20BD156A3ANNADN0

The 20BD156A3ANNADN0 from Allen Bradley is categorized as an adjustable frequency AC drive within the PowerFlex 700 series. Constructed to handle a mains frequency of 60 Hz, this drive provides a substantial output current capacity of 156 A while operating on a DC bus voltage measured at 648 V DC.

Its input requires a 480 VAC supply and is configured for a 3-phase system, ensuring compatibility with many industrial applications. The device achieves its operational efficiency with a pulse width modulation (PWM) frequency set at 4 kHz, allowing for precise control of the output voltage that ranges from 0 to 460 VAC.

Featuring an IP20 protection rating, the drive is safeguarded against dust and small solids but is not designed for exposure to moisture. The build has been subjected to tests showing it can endure shock levels of up to 15 G, which adds to its durability for demanding environments.

With two analogue outputs available, it allows for data integration into analoguous monitoring setups. However, it lacks a built-in brake resistor and does not contain an internal brake IGBT, which may affect braking capabilities in certain operational scenarios. Additionally, the circuit breaker current rating is specified at 450 A, supporting the drive's protection under fault conditions. The vibration level maintained during operation is 0.152 mm, ensuring reliability in stationary and dynamic applications.
