Frequency converters and regulated AC supplies
Static and rotary frequency converters
Static and rotary frequency converters delivering 50, 60 or 400 Hz AC for ships, aircraft and labs.
Overview
What it does
Statcon Energiaa offers static frequency converters (SFC) and rotary frequency converters (RFC) that convert 50/60 Hz input to 50/60 Hz or 400 Hz output in 1-phase and 3-phase configurations.
SFCs use IGBT-based AC-DC and DC-AC stages with DSP control, while RFCs use a motor-driven alternator with VFD soft start and an automatic voltage regulator.
Units are supplied as skid-mounted panels, wheel-mounted trolleys or containers, with cables and connectors.
Applications
- Shore power conversion for ships and submarines
- Aircraft testing and powering of aircraft systems (400 Hz)
- Radar testing
- Tank manufacturing and maintenance
- Laboratories and industrial test benches
Features
Why engineers choose it
