The Mitsubishi Freqrol FR-U120S-N0.2K-EC is a general-purpose inverter that converts single-phase 220-240 VAC input into three-phase 220-240 VAC output for motor control applications up to 0.2 kW. Using sinusoidal wave PWM control, it delivers efficient variable-frequency operation across a 0.5 Hz to 120 Hz output range with maximum output current of 1.4 A. The unit measures 168 × 71 × 133 mm, weighs 1.325 kg, and integrates a front digital keypad for parameter configuration and manual operation.
