Mike Krzyzewski is really a famous coach of Dream Team. She has coached north america men's basketball team for some time, that's clinched numerous medals for his country. Following Londonfl jerseys supplyn Olympic was over, Krzyzewski told The Associated Press that this game will be his final one as national coach, a job he's held for seven years. He had left open the possibility of swomen nfl jerseystaying with the team beyond the London Games, when practice on Saturday said these will be his last Olympics.When asked if he was sure, Krzyzewski didn't hesitate before again saying, "yecheap nfl jerseys wholesales," this will be his last game "If we could win it, then it might be three major championships in a row, i always do not know when that has been done because we haven't usually won http://govoriotkrito.bg/libs/nflcn08.htmthe globe championships," Krzyzewski said. "It becomes an enormous thing for the program." Whatever, he's an awesome coach. His achievement are going to be remembered by the country.cheap nfl jerseys

产品介绍

1 用途
DM-1/3系列电码继电器,在自动控制线路中作为扩大控制范围和提高接触能力之用,应用这种继电器,其供电电源为直流电,其中DM-3系列继电器在释放时可获得不大的延时。

2 动作原理
继电器的动作原理是根据电磁原理而产生的,它具有一个吸引线圈,安装在铁芯上,当铁芯,衔铁之间的气隙中的电磁吸力所产生的力矩超过簧片反作用力矩时,继电器就产生动作,衔铁吸持在铁芯上,此时触点系统处于动作形态,当切断吸引线圈的电源时,由于簧片的反作用力,使衔铁和触点系统恢复至原始位置。

3 技术数据
3.1 继电器的动作电压,返回电压以及释放电压应符合企业标准附录中规格表的规定。
3.2 在长期额定电压下,继电器线圈的功率消耗不大于4W。
3.3 继电器可长期耐受110%的额定电压。
3.4 继电器触点断开能力当电流不大于1A及电压不大于220V,时间常数不大于5H10-3S的具有电感负荷的直流电路,断开功率不大于24W。
3.5 继电器的线圈和所有导电部分对于导电磁体的介质强度应当耐受交流50Hz,1KV电压,历时1min无击穿或闪络现象。
