Description
Standby Power for Desktop and Network Equipment
The Mercury Maverick 850 is an offline UPS that delivers 850VA/510W of standby power through two universal sockets. It ships with a 12V/9AH sealed lead-acid battery and a UK power cord for immediate deployment.
Input accepts 220VAC or 240VAC nominal within a 140-300VAC window at 50/60Hz. A line-interactive topology adds boost and buck AVR, so the output stays within ±10% on battery and tracks the input on mains.
Transfer time ranges from 2 to 6 milliseconds, with a 10 ms ceiling. The simulated sine-wave output feeds routers, switches, POS terminals and desktop PCs. A built-in charger restores the 9AH block to 90% capacity in about six hours.
The steel chassis measures 283 x 101 x 140 mm and weighs 4.2 to 4.5 kg. Operating temperature spans 0 to 40°C at 0 to 90% relative humidity. Audible alarms distinguish battery mode, low battery, overload and fault states.
Key Features
850VA/510W Power Rating
The 850VA apparent power and 510W active power envelope covers SOHO routers, switches, and desktop workstations.Line-Interactive AVR Topology
Boost and buck automatic voltage regulation corrects sags and swells without draining the battery.12V/9AH Sealed Lead-Acid Battery
A single 9AH block provides typical backup of 10 to 25 minutes depending on connected load.Dual Universal Output Sockets
Two universal sockets accept UK, EU, and US plug types without adapters.Audible Alarm and LED Status
- Battery mode sounds every 10 seconds, low battery every second, overload every half second.
- Green LED indicates line mode, yellow flashing indicates battery mode, red indicates fault.
Cold Start and Auto Restart
The UPS starts on battery without mains power and restarts automatically when AC returns.Compact Chassis
The 283 x 101 x 140 mm steel enclosure weighs 4.2 to 4.5 kg and fits under a desk or on a shelf.Generator Compatibility
The input stage tolerates the wider frequency and voltage swings produced by small standby generators.

Why Choose the Maverick 850
The line-interactive AVR stage corrects brownouts and overvoltage without cycling the battery, which extends block life in unstable grid areas.
Dual universal sockets remove the need for plug adapters when racking mixed UK and EU equipment.
A 510W active rating covers an entry-level desktop and a 24-port switch on a single unit.
The 2-6 ms transfer window keeps switched-mode power supplies running through short outages.
Cold-start capability lets technicians commission the UPS before mains power reaches the site.
The steel enclosure and sealed battery block suit dusty floor cabinets and server cupboards.
