【应用】TT Electronics浪涌电流限制电阻器可用于电子镇流器,环境温度范围-55℃~155℃
镇流器在初始启动期间的浪涌电流比其正常工作电流大几倍,而且一般而言,电子镇流器的浪涌电流高于电磁镇流器或混合镇流器。
浪涌电流限制电阻器用于承受浪涌电流,但在发生故障时可以安全熔断,例如,因为电容短路导致电源短路。TT Electronics旗下典型器件是WP-S、ULW和EMC系列。
WP-S系列:
25℃下,额定功率在1W~5W之间(从WP1S到WP5S逐渐增加),过载功率在5W~25W之间(从WP1S到WP5S逐渐增加),环境温度范围为-55℃~155℃。除此之外,WP-S系列还提供防火保护。
ULW系列:
图2 ULW系列
ULW系列为UL1412认证的易熔电阻,为故障安全120/240Vrms电源熔断器,具备抗浪涌性能。25℃下,额定功率在2W~5W之间(从ULW2到ULW5逐渐增加),25℃下5s过载功率在10W~25W之间(从ULW2到ULW5逐渐增加),环境温度范围为-55℃~155℃。
EMC系列:
图3 EMC系列
EMC系列经过UL1412认证,为故障安全240V电源熔断器,具备良好的脉冲处理能力,拥有额定功率下的小尺寸封装。EMC2在70℃下的额定功率为2W,绝缘电压为500V,环境温度范围为-55℃~155℃。除此之外,EMC系列提供UL94-V0认证的防火保护。
