The LCC1200-28U-9P24 is a 1200 W fully enclosed conduction-cooled AC-DC power supply from Advanced Energy's Artesyn LCC1200 series, designed for mission-critical applications requiring reliable power delivery over extended temperature ranges. This model features a nominal 24 V output with a maximum current rating of 50.0 A, adjustable output voltage capability, and a 5 VDC standby output rated at 1.5 A maximum. The power supply incorporates a thermal baseplate and delivers full 1200 W output power across a wide operating baseplate temperature range of -40°C to +85°C, with typical efficiency of 93.5% at 230 VAC and 100% load. Key technical characteristics include 1.0% output ripple, 2.0% line/load/temperature regulation, input range of 90–264 VAC (1200 W at 180–264 VAC), and active power factor correction with 0.99 typical power factor. The unit operates in both constant voltage (CV) and constant current (CC) modes via selector pin, features PMBus/I²C communication for remote monitoring, and includes AC_OK and DC_OK status signals. With IP20 ingress protection, fanless conduction-cooled design, and compliance with IEC 62368-1, UL/CSA, and CE/UKCA standards, this power supply is ideal for semiconductor equipment, industrial systems, telecommunications, data center computing, and medical applications where thermal management and reliability are critical.
