Compact standby UPS for desktop and networking gear

The CyberPower CP550SLG is a 550 VA / 330 W standby UPS that delivers simulated sine-wave output to desktop PCs, workstations and network equipment during outages. Its 120 VAC input range of 96 V to 140 V and 47–63 Hz frequency window suit standard North American mains. Eight NEMA 5-15R outlets provide battery-backed and surge-protected connections for a typical workstation cluster.

Fits a standard 15 A circuit with USB management

The unit plugs into a NEMA 5-15P wall receptacle and presents eight outlets, freeing power strips for non-critical loads. A HID-compliant USB port links to the host computer for automatic shutdown signalling. RJ11 pass-through (one in, two out) protects a phone or modem line without extra adapters. Standby topology switches to battery within milliseconds when voltage leaves the acceptable window.

PowerPanel software enables unattended shutdown

PowerPanel Personal Edition, included via the USB link, monitors battery status and triggers orderly OS shutdown before the 2-minute full-load or 8-minute half-load runtime expires. The replaceable sealed lead-acid battery recharges in about 8 hours. Audible alarms signal on-battery, low-battery and overload conditions. UL 1778, cUL 107.3 and FCC Class B approvals confirm safety compliance.

Questions about this item

How long will the battery last at full 330 W load?

At full load the battery provides approximately 2 minutes of runtime.

Does the unit run silently or generate noticeable fan noise during extended operation?

The standby topology has no active cooling fan listed, so operation is typically quiet with only occasional relay clicks.

What cable or port does the computer need to use the management software?

A standard USB cable connects the HID-compliant USB port to the computer for PowerPanel Personal Edition.
