The 20AD027A2AYNANC0 from Allen Bradley is classified as an adjustable frequency AC drive, tailored for sophisticated motor control applications. Operating effectively with an input voltage of 480 VAC in a 3-phase setup, this drive is rated to offer up to 20 horsepower in normal duty, as well as 15 horsepower for heavy-duty scenarios. It outputs a continuous current of 27 A, ensuring robust performance during operation.
Equipped with an enhanced control level featuring 24 V DC I/O, this unit does not provide feedback capability. The drive can manage a range of carrier frequencies, from 2 kHz intended for standard operation to higher frequencies of up to 12 kHz in vector applications, allowing for versatile motor control and precise performance.
This model has a panel-mount enclosure rated to IP20 and is compliant with NEMA 1 standards, which provides adequate protection for use within environments that do not expose it to harsh conditions. The human-machine interface (HMI) integrates an LCD display alongside a digital keypad, facilitating user interaction and control.
The drive includes a brake IGBT module, but it is important to note that it does not come with a brake resistor. Additionally, the unit meets CE compliance for electromagnetic compatibility (EMC) according to the 89/336/EEC directive, ensuring that it can operate safely within its specified limits without causing electromagnetic interference.
