Ultra-high-density power supplies extended to 3200W

Advanced Energy Industries, Inc. has extended its range of ultra-high-density front-end power supplies with a 3200W unit in the CPRS 1U form factor. The Artesyn CSU3200ET series addresses next-generation computing applications' high-performance, space-constrained power demands, including AI and ML.

Delivering currents up to 262A, the series performs with efficiencies up to 96% and carries 80PLUS Titanium efficiency certification.

"Generative AI is the fastest adopted technology of all time, as illustrated by ChatGPT's 100 million plus users in just three months. These and other high-performance compute applications require large numbers of power-hungry AI/ML processors, and data centre operators need 80PLUS Titanium efficiency and CPRS form factors to deliver space-efficient solutions capable of powering those processors," said Richard Caubang, senior technical director for enterprise and network products at Advanced Energy. "By extending the power rating of our CSU family to 3200W, we are fulfilling this need with flexible power conversion solutions and advanced options for monitoring and control."

Accepting a universal input voltage range of 180VAC to 264VAC and drawing a maximum input current of 16A, the hot-pluggable power supplies feature active PFC and very low total harmonic current distortion to comply with EN 61000-3-2 limits even at light loads. PMBus® connectivity enables advanced monitoring and control features, while active current sharing facilitates the connection of multiple power supplies in parallel for applications needing higher load current or redundancy. Where system loads do not need the full power of connected power supplies, a 'cold redundancy' capability optimises efficiency.

Models in the series are fully compliant with EMI Class A, IEC/EN/UL 62368-1 and all relevant safety standards.
