Frequency converter
10 - 740 W | MININVERT 370/740
MINIMOTOR
The MININVERT 370 and 740 are static frequency converters with PWM microprocessor system, which offer high performance features such as speed control in retroaction and position control. These models have been produced to drive small three phase motors with power between 10 and 370 W (1/2 HP) for the 370 model, and up to 740 W (1 HP) for the 740 model. They have been designed to be installed outside, on the panel, or inside the cabinet by using the related supports. A particular feature is that of fully inverter-controlled position control, which can be controlled in various ways (see the table of technical specifications). The frequency converters comply with CEI EN 61800-3 (electromagnetic compatibility standard).
OPERATING PRINCICPLES: the mains alternating voltage, suitably rectified and filtered supplies a three phase IGBT type inverter circuit based on the PWM system (pulse width modulation) which provides the motor with an equivalent three-phase sinusoidal voltage with adjustable amplitude and frequency. In this way, the motor rotates at a variable speed according to the frequency.
