Liebert SH Series

Alpine Power Systems' experienced technical support & sales team is here to assist your needs:

Liebert SH Series (Hybrid) is the first hybrid product in the industry to offer a true coordinated multi-stage system of suppression. Designed specifically for the needs of the telecommunications industry, it integrates the fast response time of the SAD (Silicon Avalanche Diode) module with the high-energy capability of the standard Liebert Interceptor MOV (Metal Oxide Varistor) modules.

The patent-pending Surge Current Transition Circuit of the Liebert SH continually allows for seamless transition from the primary SAD technology to the secondary MOV array technology suppression system long before component failure becomes a concern. Surge current capacity ranges from 250 kA to 750 kA per phase.
