20AD8P0A3AYNANC0

The 20AD8P0A3AYNANC0 is a PowerFlex 70 series AC drive manufactured by Allen-Bradley. Its power ratings are 5 Horsepower, 3.7 kW, 480 Volts AC input voltage, and it weighs 3.6 kilograms (7.9 pounds). This AC device features microprocessor-based control which is tested to perfection to ensure that it is suitable for 3-phase motor industrial speed control. The 20AD8P0A3AYNANC0 can be applied in many different industrial and commercial applications. It is already installed in fan control systems for air conditioning and heating process control. This motor controller also aids in changing the speed of pumps and blowers. It is often implemented in conveyors, machine tools with lower power demands, and with fiber-spinning machines. The 20AD8P0A3AYNANC0 incorporates an enhanced control that does not require encoder feedback for outstanding open-loop control.

The module has an internal voltage reduction mechanism designed to prevent damage from possible overvoltage situations. In the heart of the control system, in the 6-pulse inverter stage of the signal forming process, the driver uses IGBTs which are turned on and off in the appropriate sequence to regulate the frequency and voltage sent to the motor. All IGBTs are controlled and activated by a microprocessor which monitors various parameters measured by the drive to run the correct IGBT activation sequence. The 20AD8P0A3AYNANC0 drive features an IP20 (open) enclosure, and it should be installed with a fuse for short circuit protection. To ensure effective heat dissipation, spaces of 3 inches on the bottom and top sides should be reserved. To be sure that there will be no signal interference, route the incoming and outgoing cables of the drive away from equipment that is electrically sensitive.
