## Long description

Rebel Nanopower 850 is an offline uninterruptible power supply rated at 850VA / 480W for 230 V, 50Hz systems. It delivers short-term battery backup and basic surge protection to maintain power for desktop computers, network devices and peripherals during outages, voltage sags or spikes. The unit is designed for home and small office environments where automatic switching to battery power and a compact footprint are required.
Advantages
The UPS provides instant, automatic transfer to battery power without user intervention, ensuring connected equipment continues operating during brief interruptions. Its rated output power and compact offline topology make it a cost-effective option for protecting single workstations, routers, and external storage devices. The device includes surge protection to reduce the risk of damage from transient overvoltages and supports common 230 V household and office electrical systems.
Suitable for
Desktop PCs and workstations with moderate power draw
Home office setups and small business workstations
Network equipment such as routers, switches and modems
External hard drives, NAS devices with low power requirements
Peripherals like monitors, VoIP phones and point-of-sale terminals
When it may not be suitable
This offline UPS is intended for short-term backup and basic surge protection; it is not designed for long runtime support or for powering high-load equipment. It may not be suitable for servers, professional audio/video installations, or medical and industrial systems that require online double-conversion topology, very low transfer times, or extended battery runtimes.
Key specifications
Topology: Offline (standby) UPS
Apparent power: 850 VA
Rated output power: 480 W
Input/output voltage: 230 V, 50 Hz
Output waveform: stepped approximation to sine wave (typical for offline UPS)
Protection features: surge protection and short-term battery backup
Intended environment: home and small office use
How to use
Connect the UPS input to a grounded 230 V outlet and plug required equipment into the battery-backed outlets to ensure protected devices receive power during interruptions. The unit will normally supply mains power and automatically switch to battery when input voltage falls outside acceptable limits. Periodically check battery status indicators and replace the internal battery according to manufacturer guidance or when runtime becomes noticeably reduced. For best results, avoid overloading the UPS by keeping total connected load within the rated 480 W.
What to consider before purchase
Sum of connected devices’ power draw should not exceed 480 W.
Required runtime on battery for your devices during an outage.
Whether stepped-approximation output waveform is acceptable for sensitive equipment.
Need for additional features such as automatic voltage regulation or extended runtime modules.
Usage recommendations
Place the UPS in a ventilated, dry location away from direct heat and excessive dust. Regularly test the unit under load and follow the manufacturer’s battery maintenance schedule. For critical loads, consider a higher-tier UPS with online topology or increased runtime capacity.
