The FTT 3K Series is a rugged, modular AC/AC frequency converter system that uses microprocessor controlled, high-frequency PWM technology to deliver 3-Phase, 3000VA continuous sine-wave output power from a 3-phase input. It is a mature design with a track record in numerous applications. The standard 3-phase outputs are 208V, 380V or 400V (L-L). The output neutrals are internally connected to the chassis in “Y” configuration, therefore the phase-to-neutral voltages (115V, 220V or 230V) are also available. The mechanical size of the system depends on the input/output combination. Full electronic protection eliminates the possibility of failure due to abnormal operating conditions, including application errors. Low component count and the use of components with established reliability results in high MTBF. Cooling is by built-in fans, which draw air into the unit. The FTT 3K is manufactured at our plant under strict quality control.
