Frequency Converter Delivers Pure Sine Wave Output Voltage
Absopulse Electronics’ FTT 3K Series modular AC/AC frequency converter system uses microprocessor controlled, high frequency PWM technology to deliver 3-Phase, 3000VA continuous sine-wave output power, from a 3-phase input. Standard versions of the FTT 3K system provide three-phase outputs of 208 V, 380 V or 400 V (L-L) at 50 Hz, 60 Hz or 400 Hz. The output neutrals are internally connected to the chassis in “Y” configuration, which allows for phase-to-neutral voltages of 115 V, 220 V or 230 V. The FTT 3K operates from a 3-phase line voltage of 208 Vrms, 380 Vrms or 400 Vrms (L-L). 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. The input and output are filtered for low noise: the system meets EN 55022 Class A, with Class B filtering available as an option. Other options include remote shutdown or enable, output fail alarm (Form C) as well as ruggedizing and conformal coating for additional immunity to shock, vibration and humidity.
