Overview on the UNOMAT UM-TOP-650-EU UPS: 650VA/360W, 3-step AVR, 2-6ms transfer, intelligent battery.

The UNOMAT UM-TOP-650-EU is a compact 650 VA/360 W uninterruptible power supply designed to safeguard sensitive equipment against power fluctuations. It features a three-step automatic voltage regulation (AVR) system that corrects under- and over-voltage without switching to battery power. Furthermore, its rapid transfer time (typical 2–6 ms) ensures uninterrupted operation during brief outages. Intelligent battery management extends battery life, while wide input tolerance (162–290 Vac) accommodates unstable power grids.

Key Features

• Capacity & Output
  Delivers 650 VA (360 W) with ±10% voltage regulation in battery mode.

• Automatic Voltage Regulation
  Three-step AVR corrects voltage swings from 162 Vac to 290 Vac without switching to battery.

• Fast Transfer Time
  Ensures continuous power with a typical 2–6 ms switchover and 10 ms maximum.

• Battery & Management
  Uses a single 12 V/7 Ah battery; recharges to 90% in 6–8 hours. Auto-shutdown on low battery preserves remaining capacity.

• Comprehensive Protection
  Guards against short circuits, overloads, over- and under-voltage, and deep discharge.

• Intuitive Indicators & Alerts
  LED indicators display mode, load level, and battery status. Audible alarms warn of faults, low battery, and overload.

• Connectivity & Charging
  Includes USB or RS-232 communication port for graceful shutdown under Windows, Linux, Unix, and macOS. Provides a 5 V 1 A/2 A USB port for device charging.

• Robust Design
  Operates in 0–40 °C at up to 90% humidity. Conforms to IEC/EN safety and EMC standards.

Conclusion

In conclusion, the UNOMAT UM-TOP-650-EU UPS combines rapid response, voltage stabilization, and smart battery management in a small footprint. Consequently, it offers reliable power protection for home offices, point-of-sale systems, network devices, and essential electronics. Its full suite of safety features and compatibility with multiple operating systems make it an ideal choice for both personal and professional environments.
