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

          DZ-700電磁式中間繼電器,是上海人民電氣有限公司 http://www.daptopoultryclub.com 為您提供的關于DZ-700電磁式中間繼電器型號,DZ-700電磁式中間繼電器價格,有關DZ-700...

        產品介紹

        1   用途
             DZ–700電磁式中間繼電器(以下簡稱繼電器)作為一種輔助繼電器用于直流操作的各種保護和自動控制裝置中,以增加觸點的數量及容量。

        2 結構與工作原理
              繼電器采用JK-4殼體,其外形尺寸、背后端子及安裝開孔圖見附錄2。背后端子接線圖見圖1。繼電器是在DM1電碼繼電器的基礎上,增加底座和外殼而成。當在繼電器線圈上加電壓,且等于或大于動作電壓時,銜鐵就被電磁吸力吸靠在鐵心上,而接觸片在銜鐵頂板的推動下,觸點接通、斷開或轉換被控制電路,當繼電器線圈被斷電或電壓降低到小于返回電壓時,銜鐵在接觸片的作用下返回到原來位置。           

        主要技術要求
             1.繼電器的額定電壓及線圈電阻值見表1。
