感謝以上各位 ：）but challenging to find the right current rating

ok, first i need an NC;

also it has to be able to sustain 175a continuous current.

i am unable to find one.  anyone knows where to get it?

 

if i can't get one, i would have to settle with a large 200a NO relay and a small NC relay on the coil line.  it'll be a workaround but i really like to have a single NC directly.  appreciate any leads.

• 你就不會買個車用的12v200A的再接個12v的小繼電器(要開要關都有)？2個加起來也不到10塊 -味苦- ♂ (0 bytes) () 09/16/2015 postreply 14:24:39

• 那是我的最後一招。不過哪有那麽便宜？我看到的$24左右。 -老生長談- ♂ (111 bytes) () 09/17/2015 postreply 18:10:32

• 我一開始看了這個，它是個starter relay, 不說continuous 量，不敢冒險 -老生長談- ♂ (216 bytes) () 09/18/2015 postreply 18:36:18

• 啟動電流是正常3倍，就是除以3也是你要求1A的60倍 -味苦- ♂ (0 bytes) () 09/19/2015 postreply 09:15:44

• 不是啊，連續電流要175A，不是1A。1A是控製電流 -老生長談- ♂ (0 bytes) () 09/19/2015 postreply 17:34:53

• 非也。太陽能給電池充電。電池放電時電流很大，我燒過150a的fuse，175a ok -老生長談- ♂ (0 bytes) () 09/20/2015 postreply 19:41:04
