Isolation Voltage: 3000 V AC between Input and Output Dimensions (W x H x D): 85.5 mm x 125.2 mm x 128.5 mm Weight: 1.51 kg Safety & EMC Certificates: UL508, IEC 62368-1, EAC, BS EN/EN61000-6-2 Mounting: DIN Rail TS-35/7.5 or 15 Manufacturer Warranty: 3 Years Information about the MEAN WELL TDR-480-48 The MEAN WELL TDR-480-48 is a professional-grade 480W three-phase DIN rail power supply specifically engineered for high-voltage industrial applications requiring a stable 48V output. Its remarkably slim 85.5mm housing is a key characteristic, designed to maximize cabinet space and allow for higher component density in complex automation environments. A unique strength of this series is its versatile wide-range input (340 to 550VAC), which not only supports standard three-phase systems but also allows for dual-phase operation when derated, providing critical operational flexibility during phase failures or in specialized grid setups. Efficiency and reliability are central to the TDR-480-48, featuring a 92.5% efficiency rating and an active PFC function that ensures compliance with stringent harmonic current regulations. The unit utilizes a constant current limiting circuit for overload protection, which is a significant advantage when powering inductive or capacitive loads that typically cause startup issues for standard supplies. Built with a rugged metal housing and certified to UL508 and EN61000-6-2 industrial immunity levels, this power supply is optimized for semiconductor fabrication, factory automation, and electro-mechanical apparatus. The robust thermal design allows for fanless operation via free air convection, supported by a 3-year manufacturer warranty for long-term peace of mind.
