CPD250-4530G是一款标准的直流48VDC输入的3U8HP的CPCI电源，符合PICMG 2.11标准，是一款专门为通讯CompactPCI系统供电设计的。这款直流CPCI电源支持冗余热插拔。该宽温电源模块支持-40度--55度及高海拔情况下温度可靠工作。

The CPA and CPD Series are highly reliable power supplies for CompactPCIundefinedreg; systems, which are increasingly used in communications, industrial, military, aerospace, and other applications. These power supplies offer high power density in plug-in modules that meet the requirements of the PICMGundefinedreg; power interface specification for CompactPCIundefinedreg; systems. The converters use the patented EDGETM technology and provide important advantages such as flexible output power, extremely high efficiency, excellent reliability, full input-tooutput isolation, negligible inrush current, hot-swap capability, soft start, and overtemperature protection.
The input is protected by a transient suppressor (varistor) against surges and transients occurring on the source lines and cover an operating input voltage range from either 90 to 264 VAC or 36 to 75 VDC.
The outputs are protected against continuous overload, open-circuit, and short-circuit. Full n+1 redundant operating mode is made possible by integrated ORing FETs or ORing diodes. When several converters are connected in parallel, a single-wire connection between converters ensures proper current sharing.
The converters are designed with two or three separate forward converters with fixed switching frequency and synchronous rectifiers at their output.
LEDs on the front panel and various warning signals display the status of the converter. The aluminum case acts as a heat sink and as an RFI shield. It is designed for vertical insertion into 19" rack systems, but it can also be mounted in any other position, as long as the necessary airflow is ensured. The connector is a 47 pin type from Positronic or similar.
