【选型】国产延时熔断保险丝CA425A01.6助力医用呼吸机电源输入过流防护设计,分断电流能力达100A
为避免医用呼吸机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延时熔断保险丝做过流保护设计,选型因素参考如下:
1、额定工作电压:220VAC市电供电,一般选择耐压250Vac保险丝设计;
2、额定工作电流:与负载功率大小相关,一般工作电流1.1A左右,以1.5倍过流防护,建议选择1.6A的保险丝设计;
3、小体积。
针对如上设计需求,推荐选择电安科技玻璃管状保险丝CA425A01.6,尺寸5x20mm,不带引线,最大额定工作电压250Vac,额定工作电流1.6A,分断电流能力达100A,工作温度范围-50℃~125℃,通过UR认证,典型电性参数参考如下图1所示。
图1:电安科技延时熔断保险丝CA425A01.6典型电性参数
推荐理由如下:
1、分断电流能力达100A,具有高安全的切断故障电流能力;
2、小体积设计,尺寸仅5x20mm,满足小型化设计需求;
3、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。
