Liebert Network Power Switch

Vertiv’s Liebert NPS offers swift switching between two independent AC power sources, ensuring uninterrupted operation for critical electronic equipment. The proven power switching technology of Liebert NPS enables dual AC power paths up to the critical load, providing the highest level of AC power system redundancy, availability, and fault tolerance.

  • Designed for High Nines Availability
    Break- Before - Make switching eliminates any possibility of connecting the two independent power sources together, even underĀ fault conditions.
    Diagnostics and transfer tests detect any potential switch failures before the problem becomes critical.

    Rapid Operation
    Network Power Switch transfer time of six milliseconds is invisible to sensitive electronic equipment. (As per IEEE Standard 446 susceptibility curve for IT component)
    Automatic transfer protects the critical load as soon as a problem is detected on the power source by switching to the alternative supply.
    Manual transfer allows power sources to be switched whenever required for scheduled source shutdowns or maintenance.
