High-precision switching systems, converters, and backup modules engineered for global compliance and extreme environmental resilience.
Founded in 2004 and situated within the fast-growing economic hub of Shenzhen, ShenZhen JDI Power Supply Co., Ltd. is a certified national high-tech enterprise. For two decades, we have focused on the custom research, engineering, and precision manufacturing of premium power conversion products, specialized adapters, and industrial-grade uninterruptible power systems.
Operating from a state-of-the-art, independent 6,000 square meter manufacturing base, JDI Power Supply maintains first-class hardware lines and advanced analytical tools. Our commitment to operational excellence is demonstrated by our ISO9001:2008 and ISO14001 certifications, alongside our listing as a New Third Board enterprise. We serve as a strategic supplier to some of the world's most recognized consumer, medical, and industrial electronics brands.
Industrial trends driving the high integration, intelligence, and thermal efficiency of modern power delivery platforms.
Today's industrial landscape demands increased power densities, reduced footprint constraints, and higher efficiency. In regions like North America, Europe, and Northeast Asia, the adoption of Wide Bandgap (WBG) semiconductors (GaN/SiC) has accelerated the transition from discrete power components to integrated, system-in-package power architectures.
This technology shift is evident in key areas such as EV charging infrastructure, medical imaging peripherals, and high-reliability telecom modules. Industrial and utility operators require high-efficiency solutions to lower operating costs and reduce system temperatures. For example, our 11,000W DC-to-DC solar pump converters utilize Maximum Power Point Tracking (MPPT) to operate reliably in harsh conditions. Meanwhile, charging networks transitioning to CCS and NACS standards require adapters with robust thermal management to support sustained 150A/1000V DC fast-charging outputs.
Integrating switching stages, controllers, and magnetic components to maximize output wattage per cubic inch while reducing overall PCB footprint.
Guaranteed compliance with IEC/EN 60601 for medical gear, IEC/EN 62368 for ICT, UL1310 class 2 power limits, and international efficiency regulations like DOE Level VI.
Optimized thermal management and low electromagnetic signature profiles, designed to pass stringent CE, FCC, and VCCI EMC tests without requiring heavy external shielding.
A look at the milestones shaping the next generation of modular power distribution systems.
Wide Bandgap materials reduce switching losses, enabling operating frequencies in the megahertz range. This reduces the size of passive components and allows for more compact power supply designs.
Integrating microcontrollers and standard buses (such as I2C, PMBus, or CAN bus) allows for real-time monitoring of voltage, current, and temperature, enabling predictive maintenance in industrial applications.
The transition of global charging standards toward high-voltage architectures (up to 1000VDC) requires adaptable, liquid-cooled, or high-airflow modules to ensure safety and efficiency during fast-charging cycles.
Our testing processes are designed to ensure long-term reliability and compliance in the field.
Under the direction of an engineering lead with 27 years of specialized experience in power research, JDI Power Supply operates an in-house laboratory equipped with advanced testing systems. We perform comprehensive reliability stress testing to guarantee product performance under demanding conditions.
Our products conform to major international safety and environmental standards:
Custom engineering solutions designed to meet the electrical, physical, and regulatory requirements of specific industries.
Patient safety is the primary requirement in medical electronics. Our medical power adapters conform to IEC/EN 60601-1 standards, offering low leakage currents and 2xMOPP isolation. These products provide stable power for desktop diagnostic consoles and portable ultrasound systems in hospitals worldwide.
Industrial environments often feature unstable voltage lines and wide temperature swings. We manufacture high-voltage converters, buck-boost modules, and MPPT solar regulators to maintain stable power outputs for automation networks and pumping systems.
Smart homes require compact, efficient power conversion. We supply high-efficiency wall chargers, desktop switching power supplies, and multi-rail adapters that comply with IEC/EN 60335 and IEC/EN 62368, helping smart appliance manufacturers meet international efficiency regulations.
To prevent data loss and system downtime during grid disruptions, we engineer high-frequency online and line-interactive UPS solutions. These range from 15W mini-UPS systems for IoT routers to 40kVA online systems designed for IT racks and critical infrastructure.
