AC Mains Protection

电源的电路保护 - 交流电源

Solutions:

Protection Application:: 直接连接到交流电源（120至250VACRM）的产品将暴露于比DC输入中更严重的激增瞬变（闪电，负载开关等）和短路/超负荷条件。因此，保护设备需要更加强大。
解决方案描述：: As shown at the left (top), a cartridge or leaded fuse (Pico, 5x20mm, 2AG, 3AG, TE5/TR5) can be used for short circuit and overload current conditions. For surge protection, an MOV should be used. The MOV should be selected based on the expected severity (energy, voltage and peak pulse current) of the transient surge. The specific family (C-III, UltraMOV or LA) can be determined after the surge severity is understood.
