AC/AC power supply / sinusoidal converter / frequency
Absopulse Electronics’ FTT 3K Series is a rugged, modular AC/AC frequency converter system. It uses microprocessor controlled, high frequency PWM technology to deliver 3-Phase, 3000VA continuous sine-wave output power, from a 3-phase input. The standard design delivers three-phase outputs of 208V, 380V or 400V (L-L) at 50Hz, 60Hz or 400Hz. The output neutrals are internally connected to the chassis in “Y” configuration, which allows for phase-to-neutral voltages of 115V, 220V or 230V. The FTT 3K operates from a 3-phase line voltage of 208Vrms, 380Vrms or 400Vrms (L-L). Other voltages, frequencies and options can be provided on request.
The FTT 3K is comprised of a number of internal modules. The mechanical size of the system depends on the input/output combination – it varies from a 3U x 19” rack to a 6U x 19”. Chassis-mount versions are available. Cooling is by built-in fans.
Full electronic protection eliminates the possibility of failure due to abnormal operating conditions, including application errors. The high frequency conversion enables a compact construction, low weight and high efficiency. These factors, as well as the exclusive use of components with established reliability, make the system suitable for critical applications. Filtering meets EN 55022 Class A, (Class B optional). Other options: remote shutdown or enable, output fail alarm (Form C), ruggedizing and conformal coating.
Absopulse’s 3-phase to 3-phase frequency converters (FTT) are available with output power levels of up to 12kVA; custom versions provide higher power. Please visit the Absopulse Electronics website for more information on this and similar designs.
