Single phase input to 3-Phase output AC-AC frequency converter
3-phase AC-AC frequency converter uses field-proven microprocessor controlled high frequency PWM technology to generate up to 1kVA output power with pure sine wave output voltage.

The FTP 1K-F7W series frequency converters 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. This frequency converter also accepts 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.
Applications
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.
EMI, safety standards, electronic protection
Protection features include 3000Vdc input to output isolation, inrush current limiting, reverse polarity protection, and output current limiting with short-circuit protection. The three phase inverters comply with EN 62368-1 and equivalent safety standards. Filtering on the input and output contributes to low output ripple and noise. The input meets the EMI requirements for EN 55032 Class A with wide margins. Class B is available on request. The unit can therefore be used in EMI sensitive environments without additional filtering.
Cooling and mechanical construction
High quality built-in fans provide sufficient airflow for operation over a 0°C to +50°C temperature range with no requirement for derating. The fans draw air into the unit, and exhaust at the terminal side of the unit. The heat generating components are on aluminum heatsink blocks and thermally connected to the base plate. This also ensures exceptional mechanical ruggedness.
Heavily ruggedizing ensures immunity to high levels of shock and vibration (IEC 61373 Cat 1 A&B). Conformal coating protects the printed printed circuit boards from the effects of humidity and airborne contaminants.
