Explore our engineering-grade switching power supplies featuring high stability, wide voltage adjustment, and advanced safety standards.
In modern industrial applications, electric power management is not just about transformation; it is about performance sustainability, reliability, and extreme adaptability. As a premier CE-certified modular power supply manufacturer and exporter based in Shanghai, we provide cutting-edge solutions designed to resolve complex electrical challenges. Over 15 years of focused engineering in high-power regulated systems has allowed us to deliver a complete line of AC-DC and DC-DC power supplies. These architectures provide robust, regulated, and variable outputs ranging from 12V to over 1000V, supporting power capacities up to 24000W.
Our power supplies are designed to withstand transient overvoltages, load fluctuations, and harsh electromagnetic interference (EMI) typical of industrial environments. By incorporating modular configurations, we offer scalable architectures that allow developers to connect units in parallel for greater current capability or in series to achieve higher voltage ceilings. This modular philosophy increases operational MTBF (Mean Time Between Failures) and minimizes costly system downtimes.
Tailored power integration across critical sectors ensuring seamless operational continuity and electrical efficiency.
Designed for battery packs, providing high-efficiency constant-current and constant-voltage (CC/CV) profiles up to 16,000W with safety mechanisms.
Offering continuous performance for heavy-duty drive systems, multi-axis motion controls, and high-voltage DC distribution grids.
High-precision, ripple-free adjustable benchtop options for simulated component testing, electroplating, and scientific R&D fields.
Our solutions adapt to the demands of modern grid integrations. Across regions, modular architectures allow dynamic balancing of phases and load configurations. We implement built-in active power factor correction (PFC > 0.95), optimizing input power efficiency and decreasing unwanted harmonics in municipal electrical systems. This design aligns with green energy mandates, reducing utility billing overheads and reducing equipment heat profiles.
The landscape of power electronics is changing rapidly due to advancements in new semiconductor materials. As our R&D pipeline expands, we are transitioning our power architectures from traditional Silicon (Si) MOSFETs to Wide Bandgap (WBG) semiconductors: Gallium Nitride (GaN) and Silicon Carbide (SiC).
These advanced compounds allow our systems to operate at higher switching frequencies. The result is a reduction in magnetic component sizes and heat dissipation requirements, enabling our next-generation modular power supplies to achieve up to a 95% efficiency ceiling with a smaller overall footprint. Looking ahead, digital control loops powered by advanced ARM Cortex microcontrollers are replacing analog feedback circuits, enabling real-time telemetry, remote adjustments, and predictive maintenance via Modbus, CAN-bus, or PMBus interfaces.

Our production workflow is optimized to achieve a 99.9% yield rate through strict process control. Quality validation begins during raw component procurement, involving strict testing of all transformers, magnetic cores, capacitors, and active semiconductors. We utilize specialized winding machines and wire-cutting machinery to guarantee uniform tolerances in magnetic coils, which is critical for reducing core losses at high frequencies.
During assembly, advanced automated pick-and-place technology is paired with manual component insertion to ensure correct assembly. Printed circuit boards are processed through wave soldering or automatic soldering machines. Once populated, boards undergo structural and thermal testing. We apply protective silicone potting using canning machines to seal fragile assemblies, securing critical heat paths and protecting components from environmental factors like humidity, dust, and vibration.
Before packing, every power supply undergoes a two-stage testing protocol: computer-aided diagnostic testing followed by load testing under simulated environmental stresses. Highly calibrated DC power supply testers and AC withstand voltage testers evaluate dielectric insulation strength, ensuring safety under high-voltage configurations. Subassemblies undergo aging tests in constant temperature and humidity chambers to eliminate infant mortality components before shipping.
For global procurement managers, system integrators, and engineering firms, sourcing power systems involves key technical and logistical requirements. A key priority is compliance with international safety and electromagnetic standards.
All our modular switching power supplies are CE certified. This certification ensures conformity with Low Voltage Directive (LVD) standards and Electromagnetic Compatibility (EMC) regulations, facilitating smooth imports and compliance approvals. Our power architectures are built with safety margins, including overvoltage protection (OVP), overcurrent protection (OCP), overtemperature protection (OTP), and short-circuit protection (SCP). Our output controls feature quick recovery cycles to protect sensitive loads during transients.
We work to align with lead-time requirements, project milestones, and bulk logistics demands. Located in the manufacturing hub of Shanghai, we utilize reliable global logistics networks to facilitate streamlined ocean, air, and express shipping. Every unit is packed to withstand long-distance shipping, protecting delicate internal electronics from transport damage.
To ensure our equipment arrives in perfect condition, we implement a multi-layered protective packaging protocol. This system is designed to guard against rough handling and moisture during transit:
Sealed in high-density polyethylene moisture barriers to prevent condensation on internal circuits during sea transit.
Protected by custom-molded, high-density polyethylene foam inserts to absorb transport vibrations and physical impacts.
Packaged in heavy-duty cardboard boxes and secured with external wooden frames to prevent crushing under load.
We back our systems with technical support, offering a comprehensive 1-year replacement and repair warranty on all models. In the event of a technical issue, our support team is available to assist with diagnostic support, schematic references, and replacement parts to maintain operational continuity.
