20BD156A3AYNANB0

The Allen Bradley 20BD156A3AYNANB0 adjustable-frequency AC drive is engineered to meet rigorous industrial requirements, aligning performance with reliability. With an input operational range of 380 to 528 V AC, it effectively draws power from a 480 V AC 3-phase supply. The drive's continuous output is rated at 156 A, which permits consistent operation under various load conditions. For scenarios demanding heightened performance, the drive can handle overload output currents of up to 188 A for one minute and 250 A for a short duration of three seconds, providing flexibility for dynamic applications.

For effective performance management, the DC bus nominal operates at 648 V DC, with safeguards in place, including a DC undervoltage trip threshold at 305 V DC and a DC overvoltage trip at 810 V DC. This ensures the drive remains within safe operating parameters to prevent damage during fluctuations in power supply.

The drive also features a comprehensive array of I/O options consisting of 6 digital inputs, 3 digital outputs, 2 analog inputs, and 2 analog outputs, enabling extensive interfacing with various control systems. A notable accuracy of ±0.01 % in frequency ensures precision in applications where speed control is critical, with a maximum output frequency of 400 Hz to accommodate diverse operational needs.

With an enclosure classified as IP20 / Type 1, the drive is designed for standard indoor environments, providing basic protection against solid contaminants but not intended for outdoor use. The 20BD156A3AYNANB0 AC drive exemplifies the integration of advanced technology with robust design, making it suitable for a range of automation tasks.
