The Allen-Bradley 22C-B049A103 is a PowerFlex 400 module with an input voltage of 240V AC. It is used for fan and pump applications, a horsepower output of 15 HP, and 3-phase input power. The drive has an IP30 / NEMA/UL Type 1 enclosure and amperage of 49 Amps. The 22C-B049A103 provides users with an easy setup in power-driven fan and pump systems. The drive provides a wide variety of built-in features permitting for unified system integration. The 22C-B049A103 is a worthwhile solution for speed regulation in adjustable torque fan and pump applications.

The 22C-B049A103 has an input which can be connected to a fire regulator board or else to other fire/life protection systems, allowing regulation of the drive to be superseded. A purge response will start the drive at a programmable purge speed irrespective of the chosen start source. The purge can happen and is active at any time whether the drive is stopped or running. Command by purge will take precedence over a halt command from the network/comm port and over an SW Enable command from the terminal block. The 22C-B049A103 can be integrated into fire alarm arrangements or interconnected using cooling coils via a function loss response on the drive. The drive will immediately coast to a halt if functioning and issue an error upon the opening of the input. The drive will only be permitted to resume operation as soon as the alarm state is cleared and the drive error is reset.

The 22C-B049A103 is part of the PowerFlex 400 product category that is manufactured by Allen-Bradley. Being part of the PowerFlex 400 series, the standard features of the drive includes embedded Input and Output channels that is comprised of Seven (7) Sink / Source discrete inputs, One (1) Open Output; Two (2) Form C Contacts for Discrete outputs, Two (2) Analog Input 0-10VDC; 0-20mA analog inputs and Two (2) Analog Input 0-10VDC; 0-20mA. It also come with an embedded Keypad for user interface and LCD readout which display Two (2) lines of 16-Character readouts per line. It also has an integral RS485 communication port allowing configuration and operation via a daisy-chain network.

The 22C-B049A103 has an input voltage supply requirement of 180-265VAC, 3-Phase along an input current and frequencies of 51 A and 48-63 Hz, respectively. It delivers a continuous output current amounting to 49 Amperes, applicable for motors rated 15.0 HP (11.0 KW).

Aside from the Volts / Hertz control method, the drive is also equipped with Slip compensation functionality as well as capable of implementing Proportional + Derivative + Integral (PID) control method. This PID algorithm allows the drive to function as a controller itself, capable of automatically control the required speed output with reference to the input process variable.
