UPS System - 350VA/255W Standby UPS with 6 Outlets

The CyberPower CP350SLG is a compact and cost-effective Standby (Offline) UPS system designed to safeguard home electronics, networking gear, and office peripherals from power disruptions. With a capacity of 350VA / 255W, this unit delivers essential battery backup and surge protection to devices such as modems, routers, VoIP phones, and small desktop setups. This space-saving UPS is ideal for users seeking a reliable power safeguard against blackouts, voltage spikes, and fluctuations×especially in environments with minimal power draw but critical uptime needs.

Features

The CP350SLG features 6 NEMA 5-15R outlets, 3 of which provide both battery backup and surge protection, while the remaining 3 offer surge-only protection for less critical equipment. Its simple LED status indicators and audible alarms alert users to power issues, ensuring quick awareness and response. With built-in EMI/RFI filters, it also protects connected devices from line noise interference that could affect performance. Lightweight, easy to install, and backed by CyberPower's trusted protection, the CP350SLG ensures that even entry-level users have access to dependable, affordable power protection.

Advanced Options

Built for simplicity and reliability, the CyberPower CP350SLG UPS delivers fundamental protection in a streamlined package. It uses Standby UPS topology, which is ideal for lower-powered devices that still need battery backup during outages. This type of system allows the UPS to pass through utility power under normal conditions and switch to battery mode instantly during an interruption. It's a perfect choice for non-critical electronics and small networks that need temporary backup until power is restored or the system is safely shut down. With three battery backup & surge protected outlets, users can connect their key components like networking gear or desktop PCs. The three additional surge-only outlets are perfect for printers, lamps, or other peripherals. The CP350SLG comes with a compact tower form factor that easily fits under a desk or on a shelf. Equipped with LED indicators and audible alarms, it notifies users of low battery, overload, or fault conditions. Backed by CyberPower's 3-year warranty and Connected Equipment Guarantee, this UPS is a smart investment for protecting vital home and small office equipment from power-related damage and downtime.
