Product description
Self-ventilation and frame size 3 define the constructional classification of the Control Techniques UNI3404. The frequency inverter belongs to the Unidrive Classic range and is documented for a maximum rated motor power of 30 kW or 40 HP. Its three-phase mains supply covers 380 to 480 V AC with a tolerance of ±10 % and 48 to 62 Hz. At 400 V, the rated device power is 41 kVA. For a switching frequency of 3 kHz and an ambient temperature of 40 °C, the operating instructions specify a rated device current of 60 A. The short-term device current reaches 90 A for 60 seconds; 105 A for four seconds is specified in closed-loop operation. The typical input current is 52 A and the maximum input current 66 A. An 80 A gG HRC fuse according to IEC 269 is listed as the mains fuse. The power terminals of frame size 3 are M8 threaded studs. The Unidrive platform supports sensorless open-loop operation and encoder-based closed-loop operation. Switching frequencies of 3, 4.5, 6, 9 and 12 kHz are available for frame size 3. The permissible continuous current decreases as the switching frequency rises; at 50 °C, the documented values range from 44 A at 3 kHz to 20.9 A at 12 kHz. The associated motor cable lengths are stated as 200, 100, 75 and 50 m for 3, 6, 9 and 12 kHz. The device uses self-ventilation and has protection rating IP40. The construction measures 335 × 375 × 260 mm in height, width and depth. The documented weight of frame size 3 is 22 kg. The complete UNI3404 identifier remains authoritative for assignment within an existing installation.
