The 22D-B012H204 PowerFlex 40P Adjustable Frequency Drive from Allen-Bradley is a variable frequency drive used for controlling 3-phase induction motors in closed loop-applications where speed control is involved. The drive offers a compact design, with flexible operational modes, and it is digitally controlled for repeated, and precise control and operations. It has 240V AC (3-phase), operating voltage, with 12A output current and 2.2kW (3HP) output power, and its input line tolerance is ±10% at 47 to 63Hz. The 22D-B012H204 has a displace power factor of 0.98 across the whole speed range, and a maximum short-circuit rating of 100,000A. The 22D-B012H204 offers BUS over-voltage and under-voltage trips, with 200% and 300% hardware and instantaneous current fault trips, and it provides phase-to-phase plus phase-to-ground protection, as well as transient line protection of up to 6000V. It has a power loss ride thru time of 100ms, with a 2s Logic ride thru time, and it comes with DC dynamic braking using an internal IGBT transistor.

The 22D-B012H204 employs the Sensorless vector control and the standard volt per hertz control for its motor control rating using Pulse-Width Modulated signals, with 2 to 16 kHz carrier frequency for output control, and it has a programmable output range of 0 to 500Hz, with an output voltage range of 0 to the rated motor voltage. The drive has digital and analog inputs with accuracy ratings within ±0.05%, and 0.5% of the set output frequency, and it has 7 digital inputs (5 programmable, and 2 dedicated), with Sink and Source Modes that are selectable via a DIP switch setting. The 22D-B012H204 also has 2 isolated –10 to 10V and 4-20mA analog inputs, with 100-kiloohm and 250-ohm input impedance, and it has 1 non-isolated 0 to 10V or 4 to 20mA analog output, with a Form C Relay output, with 3A and 0.5A resistive and inductive ratings at 30V DC, 125V AC, and 240V AC. The drive comes with a 4-digit display/fault reset human interface module, which allows users to change the display parameters and to reset the drive in the case of faults, and it has an integral RS485 communications port, which allows for programming through a PC. The 22D-B012H204 is a plate drive device, with an IP20-rated enclosure, and it has a designated working temperature limit of –10 to 50°C (14 to 122°F) at 5 to 95% non-condensing humidity. It is CE, and cUL-us certified and its shipping dimensions are 130mm x 260mm x 180mm, with a net weight of 4.3Kg.
