20BD156A3AYNAED0

The Allen Bradley 20BD156A3AYNAED0 belongs to the PowerFlex 700 series and serves as an adjustable-frequency AC drive with robust capabilities. This drive supports a power output of 125 horsepower, ideal for high-demand situations. Operating with a 3-phase input, it requires a nominal voltage of 480 V AC but can function efficiently across an input voltage spectrum of 342 to 528 V AC.

It is equipped with a considerable continuous output current rating of 156 A, allowing it to manage substantial loads effectively. The drive also has provisions for short bursts of increased current, reaching 188 A for durations of one minute and peaking at 250 A for three seconds, which proves beneficial during transient conditions. The drive's control system utilizes vector and V/f control methods, enabling precise performance tailored to specific motor requirements.

Additionally, the drive communicates via EtherNet/IP, facilitating seamless integration into modern networking systems, while feedback is provided through an open-loop configuration. The 20BD156A3AYNAED0 features both analogue and digital input/output capabilities, presenting two analogue inputs and outputs alongside six digital inputs and three outputs, enhancing its functionality in control applications. Switching frequency can be adjusted between 2 kHz and 10 kHz to meet diverse operational needs.

The structure of this drive is housed in an IP20/NEMA 1 rated enclosure, offering adequate protection against dust and incidental contact. Furthermore, it incorporates robust DC bus limits with nominal values of 648 V DC, alongside undervoltage and overvoltage protections set at 305 V and 810 V, respectively, ensuring reliable and safe operation in critical environments.
