Engineered for High Density, Thermal Stability, and Severe Voltage Regulation Demands
Shenzhen Wemaxpower Technology Co., Ltd. stands at the forefront of power conversion engineering. With over 7 years of specialized R&D experience, our factory delivers customized Isolated DC-DC Converters, programmable DC power supplies, active PFC switching units, and heavy-duty battery chargers to system integrators worldwide.
In modern industrial systems, non-isolated power supplies often expose sensitive microcontrollers and telemetry nodes to high-voltage transients, ground loops, and electrical noise. Our high-frequency transformer isolation topologies physically break ground paths, protecting critical loads across electric transportation, telecommunications, marine vessels, and automated industrial plants.
Every single power unit undergo a mandatory, rigorous 4-Step Quality Control (QC) Process before leaving our facility:
Why Tier-1 Automotive and Industrial Engineers Depend on Wemaxpower Isolated Power Conversion Platforms
Incorporating high-frequency planar transformers and optocoupled feedback loops, our isolated converters provide up to 1500VDC–3000VDC isolation voltage between input and output circuits. This eliminates dangerous common-mode ground noise and safeguards delicate digital controllers against destructive voltage spikes.
Supporting multi-voltage battery banks (from 9-16V, 24V, 36V, 48V, up to 72V and 220VDC switching inputs), our power converters integrate active Power Factor Correction (PFC > 0.99), maintaining continuous full-power throughput even during extreme battery discharge cycles.
Engineered for harsh ambient environments, our fully potted aluminum extruded enclosures achieve IP68 ingress protection. They resist vibration, moisture, saltwater exposure, corrosion, and extreme thermal operating conditions ranging from -40°C to +85°C.

Providing Uninterrupted Power Regulation Across Demanding Global Markets
In electric wheelchairs, golf carts, patrol cars, and urban delivery vehicles, high-voltage traction batteries (36V-72V) must step down efficiently to supply 12V auxiliary electronics, lighting, dashboard telemetry, and braking systems. Our 1000W–1200W buck modules deliver stable current without thermal throttling.
Saltwater spray and severe chassis vibration pose risks to standard off-the-shelf electronics. Our IP68 sealed battery-to-battery (B2B) chargers (such as 12V to 14.6V LiFePO4 chargers) continuously replenish auxiliary battery banks safely, operating reliably in boat engine compartments and campervan chassis.
Modern telecommunications hubs and high-voltage power substations require clean 48VDC power from high-voltage DC (220VDC) backbones. Our 2U 19-inch rack-mount isolated converters provide low-ripple output with N+1 hot-swappable redundancy options for uninterrupted uptime.
Situated in the heart of Shenzhen’s electronic design cluster, Wemaxpower Technology leverages direct integration with top-tier tier-1 semiconductor suppliers, magnetic component fabricators, and automated SMT production facilities.
Our localized supply chain infrastructure yields significant competitive advantages for OEM/ODM engineering partners globally:

Our power engineers model the high-frequency switching circuit, design custom planar magnetics, and simulate thermal dissipation using 3D CAD modeling.
Golden sample manufacturing undergo comprehensive bench testing: short-circuit protection, transient response, EMI/EMC compliance, and thermal stress tests.
Full production rollout under automated SMT line supervision, ending with our mandatory 100% 4-step quality assurance and load burn-in verification.
Pioneering Next-Generation High-Power Density Electronics with Wide Bandgap Semiconductors
Transitioning from silicon MOSFETs to Wide Bandgap (WBG) Gallium Nitride (GaN) and Silicon Carbide (SiC) power devices enables switching frequencies in excess of 500 kHz. This reduces planar transformer size while raising energy efficiency past 97%.
Replacing analog PWM controllers with ARM/DSP digital loops allows real-time programmable output profiling, thermal auto-derating, adaptive switching regulation, and CANbus/Modbus integration for Industry 4.0 IoT telemetry monitoring.
By leveraging ceramic multi-layer substrates, high thermal conductivity aluminum PCBs, and direct potted liquid cooling interfaces, power density ratings continue to expand, cutting total enclosure volume by over 40% for space-constrained installations.
