Absopulse Debuts FTT 12000 Frequency Converter

Absopulse Electronics Ltd. (Carp, Ontario, Canada) debuted its new FTT 12000 frequency converter, which delivers 12 kVA, three-phase, sinusoidal power from a three-phase input. The unit was designed for the conversion of three-phase, 208 Vrms/60 Hz inputs to three-phase 380 Vrms/50 Hz outputs, or conversely, of 380 Vrms to 208 Vrms. The FTT 12000 can also be modified for various output voltages and for 400 Hz applications. The output phases are connected in a "Y" configuration and can either be grounded or left floating.

The system incorporates high-frequency, pulse-width modulation technology to synthesize a precision-regulated, sinusoidal wave-form with less than 5 percent total harmonic distortion at full load. The unit is fan-cooled and rated for operation over 0 °C to 50 °C. The converter is housed in four, stacked 4 in x 19 in x 15 in enclosed chassis, three for the ac-dc conversion and one for the dc-ac conversion. The entire system weighs 72 kg.

Other frequency converters in this line include 1,500 VA, 3,000 VA and 6,000 VA models, available with either single-phase or three-phase inputs and outputs. Absopulse also offers an extensive range of single-phase and three-phase sine-wave inverters in the 30 VA to 10 kVA power range. The FTT 12000 is priced at $11,600 each.
