產品詳情 Product details

This DC surge protective device is protect againstDC power line system and other equipment from overvoltage and instantaneous overvoltage damage.Widelyused in photovoltaic combiner box, power inverter,DC distribution cabinet etc.Ithas advantages oflargedischarge current, fast respond time,low residaalvoltage.

Features
1.Plug-in type surge protective device
2. Visible window, green means normal, red means fault3.Double protection of fusing and over-current4.Remote signal interface that realize remote control

Technical Parameter

lnstall ation
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 distributedinductance on lightning discharge.
3.No.need .special. maintenance.When surge. pratector. happens fault,equipment .cannected.ta remote.signal will send alarm, then power off and change new spd mould is fine.
