What this product is

What this product is

The Vertiv UF-LTS32-1P is a 1U rackmount Static Transfer Switch (STS) rated at 32A single-phase, offering seamless automatic dual-source AC power transfer in under 5ms for mission-critical IT racks.

What problem it solves

Resolves power grid instability, excessive OPEX energy dissipation, battery degradation, and rack footprint constraints.

Who and where it is for

5G cellular cell sites, core telecom DC plants, AI data centers, transport networks, and critical industrial DC UPS.

Core advantages

  • <5ms Solid-State Transfer: Fast SCR silicon switches eliminate mechanical arcing and contact bounce.
  • Complete Input Isolation: Total electrical isolation between Source A and B prevents cross-fault propagation.
  • Selectable Source Priority: Easy user configuration of primary source preference via front panel controls.
  • 1U Ultra-Compact Subrack: Provides immediate dual-source redundancy to single-cord IT gear within 1U.
