The Allen Bradley 20BD011A3AYNADD1 provides an advanced solution for motor drive applications, functioning as an adjustable-frequency AC drive. Designed for three-phase power supply at 480 V AC, it offers versatility with its output voltage range from 0 to 460 V AC. The continuous current capacity is 11 A, with additional overload abilities of 12.1 A for up to one minute and 16.5 A for short bursts of three seconds.
Ideal for demanding environments, this drive's upstream protection includes breakers rated at a maximum of 40 A and fuse ratings between 15 to 40 A. In terms of frequency management, the drive operates with PWM frequencies from 2 kHz to 10 kHz, allowing it to meet specific application needs efficiently. The maximum achievable frequency is set at 420 Hz.
Control is handled through two methods: Volts/Hertz and Sensorless Vector, yielding efficient performance characteristics for a range of applications. The IGBT braking feature enables optimal deceleration without the need for an additional resistor.
For effective monitoring and communication, the 20BD011A3AYNADD1 is compatible with DeviceNet. Input draw during operation reaches 7.9 kVA. It can endure power interruptions with a ride-through capability of between 0.5 to 2 seconds, ensuring reliable operation under fluctuating conditions. AC protection covers voltages from 280 to 570 V and DC protection from 305 to 810 V, making it robust against voltage fluctuations.
