Voltmat Power
Engineered with high efficiency, active power factor correction, and rugged build qualities to support demanding industrial workloads.
Established as a premier technological hub in Shanghai, our corporation has dedicated over 15 years to the research, development, and high-volume manufacture of high-power regulated DC power supplies. With a state-of-the-art production factory spanning 10,000 square meters, we act as both a direct OEM manufacturing facility and an active exporter to global industrial hubs.
Our location in Shanghai grants us access to some of the world's most advanced logistics corridors, allowing us to export heavy industrial equipment efficiently via ocean and air freight. Over a decade and a half, we have built a reputation on high quality and affordable prices, ensuring global procurement managers achieve maximum ROI without compromising on operational reliability.
How system integrators and procurement departments assess stability, performance metrics, and safety under continuous load conditions.
High-current rectifiers generate electromagnetic interference (EMI) and output ripple. Our designs limit Peak-to-Peak Ripple ($V_{pp}$) to less than 0.5% of the rated output voltage, preventing signal distortion in downstream electronics.
When an industrial process jumps from 10% load to 90% load, our digital feed-forward loop design ensures the output voltage recovers to nominal values within < 1 millisecond, preventing undervoltage shutdowns.
Operating high-wattage power grids requires minimizing reactive power penalty costs. Our units have a power factor exceeding 0.99 at full load, conforming to worldwide grid regulations and lowering electrical currents inside supply lines.
| Parameter Class | Standard Output Ranges | Industrial Target Application | OEM Customization Range |
|---|---|---|---|
| High-Power Rectifiers | 10kW - 24kW+ | EV battery test, electroplating, chemical electrolysis | Voltage 12V to 1000V / Current up to 3000A |
| Medium-Power Regulators | 1.8kW - 7kW | Laboratory test benches, heavy-duty motor burn-in | Variable voltage output with custom digital interfaces |
| Compact DC Supplies | 400W - 1000W | ATE automation racks, communications equipment | Single phase wide-range inputs with rackmount chassis |
Cross-sector deployment of power systems in modern infrastructure, testing, and production facilities.
Electric vehicles (EVs) require rigorous battery simulation and motor drive testing. Our custom high-voltage, high-current DC power units supply continuous, clean energy to mimic vehicle battery packs. These devices allow developers to test bidirectional inverters, battery management systems (BMS), and fast-charging points under controlled, repeatable parameters.
By leveraging high efficiency values of 88-89% and wide voltage capability (up to 1000V output options), we reduce thermal strain on customer test bays, improving safety and saving on long-term electricity overheads.
Industrial surface deposition operations depend on uninterrupted, ripple-free current. A minor pulse deviation in voltage can lead to micro-fractures, uneven coating thickness, or mechanical vulnerabilities in aerospace and automotive finishes.
Our power supplies, such as the 600V-20000W High Precision DC Adjustable Switching Power Supply, are custom-tailored with high-speed analog and digital controllers. This enables continuous current regulation down to 0.1A increments, which stabilizes the electrochemical deposition process even in harsh electroplating environments.
Operating from a 10,000㎡ plant in Shanghai, we optimize modern manufacturing methods to secure consistent supply chains and competitive cost points.
Our Shanghai facility is equipped with semi-automated assembly, automatic soldering machinery, laser engraving, and climate-controlled testing areas. By centralizing core metalwork, winding, assembly, and quality validation processes, we minimize dependency on external component vendors.
This vertical integration guarantees two major advantages for global OEM customers:
Before packing, each product undergoes two rounds of testing (automated computer testing and manual engineer verification). First, we use dedicated DC power supply testers to check accuracy, efficiency, and stability parameters. Second, our quality control engineers verify insulation integrity under simulated load conditions. Through this process, we maintain a 99.9% product qualification rate.

How next-generation power topologies and digital management systems shape our engineering plans.
Transitioning from silicon components to Silicon Carbide (SiC) and Gallium Nitride (GaN) structures allows us to achieve higher power density, lower switching losses, and stable operation up to 150°C, increasing overall unit efficiency above 93%.
Integrating advanced Digital Signal Processors (DSP) supports real-time firmware reconfiguration. This enables modifiable software parameters, remote diagnostic logs, and dynamic protection curves tailored to specific operational needs.
Developing onboard predictive analytics models to monitor capacitor degradation and temperature rises, providing maintenance warnings via Modbus, CAN bus, or Ethernet connection before a hardware fault occurs.
Preparing power equipment for safe transport and seamless installation into local electrical grids worldwide.
Exporting high-current DC power units requires careful attention to electrical grids and transport safety. Each territory has distinct mains input requirements (such as 110V/220V single-phase or 380V/480V three-phase systems). Our engineering team configures inner wiring and transformer topologies to match the destination country's voltage profile.
To withstand long-distance shipping hazards, we utilize a multi-layered packaging protocol:
Our designs meet CE, RoHS, and local electromagnetic compatibility (EMC) regulations, simplifying authorization steps for importing companies. We provide full schematic data and testing certificates to help clients obtain building certifications and regulatory approvals easily.
Technical answers regarding product capabilities, customization options, and engineering practices.
We customize output voltage ranges (from 12V to 1000V+), output current levels (up to 3000A), analog interfaces (0-5V, 0-10V, 4-20mA), digital communication configurations (RS485, CAN bus, Modbus, Ethernet), custom chassis enclosures (rackmount or standalone cabinet units), and environmental protection coatings (tropicalization) for humid conditions.
Every power supply undergoes dual-stage testing before leaving our Shanghai factory. First, automated testing validates electrical performance parameters under standard loads. Second, our quality control team performs manual inspections, insulation resistance checks, and extended burn-in testing to verify system stability under maximum heat and load profiles.
Our power supplies include multiple built-in safety systems, including Over-Voltage Protection (OVP), Over-Current Protection (OCP), Over-Temperature Protection (OTP), and Short-Circuit Protection (SCP). These safeguards prevent damage to the power unit and downstream equipment in the event of an electrical fault.
Yes, most of our models support parallel and series configurations. Parallel setups increase the current output, while series connections provide higher voltages. Integrated current-sharing diodes and control connections ensure even distribution among linked units.
We wrap each unit in moisture-proof plastic film to seal against humidity during sea shipping. The equipment is then housed in form-fitted, shock-absorbing padding within heavy-duty cardboard boxes, which are secured in reinforced wooden frames to protect against vibrations and impacts during transit.
