The Marsriva MR-US3K Energy Efficient 3kVA Online UPS is a high-performance power backup solution designed for demanding environments that can’t afford downtime. With a robust 3kVA / 3kW capacity, pure sinewave output, and zero switching time, this double-conversion online UPS keeps your essential systems running smoothly — even during unstable voltage conditions or sudden power failures. Whether you're running a server room, networking equipment, or mission-critical business operations, this UPS delivers consistent, clean, and uninterrupted power with remarkable energy efficiency.
This Marsriva MR-US3K UPS is engineered for serious backup power demands. Built around double-conversion online technology, it ensures seamless power delivery with zero-millisecond switching time from AC to battery mode. That means your connected devices stay on without interruption, making it ideal for sensitive electronics, data centers, or business-critical setups. The UPS has a 3kVA load capacity, capable of handling up to 3kW, making it suitable for medium-sized office environments, industrial systems, or enterprise networking. The pure sinewave output ensures compatibility with all types of electronic equipment, maintaining efficiency and device health over the long term.
At the heart of the Marsriva MR-US3K is a powerful battery system with 6 x 12V 9Ah batteries. These deliver strong runtime and reliability during outages, helping you keep your systems up and running while giving you time to shut down or switch to a generator if needed.
This online UPS supports a wide input voltage range of 110V to 300V, allowing it to handle fluctuating grid power conditions with ease. It auto-adjusts to deliver stable output in the 220V – 240V range, supported by a frequency range of 50Hz/60Hz ± 0.1% in battery mode. Whether you're in a low-voltage area or dealing with unpredictable power, this UPS will keep your equipment protected.
The built-in LCD display offers real-time updates on input/output voltage, battery status, load level, and operational mode. It’s a user-friendly way to monitor the UPS's performance and troubleshoot any issues instantly, reducing guesswork and ensuring control.
The Marsriva MR-US3K uses true double-conversion technology, meaning it converts AC to DC and back to AC for a consistently clean output. This design eliminates noise, voltage spikes, and harmonic distortion, protecting delicate systems like servers, networking gear, and lab equipment. With a power factor of ≥0.99, this UPS maximizes energy efficiency and reduces power wastage — lowering operational costs in the long run.
Unlike line-interactive UPS models that may have milliseconds of delay during power transitions, the Marsriva MR-US3K boasts 0ms switching time between AC and battery mode. This is crucial for sensitive electronics, ensuring continuous power flow without even a flicker of disruption.
Despite its robust capacity, the MR-US3K is compact and easy to integrate into your existing setup. It measures just 345 x 144 x 225mm and weighs 17kg, making it suitable for desktops, server racks, or under-desk installations.
