22C-B012N103 | 2.2 kW 12 A AC Drive, 240V

What the 22C-B012N103 Delivers in Fan and Pump Duty

The Allen-Bradley 22C-B012N103 is a PowerFlex 400 adjustable-frequency AC drive rated 2.2 kW (3 HP) with 12 A continuous output current. Its 200…240V AC three-phase input and built-in RS-485 port make it a precise fit for variable-torque fan and pump loads.

From an engineering standpoint, This unit is specified for the exact duty it serves. The drive accepts 200…240V AC three-phase input with ±10 % voltage tolerance and 48…63 Hz input frequency. It delivers 0…230V three-phase output across a programmable 0…320 Hz range. Continuous output current is 12 A at both 45 °C and 50 °C surrounding air, so the rating holds across the published ambient band.

Key Specifications of This unit

• Input voltage: 200…240V AC, 3-phase, ±10 % tolerance.
• Output current: 12 A continuous, with 110 % overload for up to 1 min.
• Output voltage: 0…230V three-phase, programmable to 320 Hz.
• Efficiency: 97.5 % at rated amps and nominal line voltage.
• Power factor: 0.98 displacement across the entire speed range.
• Enclosure: IP20 / NEMA/UL Type Open, Frame C.
• Communication: RS-485 DSI supporting Modbus RTU, Metasys N2 and P1-FLN.
• Power dissipation: 146 W as an IP20 open drive.

This unit carries no internal EMC filter. For EN 61800-3 compliance, the external 22-RF034-CS line filter is the published selection for this rating. Similarly, dynamic braking is external: the F5 OverVoltage fault response directs users to extend decel time or install a dynamic brake chopper.

Why This unit Suits Fan and Pump Applications

Fan and pump loads reward drives that control pressure and flow without wasted energy. This unit includes a built-in PID control loop, a purge input and auxiliary motor control for up to three auxiliary motors. Consequently, a single drive can sequence lead and lag pumps without additional controllers.

In a typical supply-fan retrofit, the drive replaces a fixed-speed starter. The PID loop then trims fan speed to duct pressure, and the 0.98 displacement power factor keeps input current low across the speed range. Because the 12 A rating holds at 50 °C, the drive tolerates warm mechanical rooms without derating.

Wiring, Integration and Protection Notes

The built-in RS-485 port uses an RJ45 connector with only pins 4 and 5 wired. Modbus RTU function codes 03, 06 and 16 are supported, with Logic Command at register 8192 and Reference at 8193. Multi-drop networks use shielded two-conductor daisy-chained cable with termination resistors at each end. Repeaters may be needed beyond 32 nodes. For EtherNet/IP, DeviceNet, PROFIBUS DP or BACnet MS/TP, the 22-COMM adapter family provides the network interface; a 22C-CCC adapter cover is required on Frame C.

Protection is equally specific. A 20 A UL Class J, CC, T or BS88 fuse is the recommended input fuse, and the 140M-F8E-C16 protector is the published branch-circuit device. The 100-C23 or 100-E26 contactor completes the recommended line-up. The drive does not provide branch short-circuit protection, so input fuses or a circuit breaker must be installed. Control I/O includes seven digital inputs, two analog inputs, two Form C relay outputs and two analog outputs.

Installation and Long-Term Reliability

Mount This unit in a ventilated enclosure of at least 5098 in.3 when applied as a Type E combination motor controller. The drive is fan cooled and must not be installed where volatile or corrosive gas, vapors or dust are present. Operating shock is 15 g peak for 11 ms, and vibration is 1 g peak from 5…2000 Hz. Altitude is limited to 1000 m without derating.

For maintenance, inspect the fan and heatsink airflow periodically and verify terminal torque at commissioning. Because the drive is active in the official product data, no lifecycle restriction applies. Please verify current lifecycle status and availability with AutoDCSTech before ordering.
