Allen Bradley 20BD077A3AYNAND1 Used Surplus

The 20BD077A3AYNAND1 is a motor controlling drive that drives an electric motor by varying the frequency and voltage of its power supply. It is a drive with variable frequency. Using the variable frequency, the drive can control and regulate the torque of AC motors. This AC drive is 480 Volts AC unit and belongs to the PowerFlex 700 series of drives manufactured by Allen Bradley. The drive is a three-phase device and has no built-in precharge. Without the precharge, the drive should be supplied with continuous power from a three-phase source for normal operation. The 20BD077A3AYNAND1 comes with a ton of performance and protection feature. The drive features different drive tripping condition including the AC input overvoltage trip, AC input undervoltage trip, Bus Overvoltage trip, Bus undervoltage Shutoff/Fault, and nominal bus voltage. The drive supports a different algorithm which includes the Volt/Hertz, vector control and the Sensorless vector control.

The 20BD077A3AYNAND1 drive comes with integral EMC filtering and comes with a built-in DC bus choke common mode cores and common mode capacitors which can provide a packaged solution for meeting the EMC requirements including CE in Europe. The drive features a fast acting current limit and bus voltage regulation which can help produce maximum acceleration and deceleration without any tripping. The drive comes with ground fault protection, which can help verify the reliability of the drive during the startup and the running of the drive. It continuously monitors the drive and alerts the operator if needed. The drive comes with motor overload protection which can save the drive from damages. The drive also comes with motor overtemperature protection to save the drive from damages due to overheating. To control the overheating, the 20BD077A3AYNAND1 is equipped with a heat sink thermistor controlled by a microprocessor. The thermistor trips the drive if it detects an overtemperature inside the drive.
