20BD156A3AYNACD0

The 20BD156A3AYNACD0, enabled by Allen Bradley under the PowerFlex 700 series, functions as an adjustable-frequency AC drive. It is engineered to operate with a three-phase input of 480 V AC, providing adjustable output capabilities ranging from 0 to 460 V.

The drive can manage an impressive output current of 156 A, while also accommodating short-term current peaks of 188 A for durations of one minute and up to 250 A for three seconds. Operating within a typical PWM frequency of 4 kHz, this model guarantees efficient modulation for smooth operation.

In terms of motor control, this unit offers V/Hz and sensorless vector control options, allowing it to adapt to varying application needs. The accuracy of speed regulation is outstanding, maintained at ±0.01 %. Built primarily for standard environments, it features an IP20/NEMA 1 rated enclosure. The drive also integrates an IGBT brake for effective stopping capabilities.

Power efficiency is a critical aspect, as it has an internal loss measurement of 443 W and an external loss of 1,563 W under load conditions. The analog latency is recorded at 6.4 ms, facilitating timely commands. The device supports a digital I/O configuration, equipped with six inputs and three outputs, suitable for diverse system integrations.

Voltage constraints are defined, with under-voltage limits set at 280 V and over-voltage limits at 570 V, ensuring safe operation within specified electrical parameters. Overall, this drive represents a blend of efficiency, performance, and reliability in motor control applications.
