This DC surge protective device is protect against DC power line system and other equipment from over voltage and instantaneous over voltage damage. Widely used in photovoltaic combiner box, power inverter, DC distribution cabinet etc. It has advantages of large discharge current, fast respond time, low residual voltage.
Features
1. Plug-in type surge protective device
2. Visible window, green means normal, red means fault
3. Double protection of fusing and over-current
4. Remote signal interface that realize remote control

1. Do power off when connect surge protection device to system.
2. Ground wire should be as short, straight and thick as possible to reduce the influence of distributed inductance on lightning discharge.
3. No need special maintenance. When surge protector happens fault, equipment connected to remote signal wil send alarm, then power off and change new spd mould is fine.
Customers can connect signal light or buzzer with this remote signal, when signal light on or buzzer sounds, then power off, change fault SPD module to new one is fine.
