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

一、用途

 

 

    DZS-12CE/S型直流回路监视继电器(以下简称继电器)用于监视直流电源及整个跳闸回路。当直流电源消失、跳闸线圈及引线发生故障,继电器经0.3s延时返回并通过它的触点发出报警信号。

 

 

二、工作原理

 

 

         

 

 

    当跳闸回路完好时继电器在直流额定电压下处于动作状态,发光二极管燃亮。一旦跳闸回路断路或直流电源消失,继电器则经过0.3s延时后返回,指示灯熄灭。

 

 

三、技术要求

 

 

    1、额定值:直流额定电压为48V、110V、220V。

 

 

    2、继电器触点形式为202(两动合两转换)。

 

 

    3、继电器的动作电压为额定电压的30%~70%。

 

 

    4、继电器的返回电压不小于3%额定值.

 

 

    5、返回时间不小于0.3s。

 

 

    6、功率消耗:继电器在输入激励量为额定电压时功率消耗不大于5W.

 

 

    7、触点断开容量:DC  250V/1A/50W ;AC  250V/3A/250VA

 

 

    8、绝缘电阻不小于300MΩ。

 

 

    9、介质强度:2kV/50Hz/1min

 

 

    10、机械寿命为2.5×104次。

 

 

四、外形结构及安装开孔尺寸

 

 

    本继电器采用JCK-10A/5壳体,其外形及安装开孔尺寸
