We at QIYU Technologies master in our surge protection devices that can withstand the harshness of nay voltage whatsoever. Our SPD06-LN-15 surge protector has been finely manufactured with thermally protected metal oxide varistors commonly referred to as MOVs. The configuration is fused with a gas discharge tube that grants sharp clamping or cutting down of striking voltages. These gadgets are backed by IEC 61643-11/EN 61643-11 testimonials.

It is highly suitable for use in any sort of luminaire with Class II insulation hence is connected parallel in a circuit. This IP20 rated gizmo offers maximum discharge current of the order 15kA. Although the LED indicator is absent, they are exemplary for outdoor lighting installations.

Their maximum operating voltage lies between 275VAC.Besides, the ambient temperature extends from -40 to 70°C.
