  • 120V input suits standard North American power
  • Automatic voltage regulation protects connected equipment
  • Integrated SNMP card enables remote monitoring

Lithium-Ion Rack UPS

The Vertiv Liebert PSI5 is a lithium-ion uninterruptible power supply rated at 1920VA and 1920W for 120V environments. It fits standard rack installations and includes an SNMP card for network management. The unit suits IT rooms and edge deployments that need reliable battery backup with a compact footprint.

Runtime and load constraints

At full 1920W load the battery provides roughly five minutes of runtime, which covers brief outages and allows orderly shutdown. Longer interruptions exceed the internal capacity, so extended backup requires external battery modules or a generator. Automatic voltage regulation handles sags and swells without draining the battery.

Capacity headroom

The 1920VA rating matches the watt rating, giving a unity power factor that simplifies load planning for modern servers. It comfortably protects a fully loaded 1U or 2U rack server with networking gear. Workloads that exceed 1920W or need hours of autonomy fall outside this unit's design envelope.
