Description

This surge protector mainly used light volt power distribution system of lightning surge protection or other transient overvoltage.Products built for high voltage dc power supply overheating over-current protection function, can provide grade C for photovoltaic (pv) power system transient protection.Products using 35 mm DIN rail installation, module can change independently, easy to install and maintain, with remote communication alarm interface (dry contact), surge protector to facilitate remote monitoring.

Technical parameters The maximum continuous operating voltage:Ucpv1300 v Nominal discharge current: In mu s (8/20)20 ka The maximum discharge current: Imax mu s (8/20)40 ka The voltage protection level: - Up (In)4.6 kV or less The Up limit voltage :(5 ka)3.2 kV or less Tolerance Iscpv short circuit current:200 a Terminal connection range:Was 1.5 ~ 25 was (flexible) / 35 was (rigid) The alarm port rated current:250 v / 0.5 A (AC) 0.1 A (DC) of 125 v / 1 A (AC) 0.5 A (DC) Flame retardant grade:UL94 V - 0 Enclosure protection class:IP20

The diffenerce of DC SPD and  AC SPD: Ac surge voltage: 220 v, 380 v to 420 v Keep surge voltage: 24 v, 48 v to 36 v Photovoltaic (pv) keep surge: 500 v, 1000 v, 1300 v, 1500 v Ac surge protector cannot be used in pv junction box used in class Because the alternating current passing zero arc out naturally, direct current zero, however, arc do not naturally go out, cause a fire So the dc must use straight surge protector Photovoltaic pv junction box must use special surge protector
