ZYS-S20WLEDII

ZYS-S20WLED/II series surge protector is a transient over-voltage protection device specially used for outdoor LED lighting system. It is mainly composed of thermal protection varistor and gas discharge tube device. It can be installed in LED lamp or perpetual lamp and connected with LED power driver to provide reliable surge protection. It can effectively prolong the service life of lamps and improve the stability of lamps and lanterns.The protection device must be metal oxide varistor type MOV (Metal Oxide Varistor).
