20BD156A0ANNARC1

The 20BD156A0ANNARC1 by Allen Bradley is an efficient adjustable frequency AC drive from the PowerFlex 700 lineup. This unit operates on 480 VAC in a three-phase configuration and is capable of handling an output current of 156 amps. Designed for industrial applications, it has a nominal motor power output of 125 HP when operating under normal duty conditions, and 100 HP for heavy-duty tasks, providing sufficient performance across a variety of scenarios.

The control method used in this drive is vector control, which offers precise motor management. Feedback is provided through a standard encoder, ensuring accurate performance monitoring. This drive deals with temporary overload conditions by allowing an overload capacity of 110% for a duration of 1 minute, accommodating fluctuations in load demands effectively.

With an IP20 protection rating, this equipment is designed to operate safely in environments where dust and moisture are minimal. The communication capabilities include a Remote I/O - DPI module, facilitating straightforward integration into existing control systems. Additionally, the unit operates with a carrier frequency of 4 kHz and runs on a bus voltage of 648 V DC. Notably, the device does not include a brake IGBT or an internal brake resistor, which simplifies the overall design. The human interface module (HIM) is absent on this model, resulting in a blank plate configuration. The simplicity of the design ensures reliability, making this drive a vital component for efficient and effective control of motor functions.
