The Eaton Cutler-Hammer SVX020A24A1B1 SVX9000 Adjustable Frequency Drive is part of the SVX9000 family of open drives, which provides excellent motor control in a range of industrial applications. It features digital motor control for repeatable and reliable/precise operation, and it provides inbuilt electronic motor overload protection designed to meet NEC requirements. The SVX020A24A1B1’s drive rating is 20 Horsepower, with a line EMC Level H 3-phase input range of 380 Volts AC to 500 Volts AC (480 Volts AC nominal) at 50 and 60 Hertz, and its acceptable input tolerance is -15%/+10% at 45 to 66 Hertz. Its short-circuit rating is 100,000 Amps, and it provides overvoltage and under voltage protection, as well as input phase supervision, which trips if any input phase is missing. The SVX020A24A1B1 is also safe from excessive temperatures, motor stalling, motor under load, and motor overload, and it has a programmable overcurrent trip with a limit up to 4 times of the rated input current. The SVX020A24A1B1 has motor control from the sensorless vector control, using a Pulse Width Modulated frequency with an adjustable range of 1 to 16 KHz, and its output frequency range is 0 to 320 Hertz, while its selectable output voltage range is 0 to the rated voltage.

It features 2 separated and programmable acceleration and deceleration times that are programmable from 0 to 3000 seconds, and its programmable output current overload limit is 250% of the rated output current for 2 seconds. The SVX020A24A1B1 provides up to 100% braking torque with its DC internal brake chopper circuit, and it has a field weakening point range of 20 to 320 Hertz. It has 2 programmable (0 to 10 Volts DC or 4 to 20 mA) analog control inputs, 6 digital 24 Volts DC control inputs, 1 digital 48 Volts DC open collector output, 2 programmable Form C relay outputs, and 1 10-bit analog output. Its operating temperature range is 10 to 50 degrees Celsius (4 to 122 degrees Fahrenheit) at 0 to 95% noncondensing and non-corrosive humidity, and it has a storage temperature range of -40 to 70 degrees Celsius (-40 to 158 degrees Fahrenheit). The SVX020A24A1B1 is built to operate efficiently with 100% load capacity at a maximum altitude of 1000 meters without de-rating, and it can completely resist 15 G of shock for 11 milliseconds, and 1G of vibration at 15.5 to 150 Hertz. It is protected by a NEMA Type 12 rated indoor use enclosure, and it weighs approximately 19.0 kilograms with total dimensions of 558.0 x 237.0 x 195.0 millimeters.
