required

The 25–40 watts PKE 4000 series hybrid DC/DC

power modules are especially designed for decentra-

lized 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.

深圳市丹凯科技有限公司 聚四氟乙烯（Poly tetra fluoroethylene，简写为PTFE），一般称作“不粘涂层”或“易清洁物料”。这种材料具有抗酸抗碱、抗各种有机溶剂的特点，几乎不溶于所有的溶剂。同时，聚四氟乙烯具有耐高温的特点，它的摩擦系数极低，所以可作润滑作用之余，亦成为了易清洁水管内层的理想涂料。国内外PTFE标准都有哪些？我们一起了解一下.
