Uninterruptible Power Supply UPS Alantec AP-BK650 Line-Interactive 0.65 kVA 360 W, USB Type-B, 12 V battery

Alantec AP-BK650 is a Line-Interactive uninterruptible power supply (UPS) providing 0.65 kVA (360 W) output power in a compact black tower. The unit integrates automatic voltage regulation (AVR) and a simulated sine wave output to stabilise and protect connected devices from voltage spikes, sags and interruptions. A built-in 12 V battery with intelligent charging and a USB Type-B port for communication allow controlled shutdowns and event logging; LED indicators and audible alarms report operating status and faults. With dimensions of 297×101×142 mm and a weight of 4.4 kg, this UPS is intended for small servers, network equipment, workstations and other low-power electronic appliances.

Advantages

Line-Interactive topology with AVR provides automatic voltage correction without relying solely on battery power, extending battery life and reducing transfers to battery mode. The built-in 12 V battery features intelligent charging to optimise charge cycles and shorten recharge time. Simulated sine wave output supports many types of computer devices and peripherals, while microprocessor control and self-diagnostic routines continuously monitor unit health. Status LEDs and sound alarms give clear real-time feedback, and the USB Type-B interface enables communication with bundled management software for graceful shutdowns and event history tracking.

Suitable for

• Small office servers and single-server setups
• Network devices: routers, switches, modems
• Workstations, POS systems and cash registers
• Surveillance and alarm equipment, CCTV recorders
• Home office and compact IT racks where space is limited

How to use

Place the UPS on a stable surface near the equipment it will protect and connect the input to a suitable AC mains outlet. Connect critical devices to the UPS output sockets and, if required, connect the USB Type-B port to a computer to enable management software and safe shutdown features. Before first use, allow the unit to charge the internal battery fully according to the manufacturer’s instructions. During mains interruptions the UPS will switch to battery power automatically; when AC mains are restored the unit will automatically restart connected equipment. Use the LED indicators and audible alarms to monitor status and respond to overload or battery replacement warnings.

Usage recommendations

For reliable operation, position the UPS in a ventilated, dust-free environment away from heat sources and moisture. Regularly test the UPS and perform battery health checks according to the maintenance schedule; replace the battery when the unit signals end-of-life. Limit connected load to within the 360 W output rating and avoid powering high inrush devices that may cause overload. Keep the bundled management software updated to ensure accurate event logging and graceful shutdowns during extended outages.
