描述

The LCC250-24U-7P is a 250 W fully-enclosed AC-DC power supply from Advanced Energy's Artesyn LCC250 series, featuring convection cooling with a 24 V single output. This unit delivers full useable power at elevated temperatures with an operating temperature range of -40°C to +85°C ambient temperature, making it suitable for demanding outdoor and indoor applications such as outdoor signage, telecom antenna and base station equipment, control consoles, and medical devices. The power supply features IP64 protection against dust and water ingress, 10.4 A maximum output current with ±14.6/-15% adjustment range, and ±2% line/load regulation. Key characteristics include 91% typical efficiency at 230 VAC full load, 1% output ripple (with external capacitors), wide input range of 90–264 VAC, and compliance with multiple safety standards including UL/CSA 62368-1, IEC 60601-1, and CE/TÜV certifications. The absence of cooling fans minimizes dust and noise, making it ideal for noise-sensitive environments while maintaining reliable performance across a wide operating temperature range.
