20AC072C3AYNANC0

The Allen-Bradley 20AC072C3AYNANC0 PowerFlex 70 Adjustable Frequency AC Drive is a digital AC drive built to provide exceptional motor control in many industrial and non-industrial applications with the need for precise torque and speed control. It features enhanced control without a safe torque-OFF circuit option, but it has a factory-installed internal dynamic braking transistor, which provides a low-cost means of switching regenerative energy. The 20AC072C3AYNANC0 has a normal duty power rating of 37 kilowatts (50 Horsepower), with 72 Amps nominal current rating and a 400 Volts AC operating voltage. It has an acceptable input range of 360 Volts AC to 440 Volts AC, with a 0.98 displacement power factor, and it offers 200,000 Amps maximum short-circuit rating using the specified circuit breakers. The 20AC072C3AYNANC0 provides voltage regulation with overvoltage and under-voltage trip limits of 475 Volts AC and 233 Volts AC, and it offers current limiting with a programmable range between 20% and 160% of the rated nominal current. It provides ground fault protection and line transient protection using field-removable metal oxide installed on its circuit and it offers microprocessor excessive temperature control for precise temperature monitoring.

The 20AC072C3AYNANC0 offers up to 15 milliseconds of faultless ride-through by using the rotational energy generated by high-inertia, low-friction loads, and it has an EMC line filter which meets the CE standard and is designed to provide shielding against interference from electromagnetic noise. It has enhanced motor control option, and it can be configured for sensorless vector control or field oriented vector control method. It provides digital control by using pulse width modulated (PWM) signal, and it provides 3-phase output voltage, which is adjustable from 0 to the rated motor voltage. The 20AC072C3AYNANC0 is configured using a full numeric featured LCD human-machine interface module with multilanguage descriptive text, which also allows for start-up, metering, monitoring, and troubleshooting. It has an IP66 (NEMA 4X/12) rated indoor enclosure with a flange-like heatsink and mounting holes, and it has a 50 degrees Celsius temperature limit. The 20AC072C3AYNANC0 weighs approximately 18.6 kilograms, with approximate shipping dimensions of 280.3 x 555.8 x 207.1 millimeters, and it is ABS, CE, cUL-us, and KCC certified.
