When a pump skid outgrows its starter
A retrofit team replacing a across-the-line pump starter faces a familiar constraint. The motor must ramp gently, the panel depth is fixed, and the controls network is already RS-485. The Allen-Bradley 22C-B012F103 answers that brief as a PowerFlex 400 AC adjustable-frequency drive rated 2.2 kW (3 HP) and 12 A continuous output current, fed from a 200…240V AC three-phase supply.
Electrical specifications that define the duty
The drive accepts 200…240V AC, 3-phase input with ±10 % voltage tolerance and 48…63 Hz input frequency. Its output section delivers 0…230V three-phase at a programmable 0…320 Hz. Because the input stage uses isolated gate bipolar transistors, efficiency reaches 97.5 % at rated amps and nominal line voltage. Displacement power factor holds at 0.98 across the entire speed range, which keeps upstream loading predictable.
Isolation matters where control and power share a cabinet. One analog input is isolated, accepting –10…+10V or 4…20 mA, while the second analog input is non-isolated. The RS-485 DSI port on the RJ45 connector carries Modbus RTU, Metasys N2 and P1-FLN traffic, so the drive can join an existing building or process network without an added card.
Key parameters at a glance
- Input voltage: 200…240V AC, 3-phase, ±10 % tolerance.
- Output current: 12 A continuous at 45 °C and at 50 °C surrounding air.
- Output power: 2.2 kW (3 HP) with 110 % overload for up to 1 min.
- Isolation: one isolated analog input; RS-485 DSI communication port.
- Enclosure: IP20 / NEMA/UL Type Open flange mount, Frame C.
- Control method: sinusoidal PWM, Volts/Hertz.
- Carrier frequency: 2…10 kHz, rating based on 4 kHz.
- Ambient range: -10…+50 °C without derating in the open enclosure.
Why the flange-mount format suits crowded panels
Frame C flange-mount drives dissipate 146 W as an IP20 open unit. The heatsink passes through the mounting plate, so the heat load leaves the enclosure instead of recirculating inside it. Overall assembly dimensions are 325.0 mm high by 300.0 mm wide, with a depth split across the flange. A 22-JBAC kit converts the unit to IP30 / NEMA 1 / UL Type 1 when the panel interior must be protected.
Integration and network wiring
The built-in DSI port supports Modbus function codes 03, 06 and 16, with Logic Command at register 8192 and Reference at 8193. Multi-drop RS-485 wiring uses shielded two-conductor daisy-chained cable, terminated at both ends. C103 sets the data rate from 1200 to 38.4K bit/s, and C104 sets the node address from 1 to 247. For BACnet, DeviceNet, EtherNet/IP, PROFIBUS DP, ControlNet or LonWorks, a 22-COMM adapter is required, and a Frame C drive then needs the 22C-CCC adapter cover.
An external 22-RF034-CS line filter is required for EN 61800-3 compliance because the catalog emission class is 0, meaning unfiltered. The drive provides no branch short-circuit protection, so install input fuses or a circuit breaker; the published recommendation is a 20 A UL Class J, CC, T or Type BS88 fuse.
Commissioning and upkeep
Set the carrier frequency in A168, defaulting to 4.0 kHz. Two independent accel and decel ramps span 0…600 s in 0.1 s steps. For stopping, P037 selects DC injection braking, with A176 setting brake time and A177 setting brake level. Periodic inspection should confirm fan airflow, terminal torque and a clean heatsink; the drive must not be installed where the atmosphere contains volatile or corrosive gas, vapors or dust.
Questions engineers ask before specifying
What input voltage does the 22C-B012F103 require?
The Allen-Bradley unit accepts 200…240V AC, 3-phase input with ±10 % tolerance and 48…63 Hz input frequency. Single-phase operation provides 35 % rated current.
How much output current is available at 50 °C?
The published rating is 12 A at 45 °C and 12 A at 50 °C surrounding air for this rating code, so the continuous output current does not change between those two ambient points.
Is the analog input isolated?
Yes. One analog input is isolated and accepts –10…+10V or 4…20 mA with 10-bit resolution. The second analog input is non-isolated and accepts 0…10V or 4…20 mA.
Does the drive include an EMC filter?
No. The catalog emission class is 0, Not Filtered. An external 22-RF034-CS line filter is required for EN 61800-3 compliance.
