The INV‑4820ESA belongs to the Matrix 2000 Series by Eaton. It is a standalone inverter designed to provide a reliable AC power supply in environments where DC sources (‑48 V telecom racks, battery systems) are used. The unit accepts a nominal 48 VDC input (operating range 40‑60 VDC) and offers selectable AC output voltages between 208‑240 VAC at 50/60 Hz. It supports a pure sine wave output with power factor 1.0, and efficiency greater than 91% at rated load. Overload protection is built‑in (2× nominal current for 5 seconds, etc.). The inverter is suitable for rack‑mount deployment (1U height / 19” rack) and comes with fan‑cooling, LCD/LED status display, and integrated static transfer switch (STS) functionality for high availability. Some parameters such as full dimensions and country of manufacture require confirmation.
