FSP UPS ST 1200

FSP UPS ST 1200
The FSP UPS ST backup power supply with Line-interactive topology provides reliable protection against power outages for your electronic devices. The unit offers an apparent power of 1200VA and a real power of 720W, providing backup time at half load. The Tower design combines stable performance with a clear LCD display and an integrated fan for optimal cooling. The rear panel includes four Schuko output sockets for connecting end devices. A USB communication interface ensures connection to a computer, and RJ-45 data network protection is in place for the security of network components. Four backed-up Schuko sockets provide a constant power supply for connected computers, servers and network elements.
Key features of the FSP UPS ST 1200 backup power supply
- Line-interactive topology balances voltage fluctuations in the mains
- Automatic voltage regulation protects connected equipment from damage
- Two batteries ensure long operation during a power outage
- Clear LCD display shows the current status of the unit
- Data network protection with an RJ-45 connector prevents damage via the LAN line
- Four Schuko sockets allow for easy connection of standard plugs
Performance and topology
The FSP UPS ST 1200 interactive backup power supply works with Line-interactive topology, which effectively stabilises fluctuations in the electrical grid. The real power reaches 720W. The efficiency of the power supply is 75.97% at 100% load and increases to 83.06% at half power consumption. The integrated automatic voltage regulation stabilises the input current without unnecessarily discharging the batteries.
Battery and protective features
The FSP UPS ST 1200 backup power supply is powered by two 12V batteries with a capacity of 9Ah, which charge to 90% of their capacity in 6 to 8 hours. The device uses a simulated sine wave with a typical transfer time of 6ms and a limit of up to 10ms. Protection systems prevent damage to connected equipment during voltage fluctuations in the range of 162V to 290V. The built-in fan keeps the operating temperature at optimal levels, and the noise level does not exceed 40dB at a distance of 1m.
