20BD156A3AYNADD0

The PowerFlex 700 series features the 20BD156A3AYNADD0, an adjustable-frequency AC drive tailored for demanding applications. Operating with a robust input voltage of 480 V AC in a three-phase setup, this drive excels with a continuous output rating of 156 Amps. For short bursts, it can sustain outputs of 188 A for one minute and up to 250 A for three seconds, making it suitable for high-performance tasks.

Designed for motors of up to 125 HP, the unit draws an input current of 147 Amps and supplies 122 kVA of input power. To safeguard equipment, it includes voltage trips for undervolt conditions at 280 V and overvolt scenarios at 570 V, thereby preventing potential damage from voltage irregularities.

The control mechanism utilizes sensorless/vector torque techniques for improved responsiveness and efficiency. Users can select carrier frequencies ranging from 2 to 10 kHz based on operational requirements. For feedback, it optionally accommodates a 90° quadrature encoder.

Communication within systems is facilitated by DeviceNet compatibility, ensuring effective integration into automation setups. The braking system uses IGBT technology for dynamic control, while line conditioning is achieved through an EMC filter and choke, mitigating electromagnetic interference. Lastly, the drive offers ride-through capabilities ranging from 0.5 to 2 seconds, maintaining operation during brief interruptions.
