ATV11HU18M3U

The ATV11HU18M3U adjustable frequency drive by Schneider Electric operates with remarkable efficiency, achieving at least a 98% efficiency rating. This drive is rated for power output of 0.75 kW (1 HP) and works with a 3-phase input voltage range of 200 to 230 V AC. Designed for flexible use, it handles a frequency input of 50 or 60 Hz. The output voltage capabilities extend from 0 up to 230 V AC, with a maximum output frequency reaching 200 Hz.

The device can sustain a rated output current of 4.6 A at 230 V. In terms of performance, the ATV11HU18M3U features an overload capacity of 150% of the nominal motor torque for batches lasting up to 60 seconds, which permits temporary increases in torque during starting or heavy operational loads.

Utilizing Sensorless Flux Vector Control as its control method enhances operational efficiency and responsiveness. It operates with an adjustable switching frequency in the range of 2 to 16 kHz, set at the factory to 4 kHz.

The control also allows for acceleration and deceleration ramps of up to 99.9 seconds, which can be adjusted based on the specific application needs. Additionally, the drive can provide a braking torque of 20% of the nominal motor torque without needing a braking resistor, expanding up to 150% when connected to one.

With an IP20 protection rating, the unit is suitable for indoor use, shielding components from solid objects greater than 12mm in size. The operational temperature range allows it to function at ambient temperatures from -10°C to +40°C without any derating, extending up to +60°C with proper derating measures.

Fit into compact spaces, the ATV11HU18M3U model measures 72 mm in width, 147 mm in height, and 138 mm in depth, making it efficient for various mounting configurations.
