20AB028C3AYNANC0

The 20AB028C3AYNANC0 PowerFlex 70 Adjustable Frequency AC Drive by Allen-Bradley is a digital AC drive with a CE line filter and an internal resistor brake option, which provides enhanced motor control in many applications with speed and torque control requirements. This drive features an indoor-rated IP66 enclosure which provides resistance to dust and dirt, and it is built to survive high-pressure water, and this drive also features a fast-acting current limit (20 to 160%) and the Bus Voltage Regulation which allows for acceleration and deceleration control without tripping. The 20AB028C3AYNANC0 has a 3-phase (6-pulse) input voltage of 240 Volts AC, with a minimum and maximum acceptable input range of -10% and +10% at 47 to 63 Hertz, and it has a displacement power factor of 0.98. This drive has a power rating of 10 Horsepower, with a current rating of 28 Amps, and it has an operational efficiency of 97.5%. It has a short-circuit rating of 200,000 Amps, with a 2 to 1 drive to motor power ratio, and it is designed to provide protection against a transient voltage and ground fault at the outputs. The 20AB028C3AYNANC0 monitors an excessive temperature trip at the heatsink, and it has a control logic ride-through time of 2 seconds. It has intermittent overload capacity of 115% for 1 minute and of 150% for 3 seconds and provides Class 10 motor overload protection using the I2T protection algorithm.

It can be programmed for standard volt per hertz motor control, sensorless vector control, and vector control with the patented Force technology which provides the drive with outstanding torque and speed control with feedback devices. The 20AB028C3AYNANC0, like every PowerFlex 70 drives utilizes a Sinusoidal Pulse Width Modulated signal with 4 KiloHertz programmable default frequency for frequency control, and it has a 0 to 400 Hertz programmable output frequency range, which determines the adjustable output voltage value. This drive is not designed with an encoder device, but it delivers 0.5% open-loop speed regulation across a wide speed range with slip compensation, and it also provides 0.1% speed regulation across a 120: 1-speed range and also +/-10% torque regulation. The 20AB028C3AYNANC0 has full numeric LCD human-machine interface module with a multilingual and easy-to-read 7 lines by 21 characters display, which provides easy setup and control. It has a 0 to 40 degrees Celsius (32 to 104 degrees Fahrenheit) operating range with –40 to +70 degrees  Celsius (–40 to +158 degrees Fahrenheit) storage range, at a 5% to 95% relative humidity range, and it can withstand a 15G shock for 11 milliseconds. The 20AB028C3AYNANC0 has wall/machine mount option, and it has an approximate weight of 9.13 kilograms with a shipping dimension of 219.9 x 350.0 x 179.8 millimeters.
