HQM AT-UPS650R-RACK 650VA Line-Interactive 1U Rackmount UPS με USB & RS232

For rack environments where every 1U of space counts, the HQM AT-UPS650R-RACK delivers 650VA/390W of line-interactive protection without sacrificing connectivity or control. Unlike basic standby units, it actively corrects voltage fluctuations between 162 and 290VAC, keeping your equipment on simulated sine wave power during brownouts and blackouts. The slim rackmount chassis fits standard 19-inch rails, while dual IEC C13 outlets, USB and RS232 ports, and bundled management software make it a practical choice for small servers, network gear, and point-of-sale systems.

Highlights

• 650VA / 390W line-interactive topology with automatic voltage regulation
• 1U rackmount form factor for space-constrained IT installations
• 2 IEC C13 output sockets for protected equipment
• USB and RS232 communication ports with management software included
• Sealed lead-acid battery with 4-6 hour recharge to 90% capacity
• Audible alarms for battery mode, low battery, overload, and fault

In daily use

The AT-UPS650R-RACK sits quietly in your rack, its fanless operation emitting less than 40dB at one meter. During normal operation, it filters surges and corrects high/low input voltage without switching to battery, extending battery life. When power fails, transfer time of 2-6ms ensures connected devices never notice the switch. The front-panel LED indicators show status at a glance, while the included software allows monitoring and safe shutdown over USB or RS232. With a 12V/7Ah battery, it provides enough runtime to save work and power down gracefully.
