20AC8P7A0AYNNDNN

The 20AC8P7A0AYNNDNN PowerFlex 70 Adjustable Frequency AC Drive is an Allen-Bradley designed AC digital drive with DeviceNet control capability designed to provide all-around motor control solutions in most simple fan and pump applications. All PowerFlex 70 AC drives feature a factory embedded dynamic braking transistor which provides a means for switching regenerative energy during slowing, and they all have the inertia ride-through function which allows for tripless operation in the event of an unmitigated power loss. The 20AC8P7A0AYNNDNN is a frame B drive with 400 Volts AC voltage class and with 8.7 Amps and 5.0 Horsepower drive output ratings. It has an outstanding power factor of 0.98, with an operational efficiency of 97.5% at the nominal voltage, and it offers 200,000 Amps circuit protection using specified circuit breakers. It has built-in protection against excessive temperatures, transient faults, and ground faults, and it also has current limiting and BUS voltage regulation for optimized operation.

The 20AC8P7A0AYNNDNN offer inertia ride-through (a function which provides users with faultless operation even in a short power loss), and slip compensation (a function which helps deliver 0.5% open-loop speed regulation) for accurate speed control. It is factory programmed for the Volts per Hertz motor control method, suitable for simple pump and fan applications, and it utilizes a pulse width modulated signal with a programmable carrier frequency for control. The 20AC8P7A0AYNNDNN offers adjustable 3-phase output voltage, controlled via programmable output frequency, with accuracy within ±0.01% of the set output frequency. It has DeviceNet communication capability, via an internal DeviceNet communication interface which allows for easy control, monitoring, troubleshooting, programming, and seamless transfer of files from the host controllers. The 20AC8P7A0AYNNDNN has a panel-mounted IP20 rated enclosure, and it has a 0 to 50 degrees Celsius ambient temperature range. It has an average mounting weight of 8.0 pounds, and aggregate dimensions of 6.78 x 9.2 x 7.1 inches.
