Constructed for high-performance environments, the Allen Bradley 20BD156F0AYNAND0 adjustable-frequency AC drive offers significant versatility and reliability. This drive delivers a continuous output current of 156A, with capabilities extending to 188A for one minute and a peak of 250A for up to three seconds, ensuring sufficient power for a variety of motor types.
With output voltage ranging from 0 to 460V AC, it is appropriate for motor applications up to 125 HP non-duty and 100 HP heavy-duty classifications. The drive is encapsulated in an IP54-rated enclosure, providing protection against dust and moisture, making it suitable for less than extreme environmental conditions. Integrated within the design is an IGBT brake, without the presence of an external resistor, thus simplifying system configuration.
Control is achieved via a vector control method, complemented by 120V digital and analog I/O capabilities. This unit’s maximum output frequency can reach up to 420 Hz, accommodating applications that require fast response times. The input current rating is 147A, supporting a voltage range of AC from 280 to 570V and DC from 305 to 810V.
For input/output configurations, the drive includes 6 digital inputs and 3 digital outputs alongside 2 of each type of analog I/O, enhancing its adaptability to various control systems. The PWM carrier frequency operates at 4 kHz, with an adjustable range between 2 to 10 kHz, ensuring efficient motor operation.
Adjustable acceleration and deceleration times can span between 0 and 3600 seconds, with a resolution of 0.1 seconds allowing for precise control over motor startup and stopping. Power loss management indicates an internal heat loss of 443 W and an external heat loss of 1563 W, ensuring effective thermal management during operation. Overall, the 20BD156F0AYNAND0 serves as an advanced solution for intricate motor control demands.
