Its remarkably slim 85.5mm design allows for significant space savings within control cabinets, making it an ideal choice for high-density installations. A standout feature of this series is its wide-range three-phase input (340 to 550VAC), which also supports dual-phase operation under specific derating conditions, providing exceptional flexibility for various electrical grid configurations. The unit's built-in active PFC function ensures compliance with harmonic current regulations while optimizing energy usage across the entire load range. Engineered for maximum durability, the TDR-480-24 boasts an impressive 93% efficiency rating, which minimizes heat dissipation and allows the unit to operate effectively using only free air convection cooling. It is equipped with a sophisticated constant current limiting circuit, making it particularly well-suited for inductive or capacitive loads that often trigger standard power supplies. With full compliance to UL508 and industrial-level immunity (EN61000-6-2), this power supply provides a robust backbone for factory automation, semiconductor fabrication, and electro-mechanical apparatus. The inclusion of comprehensive protection against short circuits and over-temperature, combined with a 3-year manufacturer warranty, guarantees long-term operational stability in mission-critical applications.
