The Allen Bradley 20AD027F3AYNARC0 adjustable frequency AC drive is engineered for versatile applications. With an operating voltage of 480 volts AC, it performs exceptionally well in three-phase configurations using a six-pulse design. The drive is capable of accommodating a continuous current rating of 27 amps, resulting in a robust power delivery of 15 kilowatts, equivalent to 20 horsepower.
In terms of its physical specifications, this model features a D-frame structure and can be mounted via a flange. It is constructed with mixed enclosures. The front chassis presents an IP20 rating, conforming to NEMA/UL Type 1 standards. In contrast, the rear heat sink is protected by an IP66 rating, making it compliant with NEMA/UL Type 4X/12 guidelines, suitable for indoor environments.
User interaction is facilitated through a full numeric keypad and an LCD interface, which provides real-time data and status during operation. An integrated Brake IGBT enhances functionality, although it does not include an internal brake resistor. The device falls under a filtered emission class, which helps minimize interference. Additionally, the 20AD027F3AYNARC0 is equipped with options for Remote I/O and DPI communication modules. For control, it offers an enhanced option, though it lacks provisions for safe torque off and has no feedback capability.
