Voltmat Power
Engineered for high stability, low ripple, and rapid transient response. The ideal choice for Spanish R&D centers.
As Spain accelerates its structural transition toward renewable energy, sustainable transportation, and advanced robotics, the requirement for high-reliability, high-power DC test equipment has scaled exponentially. Spain's national decarbonization master plan, the Plan Nacional Integrado de Energía y Clima (PNIEC), sets an ambitious benchmark of achieving an 81% share of renewable energy in the country's electricity generation mix by 2030. In this context, 10000W to 12000W AC/DC switching power supplies are no longer general-purpose utility devices; they have evolved into critical components facilitating large-scale grid simulation, solar PV inverter characterization, and high-voltage energy storage validation across regions like Andalusia, Castile and León, and Aragon.
Simultaneously, Spain's historic automotive centers—ranging from the industrial corridors of Martorell (Barcelona) and Almussafes (Valencia) to Zaragoza and Vigo—are experiencing a massive retooling process to support next-generation Electric Vehicles (EVs). Testing EV battery management systems (BMS), high-power traction inverters, and onboard chargers (OBC) requires highly stable, variable DC voltage sources operating in the 24V to 1000V range. High-power AC/DC supplies capable of delivery up to 12kW serve as the primary simulated battery banks in these stress-testing and hardware-in-the-loop (HIL) systems, enabling local Tier-1 automotive suppliers to replicate real-world road loads and charging profiles safely.
Supporting solar simulation and battery storage testbeds across Spain's burgeoning utility networks with isolated, high-precision DC sources.
Providing high-voltage profiles up to 1000V to simulate traction battery outputs for next-generation electric drivetrains built in Spain.
Powering electrochemical applications, industrial electrolysis, and complex galvanic anodizing baths with ripple-free constant current control.
A technical guide to wide-bandgap semiconductors, digital control topologies, and thermal management architectures.
Modern 10000W-12000W industrial power supplies have shifted away from bulky linear power architectures and older, low-frequency hard-switching configurations. To address the demands of Spanish system integrators for reduced carbon footprints and minimal rack space, our power systems utilize high-frequency switching technology. Below is the technology roadmap that underpins our high-power converters:
Explore these four specialized products designed for robust applications, from aerospace manufacturing to renewable energy simulation.
Our production headquarters is strategically located in Shanghai, a global logistics hub that facilitates efficient maritime and air transport to European distribution centers. With a state-of-the-art 10,000 square meter factory, we specialize in high-power regulated power systems. Over the past 15 years, our facility has integrated advanced automation, digital tracking, and strict quality control protocols to ensure reliable performance for our international partners.
To guarantee that our systems operate reliably in challenging industrial settings, every single unit undergoes a strict multi-tier verification process before dispatch. Our quality assurance protocol includes automated diagnostic testing followed by manual verification by senior power electronics engineers, resulting in an audited 99.9% factory qualification rate.
Additionally, we understand that maritime shipping introduces risk of environmental damage. Therefore, we utilize specialized packing protocols: moisture-barrier vacuum packaging (preventing humidity damage to delicate circuit boards during sea transit), custom-molded shock-absorbing padding (protecting structural frames from vibration damage), double-walled reinforced cardboard cartons, and robust outer wooden crates. This process ensures that your high-power equipment arrives in Spain ready for immediate commissioning.
From initial design concepts to high-temperature aging chambers and optical microscopy, see how our Shanghai plant constructs industrial power solutions.
Ensuring complete alignment with the European Union CE marking directives and Spanish safety standards.
Operating high-voltage power electronics within Spain demands compliance with strict European safety frameworks. Our 10kW to 12kW switching power supplies are designed and certified to meet all major European directives, easing integration into complex industrial lines:
Complies with the Low Voltage Directive, certifying insulation coordinates and structural creepage distances to keep benchtop operators safe from high voltages.
Certified against electromagnetic interference. Integrates robust line filters to suppress both conducted and radiated emissions (EN 55011 / EN 61000 standards).
Built with lead-free solder processes and hazardous-substance-free components, ensuring full compliance with European environmental standards.
To meet local requirements, we offer input voltage configurations adjusted to the Spanish grid standard: three-phase 400V AC (±10% tolerance), 50Hz frequency, with robust internal protection against grid voltage surges and transient events common in industrial zones. We also support digital integration through optional Modbus interfaces, allowing your local engineering team to interface the power supply with standard Siemens S7 or Allen-Bradley PLC architectures.
Select from our complete line of industrial switching power supplies, featuring adjustable voltage ceilings up to 1000V DC.
Expert answers addressing the concerns of Spanish procurement engineers and system integrators.
Our standard systems are engineered for the common European and Spanish industrial three-phase 400V AC line voltage (with a ±10% utility fluctuation tolerance), operating at 50Hz. For specialized laboratories or older infrastructures, we can configure our systems for single-phase 230V AC input, though this may require current de-rating based on power levels. Three-phase Delta or Star configurations are selectable during custom ordering.
Efficiency values are verified using high-bandwidth precision power analyzers during full-load testing. Our Phase-Shifted Full-Bridge (PSFB) topology, combined with low-loss Silicon Carbide (SiC) switches, minimizes loss across the load range (from 20% to 100% load), helping facilities maintain low operating temperatures and meet EU eco-design directives.
Yes. The power supplies feature automatic transition between Constant Voltage (CV) and Constant Current (CC) modes based on the configured load threshold. The digital control loops prevent current spikes during transitions, protecting electroplating tanks, electrolyzers, and battery packs during charge/discharge profiling.
Every 10kW to 12kW system comes equipped with isolated analog control interfaces (0-5V or 0-10V scaling) and RS485 as standard. For automation networks, we can integrate Modbus-RTU, Modbus-TCP, or CAN bus interfaces, allowing connection to PLCs or LabVIEW-based testing setups.
Standard builds typically ship within 3 to 4 weeks from our Shanghai plant. Customized systems (e.g., custom voltages or digital protocols) may take 5 to 7 weeks. To protect the units during sea or air transit, we pack each supply with moisture-barrier vacuum packaging, shock-absorption padding, and robust outer wooden crates, helping to ensure the unit arrives in Spain in optimal condition.
