Engineered for high-efficiency grid compliance, featuring 88-89% efficiency rates and industrial-grade electrical insulation.
Romania has emerged as one of the fastest-growing industrial landscapes in Central and Eastern Europe. Bolstered by massive investments in automotive hubs (such as Renault Dacia in Mioveni and Ford Otosan in Craiova), the region demands highly specialized, reliable, and customizable power conversion systems. To satisfy the rigorous requirements of Industry 4.0 automation, modern test benches, and electric vehicle component testing, local manufacturers require high-precision OEM DC Power Supplies.
Furthermore, Romania’s alignment with European Green Deal goals has initiated a dramatic transition to solar photovoltaic installations in the southern plains and wind farms in the Dobrogea region. These utility-scale renewable systems require high-power DC regulated charging setups capable of managing large battery banks and grid simulation. Standard off-the-shelf units often fail to withstand the local environmental and grid conditions. Thus, customized solutions with active power factor correction (PFC), wide range adjustable voltages, and robust thermal protection are crucial for maintaining operational continuity.
As a leading Shanghai-based exporter with 15 years of technical expertise, we design and manufacture DC power supplies that meet these exact European requirements. Our solutions integrate seamless control interfaces, such as RS485, Modbus, and CAN, ensuring straightforward integration into localized SCADA control rooms and automated assembly lines across Romania.
The worldwide demand for high-efficiency DC power modules is scaling rapidly due to electrification trends. Systems are shifting away from linear topologies towards high-frequency switching technology. By leveraging wide-bandgap materials like Silicon Carbide (SiC) and Gallium Nitride (GaN), modern power supplies reduce dynamic switching losses, allowing efficiencies to consistently exceed 88%. This advancement translates directly to reduced thermal management costs, more compact structural footprints, and a lower total cost of ownership (TCO) for modern industrial buyers.
Based in the industrial hub of Shanghai, our 10,000-square-meter facility utilizes a complete component supply chain, advanced automated winding machinery, and high-speed automatic soldering lines. This local cluster allows us to maintain competitive lead times and raw material cost control while producing robust DC power supplies. Every custom OEM unit undergoes a rigorous two-step validation process, combining computerized automated testing with expert manual inspection to verify insulation resistance and voltage stability.
Long-distance transit from Shanghai to Romanian industrial ports like Constanța requires reliable protective packing. Our components are sealed in moisture-proof vacuum barriers to prevent moisture damage to delicate electronic circuits. We incorporate high-density polyurethane foam blocks to mitigate mechanical shock, then seal the units in multi-wall cardboard cartons. Finally, heavy-duty wooden frames secure the products, ensuring they arrive safely at your site.

Explore our complete range of DC regulated bench power supplies, custom configured for European three-phase voltage standards.
Deploying power supplies within Eastern Europe requires strict adherence to European electrical guidelines. The standard Romanian three-phase industrial grid operates at a nominal voltage of 400V AC at 50Hz. To address voltage instability in remote industrial zones, our switching power supplies are engineered with a wide three-phase AC input tolerance of 380V to 415V AC ±15%. Active Power Factor Correction (PFC) circuitry maintains a power factor of up to 0.99, reducing reactive power losses and complying with EN 61000-3-2 harmonic limits.
Isolation is another critical safety consideration. Our high-voltage models (outputs up to 1000V DC) implement reinforced insulation with a minimum dielectric strength of 3000V AC between input and output, and 1500V AC between input and protective earth (PE). This safety design prevents leakage currents and protects sensitive laboratory testing benches, PLC networks, and manufacturing personnel. Standard cooling options include temperature-controlled, forced-air cooling with variable speed fans, which optimizes thermal performance and reduces acoustic noise on laboratory benches.
Our control loops utilize advanced digital signal processors (DSPs) to achieve rapid transient response times of less than 1ms for load changes from 10% to 90%. Ripple and noise levels are kept to less than 0.1% RMS of the nominal output voltage. This level of stabilization is ideal for high-precision laboratory testing, industrial battery cell formation, and sensitive electro-plating processes.
