LITTELFUSE最新推出了瞬变过压保护能力更为强大的新型LED雷击浪涌防护模块系列，适用于户外和商业LED照明灯具。LSP10GIHP系列浪涌保护器（SPD）模块是目前市场上唯一一款结合了低允通浪涌（限制电压或MLV）和低箝位电压等级的串联SPD模块，配有一个内置LED指示灯，可在需要更换时提醒维护人员。低MLV等级有助于防止灯具的LED驱动器发生由浪涌引起的故障，并延长其工作寿命。

该系列采用Littelfuse热保护压敏电阻，有不同工作电压可选（277V或480V）。277V产品可安全地用于120V和240V系统。480V产品可安全地用于347V系统和部分277V系统。即使在压敏电阻寿命终止或持续过压等情况下，内置热断路功能仍能防止灾难性故障和火灾隐患。

该浪涌保护器的应用范围包括道路照明、停车场照明、洗墙照明、交通照明、泛光照明、数字标牌、隧道照明和路灯照明。

“LSP10GIHP系列为当今的照明市场提供最高级别的瞬态浪涌电压保护。”全球营销经理Todd Phillips说，“其低浪涌允通能力保证了SPD模块与其保护的LED驱动器兼容，使灯具设计师可以灵活选择需要的驱动器品牌和功率，而不必担心是否能与SPD模块协作。”

LSP10GIHP系列浪涌保护模块具有以下主要优点：
• 低MLV和低电压保护级别（Up）可减少驱动器故障，降低维护频率。
• 双重绝缘电缆电线，使LSP10 GIHP适合用于IEC/EN 60598-1 II类灯具。
• 内置LED指示灯，可识别SPD模块何时需要更换以持续保护灯具，减少了维护时间。
