MF Series
1-phase input – 1-phase output1 kVA – 3 kVA
The MF Series (1–3 kVA) is a single-phase input, single-phase output online UPS family with a pure sine wave output and advanced communication options.
Using high-frequency true double conversion, the MF Series protects medical systems such as laboratory analysers, operating theatres and ultrasound devices, as well as security systems, automation, computer networks and communication systems against power cuts and energy fluctuations.
- Uninterrupted, stable power
- High protection for critical loads
- Continuous sine wave output
