Marsriva MR-US3KRT-H 3kVA Online UPS with Pure Sine Wave

The Marsriva MR-US3KRT-H is a 3kVA online UPS that keeps your equipment running through power cuts, voltage swings and unstable supply. Its online design gives a 0ms transfer from AC mode to battery mode, so connected devices see no interruption when the mains fails.

It delivers 3kW of pure sine wave output with a 1.0 output power factor, which suits computers, networking gear and other sensitive electronics. If you are comparing a Marsriva UPS for a home office, small business or server corner, this long backup model is built for that kind of everyday protection.

Key Features

• 3kVA / 3kW capacity: Powers a full workstation setup, networking equipment or several electronics at once, with a 1.0 output power factor for usable real power.

• Online topology: Supplies clean power continuously, so you get 0ms switchover to battery when the mains drops.

• Pure sine wave output: Gives smooth, stable power that is gentler on sensitive devices than modified waveforms.

• Wide input range (110–300VAC): Handles low and high mains voltage without dropping to battery. Operation at 110–176VAC and 280–300VAC is power limited.

• Selectable output (208 / 220 / 230 / 240VAC): Lets you match the output to your equipment.

• Flexible input frequency (50/60Hz ±6Hz default, ±10Hz adjustable): Tolerates unstable supply, including variable sources.

• High efficiency: 95.5% in AC mode at full load (220VAC) and 91.5% in battery mode at full load (96VDC), which helps limit wasted energy and heat.

• Input power factor ≥0.99: Draws power efficiently from the mains.

• IPS display: Lets you check status and settings at a glance.

• Multi-layer protection: Covers short circuit, overload, overcharge and over-discharge for the UPS, battery and connected load.
