Meanwell TDR-480-48 DIN Rail Power Supply

The Meanwell TDR-480-48 SMPS belongs to the advanced TDR series, designed for industrial 3-phase applications that require a stable and efficient 48V output. It supports an impressive output power of 480W at a constant 10AMP, with a wide input voltage range of 340–550V AC, making it suitable for global 3-phase supply standards. Engineered using robust AC/DC conversion technology and equipped with built-in power factor correction (PFC), this power supply ensures energy efficiency and voltage stability even under fluctuating input conditions.

The compact design of the TDR-480-48—measuring just 85.5mm wide, 125.2mm high, and 128.5mm deep—allows it to fit easily into crowded control panels. Although the unit has no IP rating, it is optimized for use in dry, enclosed industrial environments. Certified to UL 508ITE and EN/UL/IEC 60950 standards, it provides safety and global compliance for automation projects. The fanless design and lack of dimming technology emphasize its role as a dedicated power backbone for mission-critical equipment.

The Meanwell TDR-480-48 SMPS is widely deployed in PLC panels, robotic cells, motor drive systems, and power distribution cabinets where reliable 48V DC supply is crucial. Its three-phase input support makes it ideal for industrial automation systems that run on high-voltage infrastructure, especially where load balancing and uninterrupted operation are critical. For maintenance engineers, its compact DIN rail design makes installation and servicing fast and safe. Students and junior engineers studying industrial power systems will benefit from understanding how this unit manages constant current delivery with high efficiency in real-world factory settings.

If you are building or upgrading a high-performance automation panel, the Meanwell TDR-480-48 SMPS offers an efficient, safe, and space-saving solution for stable 48V DC power. For long-term reliability and 3-phase compatibility, choose the Meanwell TDR-480-48 SMPS.
