Signify unveils 650V driver for DC networks
Signify has unveiled its first 650V DC LED driver aimed at the growing market for direct-current environments in industry. The sensor-ready device is designed to integrate with DC networks in manufacturing, which are increasingly powered by solar installations and battery packs. DC networks eliminate conversion losses between AC and DC, improving overall system efficiency. Additionally, a 650V DC product reduces resistive losses compared to lower-voltage alternatives, making energy transmission more effective.
Many industrial applications, such as electric drives, robotics, and renewable energy systems, operate on DC. They also reduce the need for transformers, rectifiers, power factor correction equipment, and inverters, leading to lower equipment costs and simpler installations. Others in the lighting industry have become alert to the DC trend. Last year, Austrian lighting giant Zumtobel introduced a direct current version of its best-selling Tecton continuous row lighting system. The company says the new Tecton DC can add an extra 4 per cent energy saving.
Proponents of DC systems say that they ensure smoother power delivery, reducing voltage fluctuations and enhancing the reliability of critical equipment. Many industrial sectors are shifting toward DC microgrids, battery storage, and renewable energy integration. A 650V DC product aligns with this transition, supporting seamless integration with solar PV, fuel cells, and fast-charging stations. Additionally, compared to higher-voltage DC systems, 650V provides a balance between transmission efficiency and manageable insulation requirements, making it a practical choice for scalable industrial networks.
Furthermore, the adoption of Power over Ethernet (PoE) networks is growing alongside DC lighting solutions. PoE enables both power and data to be transmitted over a single Ethernet cable, simplifying infrastructure and reducing installation costs. PoE lighting can integrate with building management systems, enhancing control, automation, and energy efficiency. As industries continue their shift towards intelligent, interconnected power networks, the synergy between DC power systems and PoE is expected to play a crucial role in optimising energy usage and operational flexibility.
