Static frequency converter (50/60 Hz to 400 Hz) with galvanic isolation, 208 V three-phase output, IGBT technology and digital control. Ideal for airport ground power, naval, military and test bench applications. Available with battery backup on request.
The Riello Master F400 is a heavy-duty, three-phase industrial UPS rated from 30 to 125 kVA. It is engineered for harsh process environments where temperature, dust, vibration, and electrical stress all demand more from a UPS than typical IT-grade systems can offer.
Typical applications include oil and gas, petrochemical, marine, and heavy manufacturing facilities where uptime and robustness are non-negotiable.
