The Artesyn Embedded Power CSU550AP-3-001 is a 550W front-end bulk power supply designed for distributed power systems. Housed in a 1U high rack-mount enclosure measuring 7.28 x 2.89 inches, it offers a high power density of 17 W/in³ and utilizes the latest power switching technology.
This AC/DC converter provides a main 12V output capable of up to 45A and a standby 12VSB output up to 2.5A. It features a wide input voltage range of 90-264 Vac and boasts 80 PLUS Platinum efficiency, achieving up to 94% efficiency. Key electrical specifications include active power factor correction, EN61000-3-2 harmonic compliance, and a power factor greater than 0.89 at 10% load.
The CSU550AP-3-001 supports N+M redundancy, hot-pluggability, and active current sharing, making it suitable for high-availability systems. It is PMBus compliant, offering full digital control and accurate input power reporting. Safety certifications include UL/cUL, CB Report, CE Mark, CCC, BSMI, KC, and TÜV.
Designed for ITE (Commercial) applications, this converter operates within a temperature range of 0°C to 50°C with derating. Its compact form factor and robust feature set make it ideal for space-constrained, demanding environments.
