curves and transients. This allows testing of compliance benchmarks under variable voltages (ranging from 160V up to 500V) in localized testing centers across Germany, North America, and Japan.
Solar microinverters require precise Maximum Power Point Tracking (MPPT) verification. Our programmable systems can be configured to act as solar array simulators.
By controlling voltage and current via analog 0-5Vdc or RS485 interfaces, local testing laboratories can simulate solar irradiance shifts. This helps confirm that grid-tied solar systems operate safely and comply with local utility grid requirements.
Marine vessels and RV conversion setups operate in highly demanding, isolated environments. Our IP67-rated waterproof DC-DC converters (such as the 24V to 48V 50A 2400W step-up boost converter) manage these environments effectively.
These converters provide isolated, stabilized voltage outputs, preventing damage from engine alternator surges and keeping communication equipment, safety systems, and lithium battery banks operational.
19-inch 2U rack-mounted systems are standard in municipal automation, data centers, and telecom infrastructure. Our 220Vdc to 48Vdc DC-DC converters fit seamlessly into standard telecom racking systems.
They provide stable secondary distribution voltage with built-in protections for over-temperature, short-circuits, and input under-voltage, reducing unscheduled maintenance downtime.
How our production team maintains low field-failure rates through systematic validation.
Incoming checks (IQC) inspect all key active components, high-density magnetic cores, and premium capacitors to ensure compliance with our strict reliability standards.
After SMD assembly and wave soldering, boards undergo automated testing to verify gate driver signals, isolated feedback loop parameters, and thermal signatures.
Completed systems are evaluated for tracking precision, output ripple, interface functionality (Modbus/Analog), and compliance with CE-EMC/LVD insulation benchmarks.
Every single power unit runs under full-load thermal stress inside our specialized aging chambers to eliminate early failures, ensuring long-term operational stability.
Leveraging local infrastructure to deliver reliable, high-performance power solutions globally.
Located in Shenzhen, the global hub for power electronics manufacturing, we enjoy direct access to component suppliers, raw materials, and magnetics manufacturers. This geographical advantage helps minimize lead times and insulates our customers from supply disruptions.
Our facilities support swift modification of standard designs. Whether you require specific voltage adjustment ranges, custom programming protocols (CAN bus, Ethernet), or high IP-rated enclosures, our engineering team can quickly provide working prototypes.
By optimizing assembly operations and utilizing automated testing systems, we offer high-performance power solutions at competitive prices. This helps you lower engineering overhead and reduce total project expenses.
Providing certified and verified industrial power solutions to global markets.
How we integrate next-generation semiconductor materials and intelligent control systems.
To achieve high power density in compact 2U enclosures, we are transitioning our high-power programmable DC models from silicon IGBTs to Silicon Carbide (SiC) MOSFETs. SiC technology enables higher switching frequencies, reduces thermal dissipation losses by up to 35%, and allows for smaller magnetic filter designs. This results in quieter operation and a smaller, more space-efficient overall package.
Modern automated manufacturing requires flexible control interfaces. Our upcoming technology generation features an integrated ARM-based DSP controller with dual-loop capabilities. This design supports real-time monitoring and parameter adjustments via CAN FD, EtherCAT, and Modbus TCP interfaces. Users can easily update firmware, program complex ramp profiles, and configure safety thresholds via remote control.
