Liebert TYPE SS Transient Voltage Surge Suppression
MOV/SAD Current Sharing – Type 1 Model
The Liebert Answer:
The Liebert TYPE SS Type I Model
offers a true, coordinated multi-stage
system of suppression. It integrates
the fast response time of the silicon
avalanche diode (SAD) with the high-
energy capability of the metal oxide
varistor (MOV) for increased reliability
and performance. This unique circuitry
does not sacrifice the sensitive SAD
module when subjected to a
damaging high-energy transient event.
