Allen Bradley 20BD248A3ANNADN0 PowerFlex 700 AC Drive 20B

The 20BD248A3ANNADN0 is a VFD which can drive a 3-phase induction motor by altering the frequency and voltage. This drive has been designed and manufactured by Allen-Bradley. This drive from Rockwell Automation can control and regulate the high torque requirements of AC motors. This AC drive run with a power supply of 480 Volts AC. This drive comes from the family of Allen-Bradley PowerFlex 700 drives and the drive is housed inside a conformally-coated body. No precharge is present in this drive. A panel mount can be used to mount the drive in an indoor location. The enclosure of the mount is not water-resistant. The 20BD248A3ANNADN0 has different drive features which play an integral role. The drive has different algorithms to control the torque which includes the Volt/Hertz control, vector control, and the sensorless vector control.  The sensorless vector control is used for high torque production over a wide speed range. The vector control is used for enhanced torque regulation and excellent low-speed performance.

The drive features inertia ride-thru which can offer tripless operation during long power outages. It uses rotating energy stored in high-inertia and low-friction loads. The 20BD248A3ANNADN0 introduces ground fault protection. It is a system protective feature. It runs a diagnostic during the startup and the running of the drive. It verifies the reliability of the drive. The drive also comes with motor overload protection which prevents damage to the drive from overloading. The drive has the ability to support 2 different intermittent overloads. The 20BD248A3ANNADN0  can support a 110% overload capability for up to 1 minute and a 150% overload capability for up to 3 seconds. It also features a proactive current limit which can be programmed from 20 to 160% of the rated output current.
