cope of application CLBZSPD series photovoltaic special DC surge protection device(SPD) used in lightning protection of solar photovoltaic power generation system or other Dc power green means normal,red to represent the fault ,must be replaced and legible;optional remote communication interface,the realization of remote monitoring :high working voltage ,high safety and stability The product can be pluggable modular design ,standard guide installation ,selection of high-quality photovoltaic professional professional lightning protection devices,stable performance ,built-in hot meit ,flow in dual protection circuit,visualization window,normal green,red fault ,large flow capacity,low residual voltage ,fast response(nanosecond),with remote monitoring function,convenient remote monitoring (optional).
This DC surge protection device is protect against DC power line system and other equipment from over voltage and instantaneous over voltage damage.Widely used in photovoltanic combiner box,power inverter,DC distribution cabinet etc.It has advantages of large discharge current,fast respond time,low residual voltage.
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 realiza remote control

1.Do power off when 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 in ductance on lightning discharge.
3.No need special maintenance.when surge protector happens fault,equipment connected to remote sign all will send alarm,then power off and change new SPD mould is fineDimension and wiring Diagram
