## Long description

The Fortron ST 850 line-interactive uninterruptible power supply provides reliable backup power and voltage regulation for sensitive electronic devices. With a capacity of 0.85 kVA and an output power of 510 W, this black tower-format UPS features four Schuko AC outlets and active cooling to protect your equipment against power surges, fluctuations, and outages. Equipped with a 12V 9Ah battery and automatic voltage regulation supporting an input voltage range from 81 V to 270 V, it ensures continuous operation for home and office electronics.
Advantages
This uninterruptible power supply utilizes line-interactive topology along with automatic voltage regulation to stabilize incoming electrical fluctuations without switching constantly to battery power, which helps extend internal battery lifespan. The inclusion of four Schuko outlets allows multiple peripherals to be connected directly. Active cooling prevents overheating during prolonged power corrections, and the intelligent battery management system automatically recharges the battery once normal mains power is restored, ensuring the unit is always ready for the next disturbance.

Home desktop computers and associated peripheral monitors
Small office networking equipment, routers, and switches
Point of sale terminals and cash registers
Entertainment systems and digital storage drives
When it may not be suitable
This unit is not designed to support heavy-duty industrial machinery, large household appliances, or high-draw server racks that exceed its 510 W output limit. It is also unsuitable for sensitive medical life-support systems requiring specialized power redundancy.
