Discover our foundational high-power switching power supplies, fully customizable from 24V up to 1000V configuration envelopes to match specific mechanical and electrical workloads.
Modern electrical grids, smart factories, and high-performance industrial processes demand more than simple voltage conversion. They require highly efficient, dynamically regulated, and ruggedly constructed custom power modules. As a pioneer in power design based in Shanghai, we provide high-power regulated systems tailored to meet complex, application-specific loads.
For more than 15 years, our engineering team has integrated state-of-the-art power conversion topologies to construct systems ranging up to 24kW and beyond, yielding unprecedented power densities. In critical industrial settings, standard off-the-shelf power modules fail due to thermal limits, lack of protection loops, or insufficient adjustment ranges. This is where custom OEM design comes in: bridging the gap between raw AC grid availability and precision DC loads.
Each unit we construct under goes severe testing procedures. This methodology guarantees stable energy transmission, mitigates high-frequency noise, and provides consistent protection under varying operating conditions.
The industry-wide shift toward Silicon Carbide (SiC) and Gallium Nitride (GaN) technologies represents a major leap forward in high-power converter designs. Conventional silicon power transistors struggle with high switching losses when operated at elevated frequencies. In contrast, SiC-based switches enable our custom modules to handle higher input voltages and operate efficiently at elevated frequencies. This reduces magnetic component footprints, improves thermal management, and yields power densities exceeding 20W/in³.
Modern industrial operations require real-time telemetry and adaptive output adjustment. Our custom power supplies utilize Digital Signal Processors (DSPs) to control switching duty cycles. This design offers distinct advantages over traditional analog control schemes. Users can configure parameters via communication interfaces like RS485, Modbus, or CAN bus. The digital loop allows for precise programming of output profiles, voltage steps, and current limits—critical for battery simulation, electrolyzer power, and laboratory bench use.
High-power switching naturally generates electromagnetic interference (EMI). Our engineering team designs custom EMI filters directly onto the input stages. This ensures compliance with global standards like FCC Part 15 and EN 55011. Thermal management is supported by active fan-cooled tunnels, heavy-duty aluminum heatsinks, and potting compounds. This compound helps transfer heat away from key magnetic parts while providing protection against dust and moisture intrusion in challenging environments.
Operating a professional 10,000-square-meter facility in Shanghai, we blend automatic precision with manual quality control. Each product goes through two stages of computerized and manual testing before shipment, maintaining a 99.9% pass rate. Below is the workflow that supports our engineering capabilities.
Our manufacturing facility features automated wire cutting and winding machines, computerized soldering systems, and precision resin dispensing gear. Environmental stress screening is conducted in-house using environmental testing chambers, optical microscopes, and high-voltage breakdown testers.
We are located in Shanghai, product exports are convenient. The company has a professional production factory of 10000 square meters. I have been specializing in high-power regulated power supplies for 15 years. Excellent after-sales service enterprise in Shanghai. Professional production of stabilized voltage power supply for 15 years. Each product undergoes two rounds of computer and manual testing before leaving the factory, with a product qualification rate of up to 99.9%. The product is transported through moisture-proof packaging (to avoid moisture damage to electronic components), shock absorption (to avoid vibration damage to electronic components during transportation), cardboard boxes (delicate protective cardboard boxes), and wooden frames (reinforced again to ensure transportation safety). High quality and affordable prices, ensuring peace of mind when making purchases.
Procuring custom high-power electronics involves several challenges, including maintaining safety compliance, securing lead times, and managing total cost of ownership. We structure our design and supply chains to address these specific operational demands:
Our custom power modules are developed to simplify the path to UL 62368-1, CE, and RoHS certifications. We source flame-retardant resins, high-temperature wire insulation, and quality magnetics to streamline client-side compliance audits.
With key manufacturing operations based in Shanghai, we maintain access to a robust raw material ecosystem. This proximity helps us secure active components, custom transformers, and CNC chassis parts, keeping lead times steady.
We calculate mean time between failures (MTBF) using conservative thermal models. Our designs utilize durable components, such as Japanese aluminum electrolytic capacitors, to help extend system longevity.
Our custom DC power supplies are deployed globally across demanding application profiles:
Simulating standard battery arrays requires precise voltage controls. Our 15KW-18KW and 24KW DC regulated systems provide stable, low-ripple power, serving as battery chargers and test benches for electric vehicle battery packs.
Industrial plating lines demand continuous, high-current operation under challenging thermal conditions. Our heavy-duty switching regulators supply steady DC current while resisting corrosive airborne compounds via protective conformal coatings.
Powering silicon validation rigs requires clean voltage outputs. Our adjustable single-output power modules operate with minimal voltage drift, protecting sensitive test boards during extended reliability runs.
