ERICSSON直流电源模块PKE4325PI产品介绍
25–40瓦的PKE 4000系列混合式DC / DC电源模块是专门为分散的48/60 VDC配电系统设计的，这些系统具有分布式板载DC / DC转换器，适用于高温和隔离要求的应用。
通过使用可提供高度集成和高效热管理的厚膜技术，并利用基于专有驱动和控制芯片的300 kHz开关频率技术，该高可靠性产品可满足最严格的电信和数据通信要求在恶劣环境下的应用。
输入至输出隔离高达1,500 Vdc，机械坚固性符合IEC 68-2-接近分立元件的要求。这些转换器可以在-45至+ 85°C的环境温度下以自由对流方式工作，并具有全部输出功率，从而使该产品成为室内和室外电信/数据通信应用中最苛刻的温度要求的理想选择。
The 25–40 watts PKE 4000 series hybrid DC/DC power modules are especially designed for decentralized 48/60 VDC power distribution systems with distributed on-board DC/DC converters in applications with high temperature and isolation requirements.
By using a thickfilm technology, which provides a high degree of integration as well as an efficient thermal management and by utilizing a 300 kHz switching frequency technology based on proprietary drive & control chips, the highly reliable products conform to the most stringent telecom and datacom requirements in harsh environment applications.
Input to output isolation is as high as 1,500 Vdc and mechanical ruggedness in conformance to IEC 68-2 – is close to the requirements for discrete components. The converters can operate in free convection with full output power at ambient temperatures from –45 to +85°C, making the products ideal for the most de-manding temperature requirements in both indoor and outdoor tele/datacom applications.
