Allen Bradley 20BC8P7A0AYNANC0 PowerFlex 700 AC Drive 8.7 A 4 kW 20B

The Allen-Bradley 20BC8P7A0AYNANC0 PowerFlex 700 Adjustable Frequency AC Drive is a variable frequency drive with enhanced motor control option, designed to provide accurate control of 3-phase induction motors in many motion control processes. This drive features flexible programming system, which allows for easy linking of the already configured application parameters into existing ones, and this feature allows for up to 3 user sets (programmed parameters) which can be utilized via a simple recall function. The 20BC8P7A0AYNANC0 has a voltage rating of 400 Volts AC with 8.7 Amps of current and a power rating of 4.0 Horsepower. It has a 0.98 power factor, with a 97.5% control efficiency at the nominal rating, and a branch circuit protection rating of 200,000 Amps using the recommended fuses and circuit breakers. It offers BUS voltage regulation, designed to automatically sense a BUS voltage increase caused by regenerative electricity, and compensates for this increase by increasing the output frequency to counteract the BUS voltage increase.

The 20BC8P7A0AYNANC0 offers efficient current limiting, which prevents against overload, and it comes with factory-fitted meal oxide varistors, which provide phase-to-phase protection and line transient protection for smooth operation. It provides precise digital control using a pulse-width modulated signal, and it provides adjustable output voltage which correlates with the output frequency. The 20BC8P7A0AYNANC0 has an enhanced vector motor control option, which establishes a direct connection between output frequency and output voltage for reliable speed control and it has a slip compensation feature which can be enabled by users for accurate speed control. It is programmed for any of the multiple stop options depending on application needs, and it has 2 acceleration/deceleration times, independently programmed from 0 to 3600 seconds for optimized performance. The 20BC8P7A0AYNANC0 has a dynamic brake transistor option which offers a cost-effective means of switching regenerative energy, and it has a CE rated EMC line filtering with internal DC BUS choke for smooth performance. The 20BC8P7A0AYNANC0 has a NEMA Type 1 enclosure, which weighs approximately 18.0 pounds (with the drive), and it has total dimensions of 4.33 x 13.23 x 7.87 inches.
