Offline UPS – VFD (Voltage and Frequency Dependent)

Offline UPS, also known as Voltage and Frequency Dependent (VFD), are suitable for protecting non-critical devices such as PCs, peripherals and office equipment, or home entertainment gadgets such as TVs and games consoles against power outages.

In an offline uninterruptible power supply, the mains always powers the load. If there’s a power failure, the UPS system automatically switches to battery power.

All of Riello UPS’s VFD power supplies offer simple “plug and play” installation.
