🔋 General Overview

• Model: ZIMA 650V (also listed simply as 650VA)

• Type: Line-interactive UPS (switches to battery during power failure)

• Capacity: 650VA / ~360 W output power — suitable for basic desktops, routers, modems, and similar devices.

⚡ Input (Mains Power)

• Nominal Voltage: ~220 VAC

• Input Voltage Range: ~145 V to 280 V AC — tolerates wide mains fluctuations.

• Frequency: 50 Hz.

🔌 Output (Battery Mode)

• Voltage (Battery Mode): ±10 % of rated output (around 220 V).

• Frequency (Battery Mode): ~50 Hz ±1 Hz.

• Waveform: Modified/simulated sine wave when on battery (not pure sine).

• Transfer Time: Typically < 6 ms switching from mains to battery.

⚠️ Modified sine wave is fine for basic electronics and PCs, but not ideal for sensitive audio equipment or some medical devices.

🔋 Battery Information

• Battery Type: Sealed lead-acid (12 V, ~7.2 Ah to 8.2 Ah — depending on the exact unit/stock).

• Quantity: Usually 1 battery inside.

• Charging: ~6 hours to reach ~90 % capacity on most listings.

• Backup Time: Short — typically a few minutes (e.g., enough to save work and shut down safely).

💡 Indicators & Alarms

• LEDs:

  • Green for AC mains mode

  • Red flashing for battery mode

• Audible Alarms:

  • Beeps when battery is low

  • Beeps for overload

  • Continuous beeping for faults.

🛡️ Protection Features

• Overload protection

• Deep discharge protection (protects battery)

• Over-charge protection

• Helps protect connected devices from spikes and sudden outages.

🌡️ Environment & Noise

• Operating Temp: ~0 °C to 40 °C

• Relative Humidity: 0–90 % (non-condensing)

• Noise: < ~40 dB at 1 m.

📏 Physical Specs

• Dimensions: ~410 × 300 × 435 mm (some sellers show smaller sizes depending on version)

• Weight: ~5 kg.

🧠 Usage & Notes

✅ Great for:

• Desktop computers with moderate load (keep total wattage <360 W)

• Routers, modems, CCTV systems

• Short interruptions where you need time to save work and shutdown safely

❌ Not ideal for:

• High-power devices (e.g., large gaming PCs with >400 W draw)

• Long backup durations

• Sensitive electronics requiring pure sine wave output
