FTP 1K-F7W series frequency converters from ABSOPULSE Electronics (Ottawa, Ontario) use microprocessor controlled high frequency pulse width modulation (PWM) technology to convert an AC-input of 115Vac or 230Vac and frequency of 47…410Hz to the required 3-phase AC-output voltage and frequency. The converters also accept a universal AC-input of 95-264Vac.
Standard AC-output options include 208Vrms (L-L) 3-phase continuous at 60Hz or 400Hz, or 380Vrms or 400Vrms (L-L) 3-phase continuous at 50Hz or 60Hz. Phase-to-neutral voltages 115Vrms, 220Vrms or 240Vrms are also possible. Efficiency is typically 80% at full load, depending on the required input/output configuration. Custom input/output configurations are readily available.
The frequency converters are suitable for controlling the speed of a standard 3-phase induction motors, testing low power 3-phase equipment in engineering labs, shipboard (navy) and avionic instrumentation and equipment, and similar industrial applications.
