PEC Series Common Redundant Power Supplies

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

The high power density of the PEC series helps to improve the overall system efficiency and enhance system reliability. Bel Power’s PEC series power supplies provide a main output of 12 V_DC to support DC/DC converters in systems using distributed power architectures, together with a 12 V_DC always-on standby output for power management circuitry. Parallel operation with active analog current sharing eliminates the need for additional components when multiple units are needed for very-high-current applications. These hot-swappable power supplies support N+1 redundant architecture. All AC-input models in the range offer low total harmonic current distortion (iTHD). Digital control using the Power Management Bus protocol and a built-in I²C serial interface facilitates remote set-up, monitoring and control. Built-in black box recorder functionality continually monitors the power supply and can be used to speed up root cause analysis in the event of any issues during operation.
