Line-interactive UPS electro base UPS-LI-650 650VA / 390W, LED, 1×7Ah, dimensions 100×280×140 mm

electro base UPS-LI-650 is a line-interactive uninterruptible power supply delivering 650VA / 390W of backup capacity in a compact housing (100×280×140 mm). Designed for small home and office equipment, this UPS provides automatic voltage regulation and battery-backed output to keep essential devices running during short power interruptions and to protect sensitive electronics against undervoltage and surges. An LED status indicator gives a clear visual overview of operating mode and battery condition.

Advantages

The line-interactive topology ensures rapid response to mains fluctuations while maintaining efficient operation. With a single 7Ah sealed lead-acid battery, the unit provides reliable short-term autonomy for routers, modems and compact desktops. The compact footprint and simple LED status indication make installation and day-to-day monitoring straightforward. Built-in voltage regulation reduces the need for frequent battery use by correcting minor voltage deviations automatically.

Suitable for

• Home routers, modems and Wi‑Fi access points
• Small desktop PCs and workstations with low power draw
• Point-of-sale terminals, receipt printers and small retail equipment
• Network switches and small home office setups
• Non-critical peripherals that require short-term power continuity

How to use

Place the UPS on a stable, ventilated surface and connect the input to a grounded AC mains outlet. Attach the required equipment to the battery-backed output sockets so that critical devices receive backup power during outages. Monitor the LED indicator to check mains presence, battery charging and fault states. Before first use, allow the UPS to charge the internal battery for the recommended initial period to ensure full capacity. Periodically test the UPS under load to confirm correct operation and battery condition.

Usage recommendations

For optimal performance, avoid exceeding the rated load and distribute connected devices to prioritize essential equipment. Keep the UPS in a dry, dust-free environment with ambient temperature within the manufacturer’s recommended range. Replace the battery according to its service life or if runtime becomes noticeably reduced; always follow local regulations for battery disposal.
