Eaton AV550SC – 550 VA Standby UPS with Structured Wiring Protection

Overview :

The Eaton AV550SC is a standby uninterruptible power supply (UPS) designed to provide battery backup, surge suppression, and noise filtering for structured AV, network, and cabling equipment. It is typically deployed by IT support teams, AV integrators, and network administrators to protect critical connectivity hardware — such as modems, routers, RF amplifiers, and network interfaces — in structured wiring enclosures and home‑office setups where uptime matters.

Technically, the unit delivers 550 VA / 300 W capacity and integrates regulated surge protection with EMI/RFI line noise filtering to stabilize power under utility disturbances. A front‑panel auto‑restart and recycle/reset button provides recovery sequencing for freeze‑prone devices. The UPS includes four NEMA 5‑15R outlets, one of which has a delayed startup to sequence router power on return of mains. It also features telephone/DSL and coax surge suppression to protect communications lines.

The AV550SC is suited for edge and small infrastructure deployments such as structured wiring closets, small office wiring panels, home network cabinets, and surveillance or point‑of‑sale installations. Its compact vertical tower form factor fits into enclosures without dedicated mounting brackets.

Integration requires only a standard 120 V AC mains feed, and the UPS accepts an IEC C14 input via the included detachable cord. It offers regulated 12 V DC output for powering low‑voltage devices, enhancing flexibility in mixed power environments. The UPS supports standard safety and EMC compliance, making it compatible with broader North American AC infrastructures.

In a practical deployment, the AV550SC maintains power to a broadband modem and router during short outages while filtering spikes and noise that can disrupt connectivity. The delay‑on outlet ensures peripherals like routers start in the correct sequence after an outage.

This device should not be used where true online double‑conversion protection or higher capacity support (>550 VA) is required such as with large servers, SAN storage, or mission‑critical racks. It also lacks network management interfaces for remote UPS monitoring.
