The 20BD156A3NYNANA0 is an adjustable-frequency AC drive from the Allen Bradley PowerFlex 700 lineup. Designed for versatile industrial applications, it accepts a three-phase input voltage of 480V AC at 60 Hz. This drive’s output current is rated at 156 amps for continuous operation, with brief surge capacities of 188 amps for one minute, and 250 amps for three seconds.

The unit features a configurable output frequency ranging from 0 to 400 Hz, and with vector control, this can extend up to 420 Hz. It employs a sine-coded PWM control method, along with any programmable carrier frequency of 2, 4, 8, or 10 kHz. The built-in LCD with a keypad interface simplifies configuration and monitoring, enhancing user interaction.

Its cooling system operates through natural convection, contributing to its compact and efficient design. The drive's enclosure is rated at IP20 / NEMA 1, establishing a protective barrier against dust and incidental contact.

This model incorporates an installed brake IGBT but does not include an internal brake resistor. Communication is facilitated via RS-485 using Modbus RTU protocol, while a common mode choke serves as the EMC filter, ensuring compliance with electromagnetic compatibility standards. The impressive efficiency of the drive reaches up to 97.5% when operating at the rated load. It is suitable for ambient operating temperatures spanning from 0 to 40°C (32 to 104°F), ensuring reliable performance in a range of environments.
