FSP ST 1500 Tower line-interactive UPS 1500VA 900W 8x IEC C13 -pistorasialla, USB & RS-232, RJ45-ylijännitesuojaus

The FSP ST 1500 stands apart from basic standby units by using line-interactive topology with automatic voltage regulation (AVR). Instead of switching to battery for every minor fluctuation, it corrects brownouts and overvoltages on the fly—extending battery life and keeping connected equipment running smoothly. With 1500 VA / 900 W capacity and eight IEC C13 outlets, it is a solid choice for workstations, small servers, network devices, and point-of-sale systems.

Highlights

• Line-interactive UPS with AVR for stable output voltage
• 1500 VA / 900 W capacity with simulated sine wave on battery
• 8x IEC C13 battery backup and surge protected outlets
• USB and RS-232 communication ports for monitoring and management
• RJ45 network surge protection for phone/network lines
• Tower form factor with audible alarms and LED indicators

In daily use

The FSP ST 1500 protects against power outages, sags, surges, and spikes. Its AVR technology corrects minor voltage variations without draining the battery, ensuring longer runtime when a real outage occurs. The front panel LEDs show status at a glance, while audible alarms alert you to battery mode, low battery, overload, or fault conditions. The included USB and RS-232 ports allow integration with power management software for safe shutdown of connected systems.
