20BD156A3ANNACC0

The 20BD156A3ANNACC0 adjustable frequency AC drive, part of the PowerFlex 700 series by Allen Bradley, delivers reliable performance in rigorous operational conditions. It is rated for a three-phase input voltage of 480 VAC, accommodating industrial environments with a mains frequency of 60 Hz. The DC bus voltage stands at 648 V DC, affording robust energy management capabilities.

This model is characterized by an output current rating of 156 A, which is suitable for a variety of heavy-duty applications. The drive employs a control method incorporating both V/Hz and sensorless vector controls, optimizing performance across different load conditions. While it excels in many areas, it does not have an internal brake IGBT or a built-in brake resistor, which may affect certain braking requirements in system designs.

With a PWM frequency set at 4 kHz, the 20BD156A3ANNACC0 minimizes harmonic distortion and improves overall efficiency. The product’s design emphasizes durability, as it can tolerate shocks up to 15 G and operates effectively in environments with a vibration level of 0.152 mm.

This drive features two analogue outputs for enhanced connectivity, complementing its advanced functionality. It also has a maximum breaker rating of 450 A, providing valuable information for system integration and safety measures. Enclosed in a NEMA UL Type 1 casing, the drive retains an IP20 protection rating, ensuring basic safeguards against dust and foreign objects, making it suitable for indoor applications.
