CLBZSPD collection photovoltaic unique DC surge defense device(SPD) used in lightning security of photo voltaic photovoltaic electrical power era system or other Dc electrical power inexperienced means regular,crimson to signify the fault ,must be replaced and legibleoptional remote interaction interface,the realization of remote checking :large operating voltage ,higher basic safety and security
The solution can be pluggable modular design ,common information set up ,assortment of high-top quality photovoltaic skilled specialist lightning protection gadgets,secure functionality ,built-in very hot meit ,circulation in twin defense circuit,visualization window,normal eco-friendly,pink fault ,large movement ability,lower residual voltage ,rapidly response(nanosecond),with remote monitoring perform,handy distant checking (optional).
Solution Introduction
This DC surge defense unit is shield against DC power line technique and other tools from above voltage and instantaneous in excess of voltage damage.Broadly employed in photovoltanic combiner box,energy inverter,DC distribution cabinet and so on.It has advantages of large discharge existing,quick answer time,lower residual voltage.
Characteristics
1.Plug-in type surge protecting device
two.Visible window,environmentally friendly means normal,pink means fault
three.CZPT security of fusing and in excess of-recent
four.Remote sign interface that realiza distant manage

Set up
one.Do electricity off when when join surge security system to program
2.Floor wire must be as brief,straight and thick as feasible to lessen the impact of dispersed in ductance on lightning discharge.
3.No need special maintenance.when surge protector happens fault,products related to remote sign all will send alarm,then electricity off and modify new SPD mould is wonderful
