Explore our core production portfolio—engineered for rugged thermal performance, ultra-high isolation, precise regulation, and seamless integration across industrial, telecom, and automotive platforms.
In modern distributed power architectures (DPA) and intermediate bus architectures (IBA), the selection of isolated and non-isolated DC-DC converter modules directly dictates system reliability, thermal dissipation profiles, and overall power density. As system hardware architects migrate toward higher voltages (such as 48V datacom bus rails and 400V/800V EV traction packs), power supply modules must achieve unprecedented conversion efficiency while maintaining strict electromagnetic compatibility (EMC) and dielectric isolation integrity.
By integrating Gallium Nitride (GaN) and Silicon Carbide (SiC) power MOSFETs into custom OEM modules, switching frequencies exceed 250kHz to 1MHz. This drastically reduces magnetic component volume, enabling compact 1/16th, 1/8th, and quarter-brick modules with power densities surpassing 150W/in³.
Custom potting formulations using high-thermal-conductivity epoxy compounds ensure zero void formation. Conduction-cooled baseplate options and integrated liquid-cooling channels maintain junction temperatures well within derating curves under severe thermal stress (-40°C to +105°C ambient operating environments).
Meeting standard safety mandates (IEC/EN 62368-1, EN 50155, UL 60950), our custom isolated DC-DC modules provide withstand voltage ratings from 1500VDC up to 2250VDC and 4250VDC reinforced insulation, shielding sensitive load ICs from transient high-voltage surges and ground loops.
Global B2B procurement managers and system engineering leads face shifting regulatory landscapes, supply-chain vulnerabilities, and evolving energy-efficiency standards. To maintain competitive advantage, OEM hardware sourcing strategies are adapting to four pivotal industry trends:
Supply chain security mandates second-sourcing compatibility. Modern system procurement prioritizes open-frame and encapsulated modules conforming to Distributed-power Open Standards Alliance (DOSA) footprints—such as 1/32nd, 1/16th, 1/8th, quarter, half, and full-brick dimensions. This allows plug-and-play interchangeability while enabling custom internal magnetic tweaks by specialized OEM suppliers.
With industrial automation utilizing 24V/36V/48V buses, rail applications operating across 72V/110V ultra-wide inputs (16-160V continuous), and electric commercial vehicles adopting 400V/800V battery architectures, procurement trends favor manufacturers capable of delivering wide continuous input ratios (4:1, 8:1, and 12:1 ultra-wide input converters).
Analog PWM control loop modules are rapidly giving way to digitally controlled converter modules equipped with PMBus, I2C, or CANbus interfaces. Real-time telemetry monitoring of input voltage, output current, module temperature, and fault diagnostics allows predictive maintenance in critical telecom base stations and electric fleet vehicles.

Backing over two decades of power electronics design excellence, our factory serves as a turn-key production partner for high-reliability board-mount isolated converters, non-isolated point-of-load (POL) regulators, high-voltage vehicle converters, and specialized telecom inverters.
Our manufacturing plant houses high-speed Yamaha and Fuji SMT placing equipment capable of handling 0201 passive components, fine-pitch ICs, planar transformers, and heavy copper PCBs. Automated Optical Inspection (AOI) and 3D X-Ray inspection prevent solder bridge defects across multi-layer substrates.
To ensure field failure rates well below 50 PPM, every single converter module undergoes high-temperature full-load burn-in screening, thermal shock cycling (-40°C to +125°C), and Highly Accelerated Life Testing (HALT) to uncover stress thresholds prior to mass production.
Operating under certified ISO 9001, ISO 14001, and IATF 16949 quality management systems, we maintain complete component-level lot traceability. All delivered modules strictly adhere to RoHS, REACH, CE, and UL safety standards.
