The PowerFlex 700 series includes the 20BD077A3NNNADA0, an adjustable frequency AC drive specifically engineered for handling demanding applications. With a voltage range of 480 VAC, this drive is optimized for 3-phase utilization. It supports line frequencies of 50 or 60 Hz, adapting to various system requirements.
This unit is rated for a current of 77 A and delivers an impressive 60 horsepower (45 kW) of output power, making it suitable for substantial motor control tasks. The drive is classified under size category 4, ensuring a compact footprint while maintaining performance capabilities. Protection against dust and objects is guaranteed by an IP20 rating, which aligns with NEMA 1 standards, allowing for indoor use.
User interaction is facilitated through a full numeric LCD human interface module, allowing for simplified monitoring and control. The drive communicates using a DeviceNet communication block, enhancing system integration. Notably, this model lacks IGBT-type or resistor-type braking systems, focusing instead on standard I/O and control methodologies utilizing 24V DC/AC. Additionally, it does not incorporate feedback mechanisms, which may suit specific applications where such features are unnecessary.
