Marsriva MR-UF650 650VA Offline UPS

Genuine Product Fast Delivery Easy Returns

Key Features

High Power Capacity: The 650VA / 360W capacity ensures reliable backup for desktops, networking equipment, and small office devices.

Wide Input Compatibility: Accepts both 220V‑240V and 110V‑120V input ranges, making it suitable for Bangladesh’s dual‑voltage environments.

Quiet Operation: Noise level stays below 40dB at 1 meter, providing a silent workspace even during power outages.

Robust Battery Protection: 12V 7Ah battery with alarm every 8 seconds, low‑battery tone, and overload tone keeps users informed of power status.

Comprehensive Protection Suite: Built‑in short‑circuit, overload, overcharge, and overdischarge protection safeguards connected equipment.

Automatic Voltage Regulation (AVR): AVR stabilizes output voltage, preventing damage from fluctuating mains supply.

Fast Transfer Time: Typical transfer time of 2‑6 ms (max 10 ms) ensures seamless switch to battery power without interruption.

Intelligent Charging & Cold Start: Off‑mode charging and cold‑start function keep the battery ready even after long idle periods.

User‑Friendly LED Indicators: Green, yellow, and red LEDs instantly show line, battery, and fault states for quick troubleshooting.

Connectivity Options: Optional USB and RJ45 interfaces allow remote monitoring and integration with management software.

Silent Mode Activation: Effortless silent mode reduces audible alerts during normal operation while maintaining protection.

Durable Build: Compact dimensions (305x94x139 mm) and 4.2 kg weight make it easy to place on desks or shelves.
