Allen Bradley 20BB070A0ANNANC0 PowerFlex 700 AC Drive 70 A 25 Hp 20B

The Allen-Bradley 20BB070A0ANNANC0 PowerFlex 700 Adjustable AC Drive is a variable frequency drive in the PowerFlex 700 series with normal and heavy-duty ratings and with a CE rated environmental filter. It is used for the speed control of a wide range of industrial motors. It has a NEMA Type 1 indoor enclosure with a conformal coating and it comes with a mounted brake resistor and a vector motor control with 24V DC I/O. The 20BB070A0ANNANC0 has a 3-phase operating voltage of 240A AC, with -+10% input tolerance at 47 to 63Hz, and its output current is 70A. The drive’s operating power rating is 20HP, and the rating is 20HP for normal and heavy-duty operations, and it offers internal filtering. It offers AC under/over voltage trip, with DC BUS under voltage and voltage trips of 204V DC and 40V DC, and it provides high-temperature detection using a heat sink thermistor. The 20BB070A0ANNANC0 has a power ride thru time of 15ms, with a logic ride thru time of 2s, and it provides protection against surge, phase-to-phase, and phase-to-ground, using installed Metal Oxide Varistors.

The 20BB070A0ANNANC0 provides motor control through the sensorless vector control and the volts per hertz control, using Pulse Width Modulated Signals with a programmable 2 to 10 KHz frequency (carrier), and with an output frequency range of 0 to 40Hz, proportional to the output voltage between 0 and the rated motor voltage. It has 2 analog (bipolar voltage or current) inputs, with 2 (bipolar voltage or current) analog outputs, and it has 6 24V DC digital inputs, with 3 (Form A, B, and C) Relay outputs. The 20BB070A0ANNANC0 has a normal duty overload capacity of 110% for 60s, with a 150% capacity for 3s, and a heavy-duty overload capacity of 150% for 60s and 200% for 3s, and it comes with a standard Internal Break Resistor. The drive does not come with Human Interface Module, a communication module, and a feedback device, but it is enclosed in an indoor, general purpose NEMA Type 1 enclosure. It has a working temperature range between 32 and 122 °F, at a non-condensing humidity range of 5 to 95%, and a storage temperature range of -40 to 158 °F. It is designed to withstand a 15G operating shock for 11ms, and a peak operating vibration of 1G, and it can function without de-rating at a maximum altitude of 1000m. The 20BB070A0ANNANC0 has total dimensions of 300mm x 583mm x 270.3mm and it is CE, UL, c-UL, and C-TICK certified.
