Ultra-high-density power supply offers 96% efficiency

Advanced Energy Industries, Inc has extended its family of ultra-high-density front-end power supplies with the addition of the Artesyn CSU2400AT 2400W series. The new series combines the CPRS form factor with an 80PLUS Titanium efficiency certification.

Operating with up to 96% efficiencies, the new power supplies decrease energy consumption and enhance space utilisation in distributed power conversion systems for compute, storage and networking equipment. As well as meeting the challenging demands of new installations, the standard CPRS 1U x 73.5mm form factor enables these power supplies to be swiftly and simply integrated into existing deployments.

“80PLUS Titanium certification is an increasingly common requirement for energy-related products and will soon become mandatory in compliance with European Lot 9 legislation,” said Richard Caubang, Advanced Energy’s senior technical director for enterprise and network products. “The CSU2400AT series addresses these requirements while the CRPS form factor provides a simplified upgrade path to higher efficiency, more space-efficient solutions in existing installations.”

Accepting input voltages of 180VAC to 264VAC and 180VDC to 336VDC, the hot-pluggable power supplies offer active PFC, very low total harmonic current distortion to comply with EN 61000-3-2 limits even at light loads and are PMBus-compliant. Each power supply provides a nominal output voltage of 12.2V, whilst active current sharing enables the connection of multiple power supplies in parallel for applications demanding higher load current or redundancy. A ‘cold redundancy’ capability optimises efficiency in cases where system loads do not need the full power of connected power supplies.

The series complies with EMI Class A, IEC 60950 and IEC/EN/UL 62368 standards and all relevant safety standards.
