感谢以上各位 ：）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.

• 你就不会买个车用的12v200A的再接个12v的小继电器(要开要关都有)？2个加起来也不到10块 -味苦- ♂ (0 bytes) () 09/16/2015 postreply 14:24:39

• 那是我的最后一招。不过哪有那么便宜？我看到的$24左右。 -老生长谈- ♂ (111 bytes) () 09/17/2015 postreply 18:10:32

• 我一开始看了这个，它是个starter relay, 不说continuous 量，不敢冒险 -老生长谈- ♂ (216 bytes) () 09/18/2015 postreply 18:36:18

• 启动电流是正常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，连续电流要175A，不是1A。1A是控制电流 -老生长谈- ♂ (0 bytes) () 09/19/2015 postreply 17:34:53

• 非也。太阳能给电池充电。电池放电时电流很大，我烧过150a的fuse，175a ok -老生长谈- ♂ (0 bytes) () 09/20/2015 postreply 19:41:04
