Product information

Description

The FSP ST 850 is a line-interactive uninterruptible power supply designed to provide short-term backup power and surge protection for desktop PCs, networking devices and peripheral equipment. With a rated output of 0.85 kVA (510 W), four Type F AC outlets and an internal 12 V 9 Ah battery, this tower UPS supplies conditioned power during brief outages and voltage fluctuations. A USB Type-B communication port enables connection to a host system for monitoring, while active cooling helps maintain stable operation. Recharge time for the internal battery is approximately 6.8 hours.

Advantages

The UPS offers automatic voltage regulation through its line-interactive design, protecting connected equipment from sags and spikes without switching to battery for minor variations. Four grounded AC outlets support multiple devices simultaneously, and the compact tower form factor fits typical office or home environments. Built-in active cooling reduces thermal stress during extended use, and the USB Type-B port allows for software-based status monitoring and safe shutdown when integrated with compatible systems.

Suitable for

Desktop computers and workstations
Home and small office network equipment (routers, switches, modems)
External storage devices and printers requiring short backup
Point-of-sale terminals and small business systems

How to use

Place the UPS on a stable, flat surface with adequate ventilation and connect critical devices to the AC outlets. Plug the UPS into a grounded mains socket and allow the internal battery to charge fully before relying on battery backup. Connect the USB Type-B port to a computer if monitoring or automated shutdown features are required; install any manufacturer-provided software to configure notifications and safe-shutdown thresholds. Regularly test the UPS by simulating a power interruption to verify that connected equipment receives backup power and that monitoring functions operate as expected.

Usage recommendations

For reliable short-term backup, avoid connecting high inrush or continuous high-load devices that exceed the 510 W output rating. Keep the UPS in a cool, dust-free environment and allow at least several hours for the battery to recharge after a full discharge. Follow the manufacturer's guidelines for periodic battery replacement to ensure continued backup capacity.
