Artesyn Introduces New 800-Watt CRPS Server Power Supply

By Rob GrayJanuary 23, 2018

Artesyn Embedded Technologies — a global manufacturer of highly reliable power conversion solutions— recently announced the launch of CSU800AP, a new 800-watt server power supply designed for networking and storage infrastructure in hyperscale ecosystems, the cloud, and enterprise IT.   

The CSU800AP power supply is hot-pluggable and compatible with the Artesyn universal PMBus™ graphical user interface. The power supply, supporting control via an integral I2C interface utilizing the industry-standard PMBus communications protocol, adheres to the Intel® Common Redundant Power Supply (CRPS) specifications.

CSU800AP — featuring a remarkably smaller footprint than that of similarly rated power supplies from the previous generation — is housed in a compact 1U high enclosure, measuring just 73.5 x 185.0 mm (2.89 x 7.28 inches). The exceptionally smaller footprint has been achieved by Artesyn using high-density component packaging techniques, and the latest technology in power switching.

Artesyn's CSU800AP power supply generates a main output of 12 VDC for powering downstream DC-DC converters in systems using distributed power architectures. The main DC output can deliver up to 66.7A continuously, with a peak-pulsed capability of up to 93.3A. A 12 VDC standby output rated at 3A can be applied for supervisory circuitry or power management.

Key Features of Artesyn's New 800-Watt CRPS Server Power Supply

Active current sharing helps optimize the cost-effectiveness by eliminating the requirement for any additional components, especially when paralleling a series of power supplies for high-current applications.

CSU800AP, featuring a wide input range of 90VAC to 264VAC, integrates an active power factor correction with improved current harmonics (iTHD) at light loads. More special features of Artesyn's new power supply are as follows:

  • 800 W output power
  • High power and short form factor
  • 1U power supply
  • High density design: 25 W/in3
  • Active Power Factor Correction
  • EN61000-3-2 Harmonic compliance
  • Inrush current control
  • 80 PLUS® Platinum efficiency
  • N+M redundant N+M ≤ 4
  • Hot-pluggable
  • Active current sharing
  • Full digital control
  • PMBus® compliant
  • Accurate input power reporting
  • EN61000-4-5 surge level 2kV/4kV DM/CM
  • Compatible with Artesyn’s Universal PMBus GUI
  • Reverse airflow option

Artesyn's CSU800AP power supply is certified for 80 PLUS® platinum rated efficiency peaking at 94 percent. The high-performance power supply conforms to EN61000-4-11 and Conducted/Radiated EMI Class A standards, complying with safety regulations UL/cUL, CCC, BSMI, KC, TÜV, CE Mark and, UL + CB Report.
