【应用】国产陶瓷慢熔保险丝CA435A015P助力1800W便携式户外移动电源输入过流防护设计,分断电流能力达10kA
假如不考虑电源转化因素,1800W便携式户外移动电源输入功率也要达到1800W,输入电源电流为1800W/220V≈8.18A,为保证其电源输入因负载短路异常造成燃烧风险,一般需要在电源输入加一颗慢熔断保险丝做过流保护设计,市面上一般选择250Vdc/15A快熔断保险丝,可满足1.8倍过流防护,同时针对高功率电源,需要高分断电流能力的保险丝提升产品安全性;
针对如上的设计需求,推荐选择电安科技(DA Technology)慢熔陶瓷管保险丝CA435A015P,尺寸6X32mm,最大额定工作电压250Vac,额定工作电流15A,分断电流能力高达10kA@250Vac,宽工作温度范围-50℃~125℃,典型电性参数参考如下图1所示。
图1:电安科技(DA Technology)慢熔陶瓷管保险丝CA435A015P典型电性参数
推荐理由如下:
1、宽工作温度范围:-50~125℃,具有出色的高低温环境下过流防护能力;
2、分断电流能力最高可达10kA,具有更高的安全切断电流能力,可提升产品安全性;
3、市面上有成熟的应用,产品性能得到验证。
