New series of CRPS power supplies for server and networking applications

Bel Power Solutions has released the PEC Series, a new series of power supplies that provides platinum-level efficiency (up to 94%) for server, storage and networking applications. Based on the CRPS standard, the first models available in the series are the AC versions rated at 550W, 800W, 1300W and 1600W output power. More versions will follow including DC models and Titanium-certified models up to 2400W. All models provide overvoltage, overcurrent, overtemperature, overpower and short circuit protection. Standard or reverse airflow options are also available.

The high-power density of the series helps to enhance the overall system efficiency and improve system reliability. The series power supplies offer a main output of 12VDC to support DC-DC converters in systems utilising distributed power architectures, together with a 12VDC always-on standby output for power management circuitry. Parallel operation with active analog current sharing eradicates the necessity for extra components when multiple units are required for very high current applications. These hot-swappable power supplies support N+1 redundant architecture. All AC-input models in the series provide low total harmonic current distortion (iTHD). Digital control utilising the Power Management Bus protocol and a built-in I2C serial interface enables remote set-up, monitoring and control. Built-in black box recorder application continually monitors the power supply and can be employed to speed up root cause analysis in the possibility of any issues through operation.

The series also supports 180-300VDC input, allowing design engineers to select the same power supply for deployment in HVDC applications. Typical HVDC input sources found to be powering the series include battery backup, DC generators and renewable energy.
