ERICSSON直流電源模塊PKE4325PI產品介紹
25–40瓦的PKE 4000系列混合式DC / DC電源模塊是專門為分散的48/60 VDC配電系統(tǒng)設計的，這些系統(tǒng)具有分布式板載DC / DC轉換器，適用于高溫和隔離要求的應用。
通過使用可提供高度集成和高效熱管理的厚膜技術，并利用基于專有驅動和控制芯片的300 kHz開關頻率技術，該高可靠性產品可滿足最嚴格的電信和數(shù)據通信要求在惡劣環(huán)境下的應用。
輸入至輸出隔離高達1,500 Vdc，機械堅固性符合IEC 68-2-接近分立元件的要求。這些轉換器可以在-45至+ 85°C的環(huán)境溫度下以自由對流方式工作，并具有全部輸出功率，從而使該產品成為室內和室外電信/數(shù)據通信應用中最苛刻的溫度要求的理想選擇。
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.
