Absopulse Electronics' FTT 3K series is a rugged, modular AC/AC frequency converter system that uses microprocessor controlled, high-frequency PWM technology to deliver three-phase, 3000VA continuous sine-wave output power, from a three-phase input.
Standard versions of the device provide three-phase outputs of 208, 380 or 400V (L-L) at 50, 60 or 400Hz. The output neutrals are internally connected to the chassis in "Y" configuration, which allows for phase-to-neutral voltages of 115, 220 or 230V. The device operates from a three-phase line voltage of 208, 380 or 400Vrms (L-L).
High frequency conversion enables a compact construction, low weight and high efficiency. The device is suitable for critical applications. The input and output are filtered for low noise. The device 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 ruggedising and conformal coating for additional immunity to shock, vibration and humidity. Full electronic protection eliminates the possibility of failure caused by abnormal operating conditions, including application errors.
The mechanical size of the device depends on the input/output combination, and varies from a 3Ux19inch rack to a 6Ux19inch. Cooling is by built-in fans.
The device is available with output power levels of up to 12kVA. Custom versions provide high output power.
