SCOPE OF APPLICATIONV
SPD2 surge protection device is mainly used for lightning protection of DC power supply systems such as solar power generation system, wind power generation system and automobile power system. Spd1 surge protection device has an indication window to indicate whether the line is struck by lightning,Green means normal, If the red indicator shows that the line is struck by lightning, please replace the protector or module in time. The surge protection device is applicable to AC 50hz/60hz, the working voltage is 275V to 2000V
