The 20BD156A3NNNANC0 model is an adjustable-frequency AC drive from the PowerFlex 700 line by Allen Bradley. It is designed to operate with a 480 V AC three-phase input at 60 Hz. This drive is capable of achieving a maximum frequency of 420 Hz, making it versatile for various applications. The pulse width modulation (PWM) frequency operates in a range of 2 kHz to 10 kHz, rated at 4 kHz for typical applications.

This unit delivers a continuous output current of 156 A which can support motors rated up to 125 HP under normal duty scenarios and 100 HP for high duty situations. Overload capacity enables handling 188 A for 1 minute and allows for bursts up to 250 A for 3 seconds in high duty. The input current is specified at 147 A at 480 V, while input power requirements reach 122 kVA under the same conditions.

The nominal DC bus voltage is registered as 648 V DC. Notably, this drive does not come with brake IGBT or resistors for braking functionality. It also includes an LCD display with a keypad for user interface and control. In terms of I/O capabilities, the drive counts 2 analog inputs, 2 analog outputs, 6 digital inputs, and 3 digital outputs to facilitate a range of functionalities. Voltage trip settings include AC undervoltage at 280 V and overvoltage at 570 V, along with DC undervoltage at 305 V and overvoltage at 810 V, enhancing operational safety.
