北京现货供应3U CPCI 电源 CPA250-4530G

CPA250-4530G是一款高可靠性的标准3U的Compact PCI系统供电电源。该系列电源越来越广泛的被应用于通信、铁路，工业、军事、航空航天、电力，服务器等行业。该电源模块超高功率密度，完全符合 PICMGundefinedreg;标准。支持冗余，热插拔功能，在低温和高寒的恶劣天气下能很好的工作。The CPA and CPD Series are highly reliable power supplies for CompactPCIundefinedreg; systems, which are increasingly used in communicati**, industrial, military, aerospace, and other applicati**. 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.Several opti** are available to meet different requirements.
