20BD156A3ANNARC0

The adjustable-frequency AC drive model 20BD156A3ANNARC0 from Allen Bradley’s PowerFlex 700 series provides high performance for industrial applications. Designed for continuous operation, it delivers an output of 156 A. The drive supports normal motor operations at up to 125 HP and can handle heavy loads, functioning up to 100 HP.

Operating on a 3-phase input at 480 V AC and 60 Hz, the drive allows users to adjust output voltage within a range of 0 to 460 V AC. It features protection trips for overvoltage around 810 V DC and undervoltage at approximately 305 V DC, ensuring the system maintains operational integrity under varying conditions. The input current of approximately 147 A supports robust performance.

The drive can endure short bursts of high current with a short-term capacity of 188 A for one minute and 250 A for three seconds, accommodating transient loads effectively. Operating with a selectable PWM frequency between 2 and 10 kHz, it allows for flexibility to match specific application needs. Control modes such as V/Hz, sensorless vector, and full vector are available to optimize performance.

Features include a ride-through option with I/O hold capabilities lasting from 0.5 to 2 seconds, enabling continued operation during momentary power interruptions. User interaction is facilitated through a human-machine interface that consists of an LCD and full keypad, making adjustments and monitoring straightforward. With an enclosure rated at IP20 per NEMA 1 specifications, this drive is suitable for most indoor applications without exposure to harsh environmental conditions.
