The 20BD011A3AYNADC1 adjustable-frequency AC drive from Allen Bradley’s PowerFlex 700 series is tailored for optimal motor operation. It connects to a supply rated at 480 V AC for a three-phase system, operating reliably at 60 Hz. Designed for efficiency, this unit employs a nominal input current of 9.5 A and demands an input power of 7.9 kVA. Its continuous output current is rated at 11 A, with a one-minute burst reaching 12.1 A and short-duration capability up to 16.5 A.
This drive can regulate motor output voltage ranging from 0–460 V AC and supports a maximum output frequency of 420 Hz, making it adaptable for various motor control needs. The DC bus nominal voltage is specified at 648 V DC, equipped with protection settings to prevent under-voltage at 305 V and over-voltage at 810 V.
Input protection for the AC side also features, with under-voltage set at 280 V and over-voltage at 570 V. The braking mechanism is based solely on IGBT technology to enhance braking performance. Communication capabilities include DeviceNet protocols, facilitating integration into comprehensive automation systems. The drive allows for PWM carrier frequency settings from 2 to 10 kHz, catering to diverse application requirements.
