High-efficiency converters, heavy industrial switching supplies, and custom smart chargers engineered to support clean-tech & factory automation applications.
As modern power electronics transition towards higher power density and digitised topologies, Wemaxpower positions itself at the cutting edge of industrial conversion solutions.
Traditional silicon MOSFETs are facing physical thermal boundaries. The incorporation of Gallium Nitride (GaN) and Silicon Carbide (SiC) switches enables elevated switching frequencies (exceeding 200 kHz). This results in a drastic reduction in magnetic core sizes, allowing power densities to reach up to 40W/in³ while keeping thermal dissipation at absolute minimums.
Moving away from analog PWM controllers, next-generation relay power supplies leverage high-speed DSPs (Digital Signal Processors). This facilitates real-time programmable loop compensation, complex battery charging curves (CC/CV/Float for LiFePO4, Lead-Acid, Lithium-Ion), and communication protocols such as Modbus, CAN Bus, and PMBus for industrial IoT telemetry.
To eliminate high-frequency common-mode noise and safeguard upstream electronic components, our architectures leverage high-voltage optocouplers and planar transformers. Multi-phase interleaving techniques distribute thermal stress and cancel output ripple currents, ensuring a clean DC output signal under dynamic transient loads.
Tailoring conversion architectures to the demanding requirements of harsh, modern industrial environments.
Stable voltage regulation for PLCs, solenoid valves, contactors, and relays. For applications like electroplating switching, our systems take a 380Vac 3-phase input and provide high-power adjustable DC outputs (up to 250V/40A) featuring digital regulation and robust short-circuit protection.
Industrial vehicles, electric forklifts, golf carts, and recreational vehicles require high-durability converters. Our isolated DC-DC modules and step-up regulators ensure clean power conversion (e.g., 24V to 48V boost, 12V to 48V boost) despite heavy alternator noise and battery voltage fluctuations.
Precise multi-stage charging algorithms for LiFePO4, Lead-Acid, and Lithium-ion chemistries. Dynamic thermal monitoring prevent thermal runaway, extending overall battery lifecycle and efficiency in off-grid solar storage networks.
Shenzhen Wemaxpower Technology Co., Ltd. is a leading OEM/ODM manufacturer with 7 years of industrial experience in programmable DC power supplies, converters, and specialized charging modules.
To meet international quality standards and ensure long-term field reliability, every unit we produce undergoes a strict 4-step QC pipeline:
Incoming screening of capacitors, inductors, diodes, and semiconductor chips to verify electrical tolerances.
Automated Optical Inspection (AOI) and circuit pathway verification after surface-mount technology (SMT) assembly.
Comprehensive validation of load regulation, ripple coefficients, conversion efficiency, and protection threshold triggers.
100% full-load dynamic thermal stress testing inside chambers for up to 48 hours to weed out early-life failures.
A guide for industrial procurers and global distributors to evaluate China supply chain capabilities.
Industrial markets require rigorous standards compliance. Wemaxpower power supplies and converters are designed to meet CE, FCC, RoHS, and REACH guidelines. Features like galvanic isolation (up to 3000Vac input-to-output) and robust EMI filters ensure compliance with electromagnetic standards for marine, automotive, and IT environments.
For applications such as golf carts, marine vessels, and industrial forklifts, standard power supplies often fail due to moisture, dust, and vibration. Wemaxpower uses high-performance thermal potting compound inside anodized aluminum housings, achieving IP67 dust and water resistance, high vibration immunity, and efficient conduction cooling.
Global procurement teams often need customized voltage step-up/down ratios or specific smart charging profiles. Our R&D team supports tailored design requests—including custom variable output limits, specific enclosure form factors, dynamic dimming capabilities, and specialized cable assemblies.
Expert technical answers to key questions regarding DC-DC converters, programmable power supplies, and battery chargers.
Isolated converters use an internal high-frequency transformer to separate the input and output circuits electrically, preventing input voltage spikes from damaging the output load. They block common-mode noise and ground loops. Non-isolated converters share a common negative ground, offering higher efficiency and a smaller foot print at a lower cost point. They are ideal for applications where input-to-output isolation is not safety-critical.
First, Incoming Quality Control (IQC) tests component tolerances. Second, In-Process Quality Control (IPQC) uses automated optical inspection (AOI) to find solder bridging and placement issues. Third, Final Quality Assurance (FQA) tests the output values and safety interlocks under full load. Finally, our dynamic high-temperature burn-in test runs components under full load to weed out infant-mortality component failures prior to shipping.
Water, moisture, and road dust can short-circuit high-voltage electronics. An IP67 enclosure is fully sealed using epoxy potting. This protection prevents humidity from condensing on component pins, isolates internal traces from conductive dust, and improves heat conduction from hot magnetic components to the outer aluminum shell.
Electroplating processes require smooth, constant DC currents to ensure even metal deposition. Our adjustable 380Vac 3-phase switching power supplies feature very low output ripple and precise voltage/current limit programming, helping prevent deposition defects and ensuring uniform coating thickness.
