DS98L AC surge protector is used for the 'secondary' protection of the single-phase networks against the surge voltages creating by lightning. DS98 is equipped with in-line safety disconnectin and double output connection. The disconnection will be indicate by the turn on of the red led in the front. Very compact, the DS98L surge protector must be installed close by the equipment to protect, downstream a 'primary' surge protector. DS98L provides both a common and differential mode protection.
