Voltmat Power
Engineered with high power density, active thermal management, and ultra-stable variable output parameters, configured specifically to support Dutch industrial safety and integration standards.
The Netherlands is undergoing one of Europe's most ambitious energy and industrial transformations. Historically reliant on natural gas, the country is rapidly shifting toward a highly electrified, low-carbon economy. Driven by national policies such as the Dutch Climate Agreement (Klimaatakkoord) and the European Green Deal, sectors ranging from maritime shipping and horticulture to heavy chemical production are transitioning from fossil fuels to clean electricity. In this context, demand has surged for high-power conversion hardware—specifically industrial-grade 20,000W to 24,000W AC/DC switching power supplies capable of operating reliably under demanding duty cycles.
One of the primary drivers is the rapid deployment of offshore wind farms in the North Sea. The integration of massive gigawatt-scale wind energy requires robust downstream testing infrastructure, hydrogen production facilities (electrolyzers), and high-voltage DC distribution frameworks. Power supplies outputting variable, highly regulated direct current (DC) up to 1000V are key components in hydrogen research, fuel cell testing, and heavy-duty battery cycle simulation. Furthermore, the Netherlands' major industrial hubs—such as the Port of Rotterdam, Amsterdam's tech corridor, and the Brainport Eindhoven high-tech manufacturing region—increasingly require localized, programmable DC power systems to build next-generation hardware platforms.
Grid capacity saturation (netcongestie) is a major challenge for Dutch businesses expanding their manufacturing capabilities. Power solutions operating at 20kW-24kW must offer high power factor correction (PFC > 0.99) and ultra-low Total Harmonic Distortion (THD < 5%) to maintain grid stability. Our high-efficiency systems are designed to comply with strict European grid codes, ensuring smooth approval processes with regional system operators (TenneT, Liander, Enexis, Stedin).
Rotterdam's port authorities are aggressively scaling up shore-to-ship power (Walstroom) and hybridizing local vessel drivetrains. This requires continuous development of DC test benches. A modular 24,000W AC/DC programmable system allows developers to emulate marine battery chemistries, verify safety isolation systems, and test maritime auxiliary equipment under strict maritime safety standards.
Eindhoven serves as the center of Europe's lithography and semiconductor supply chains. Auxiliary processes—such as RF plasma generation, vacuum chamber pump control, and silicon wafer chemical vapor deposition (CVD)—demand power supplies that provide clean, low-ripple, highly predictable DC power, featuring integrated software controls (Modbus, CAN, or Ethernet interfaces) to communicate seamlessly with automated cleanrooms.
How current-gen switching topologies achieve up to 89% conversion efficiency while shrinking the footprint of 24kW systems.
Integrated over-voltage protection (OVP), over-current protection (OCP), over-temperature shutdown, and short-circuit auto-recovery are baseline requirements for global compliance.
By operating at switching frequencies up to 100 kHz, magnetics are downsized, allowing 24kW systems to fit comfortably into standard 19-inch racks.
Equipped with master-slave control units, these high-power modules can be wired in parallel configuration to support multi-megawatt industrial requirements.
Across the globe, developers of high-power equipment are shifting away from traditional linear regulators toward switching topologies. Modern 20,000W to 24,000W AC/DC switching power supplies incorporate digital signal processors (DSPs) to coordinate power conversion stages dynamically. This digital management ensures precise output adjustments—enabling a single power system to output up to 1000V while maintaining ripple levels within margins previously achievable only in lower-power systems. With this architecture, global industrial teams minimize energy loss (heat creation) in their control cabinets, optimizing overall operation expenses (OPEX) and aligning with carbon footprint mitigation directives.
Select configurations featuring 88%-89% efficiency metrics, extensive variable ranges, and rugged builds for high-stability operations.
Detailing how the 20kW-24kW systems serve distinct industrial verticals in the Netherlands.
In places like Groningen and the port areas of Rotterdam, pilot plants are testing small to medium proton exchange membrane (PEM) and alkaline electrolyzers. Efficient electrolysis demands constant direct current. Output ranges up to 1000VDC allow precise control over cell stacks, ensuring clean current input and minimizing chemical side-reactions, thus increasing hydrogen purity and prolonging cell lifespan.
Dutch greenhouse horticulture (e.g., in Westland) leads the world in automation. Advanced artificial LED lighting grids consume significant electricity. Moving from individual decentralized AC/DC LED drivers to a centralized 24kW DC power grid removes heat-producing transformer components from inside the greenhouses, lowers failure points, and simplifies centralized power monitoring.
The Netherlands has one of the highest densities of EV public charging points in Europe. R&D centers validating high-speed chargers rely on 20kW-24kW programmable DC platforms to simulate high-voltage battery modules. These systems mimic load behavior across diverse temperatures and charge states, enabling testing of protection algorithms without requiring physical lithium battery arrays.
Testing high-performance avionics, DC microgrid components, and radar amplifiers requires stable power supplies. Our 20000W-24000W units feature low output ripple and excellent noise insulation. This guarantees that measurements are not corrupted by high-frequency interference (EMI) originating from the power source itself.
How our Shanghai assembly and validation lines guarantee a 99.9% product qualification rate.
Our manufacturing and engineering operations are located in Shanghai, facilitating convenient global transport and logistics. Operating within a professional, state-of-the-art 10,000 square meter factory, our engineering teams have specialized in high-power regulated power supplies for 15 years. Before shipping, each unit undergoes two rounds of thorough testing: a software-automated computer validation sweep and manual technical inspections. This double-layer quality control allows us to achieve a 99.9% product qualification rate before dispatch.
