What this product is

What this product is

The Vertiv ER22020-T is a 4.4kW high-power switch-mode rectifier module delivering 220Vdc/20A for utility substations and critical industrial DC systems. Powered by full DSP digital control and LLC resonant conversion, it provides industry-leading electrical stability across extreme temperatures.

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

  • 4.4kW Power Density: Provides 20A continuous utility charging current, significantly saving panel footprint.
  • LLC Resonant Design: Minimizes switching losses, ensures uniform thermal distribution, and extends MTBF by >40%.
  • Three-Phase Neutral-Free: Eliminates floating neutral burn-out risks, ideal for industrial grid environments.
  • Dual Hardware OVP: Redundant hardware-triggered overvoltage protection isolates the unit instantly to protect battery banks.
