INET’s Model SSP54 pulse-width modulated Static Frequency Converter provides precise 400Hz power to commercial aircraft during ground operations utilizing state of the art 1GBT technology. The unit meets all power requirements of the latest commercial and military aircraft as well as 400 Hz avionics, missile, and radar equipment. This self-contained outdoor rated model is specifically designed to mount neatly in a flat configuration under a passenger boarding bridge.

The unique 24-pulse power topology results in lighter weight, lower noise, higher efficiency, and insignificant input harmonic current compared to any other unit in the field. The standard unit with low-harmonic option boasts less than 5% input harmonic current at full load.

Other models are available for alternate mounting configurations, and for 60Hz inputs (see Series SSP64).

Standard 400Hz 3-phase output voltage is 200/115V, although other voltages are available for specialized applications. Units greater than 90Kva have independently-controlled dual outputs.

Rated efficiency exceeds 93% at any load above 50%, and features independent phase regulation and full no-break transfer compatibility.

INET offers a complete line of 400 Hz equipment and systems, including related accessories and technical services.
