Key Features

• 650VA capacity with 390W load support: Powers several small devices at once, as long as the combined load stays within 390W.

• Up to 20 minutes of backup: You get time to save work, close programs and shut down properly. Actual runtime depends on the connected load.

• Wide 140-300VAC input range: It works through low and high mains voltage, which helps when supply is unstable.

• Output of 220V ±10%: Delivers steady power to connected devices.

• Simulated sine wave inverter output: Gives dependable backup power for common electronics during an outage.

• 50Hz ±1Hz output in battery mode: Keeps the frequency steady while running on the battery.

Why Choose the Prolink 650VA Offline UPS

Many people buy a UPS only to protect against sudden shutdowns, not to run equipment for hours. This model suits that need. Its quick transfer time protects ongoing work and its 20-minute runtime covers a normal safe shutdown.

The wide input range is useful where voltage swings are common. The 390W load capacity covers most light home and office loads. A Prolink UPS like this one gives you dependable protection without the cost of a larger online system.

Best Use Cases

• Home office: Keep a computer setup running long enough to save work during a cut.

• Small business counters: Protect billing devices from sudden power loss.

• Students and remote workers: Avoid losing assignments or interrupted sessions.
