20AD027A3NYNANN0

The 20AD027A3NYNANN0 PowerFlex 70 Adjustable Frequency AC Drive by Allen-Bradley is a variable frequency digital drive from the PowerFlex 70 series of high-performance drives that are built for excellent motor control in a variety of applications requiring torque and speed control. This drive features a brake transistor option designed to provide the low-cost switching of excess regenerative energy, and it also comes with a NEMA Type 1 airtight enclosure that is compatible for panel mounting. It has a 3-phase, 6-pulse, 480 Volts AC voltage class with -/+10% acceptable voltage range, and total power output ratings of 20 Horsepower. It also has 27 Amps of current rating, with a 0.95 power factor, and it has an overall efficiency of 97.5%. It comes with BUS voltage regulation and a quick current limiting capacity for smooth motor operation. The 20AD027A3NYNANN0 also has built-in temperature control, and it has field removable metal oxide varistors which provide ground fault protection and protection against a transient voltage of 6000 Volts.

This drive is programmed for the Volts per Hertz motor control method, and it utilizes a sinusoidal pulse width modulated signal for output control. It has a programmable control frequency with a range from 0 to 400 Hertz, which controls the output voltage, and it has a selectable output motor voltage depending on the desired motor speed. The 20AD027A3NYNANN0 does not come with a feedback device, but it is capable of 0.5% speed regulation across a 40:1 speed range with slip compensation, and it also offers independently programmed deceleration and acceleration times. This drive is built with CE-certified EMC line filtering, and an integral dynamic brake transistor which provides cheap but high-performance braking for smooth motor operation. The 20AD027A3NYNANN0 has a full numeric LCD interface module, with a 7-line by 21-character displays and a multilanguage text display for programming, troubleshooting, metering, and start-up. It has an IP20 (NEMA Type 1) air and dust-tight enclosure, and it is rated for use within a 0 to 50 degrees Celsius (32 to 122 degrees Fahrenheit) temperature range. The 20AD027A3NYNANN0 has a net shipping weight of 9.25 kilograms, with total dimensions of 219.90 x 350.00 x 179.80 millimeters, and it is CE, UL, cUL-us, ABS, and RCM certified.
