Schneider Electric's ATV28HU41M2U functions as an adjustable speed drive (ASD) tailored for efficient motor control. This device is compatible with single-phase input voltages ranging from 208 V to 240 V, with acceptable tolerances of -15% to +10%. Designed to handle input frequencies of 50 or 60 Hz, it features a permissible variation of ±5%. The drive's output frequency spans from 0.5 Hz to 400 Hz, providing a wide range of operation to meet various application needs.

The maximum output voltage reflects the incoming voltage, ensuring consistency in performance. Rated for an output current of 11 A, the drive can accommodate motors with a power capacity of 2.2 kW (3 HP). Furthermore, it can handle a transient output current of 15 A for durations not exceeding 60 seconds, offering significant flexibility during startup conditions. For sustained operation at rated load, total dissipated power is calculated at 107 W, and it has a short-circuit current rating of 1 kA for safety.

The switching frequency of this ASD can be adjusted between 2.0 kHz and 15 kHz to match specific application requirements. The braking torque capability is rated at 30% of the nominal motor torque without dynamic braking, or up to 150% when dynamic braking via a resistor is employed. Enclosed with an IP20 rating, this unit meets NEMA 1 and UL open type standards, indicating adequate protection for typical industrial environments. Operating effectively across an environmental range of 14°F to 104°F (-10°C to +40°C) is possible without needing to remove the vent cover, ensuring easy maintenance and operation in a variety of settings.
