Allen-Bradley 23C-D017A103NNBANN-LR Packaged PowerFlex 400 Drive Unit

Module Feature

23C-D017A103NNBANN-LR belongs to 23C series factory packaged PowerFlex400 fan & pump drive manufactured by Allen-Bradley (Rockwell Automation). The suffix -LR indicates integrated line reactor for harmonic suppression and input surge protection. Complete assembly includes PowerFlex400 VFD,fused disconnect switch,full feature bypass contactor bank,control circuit and fixed local keypad. It supports V/Hz speed regulation and built-in PID closed-loop control for pressure/flow. RS485 Modbus RTU communication onboard. Widely used in water supply pumps,HVAC fans,chiller systems and variable torque process applications.

Working principle

Three-phase AC input passes through line reactor and fused disconnect,then feeds into PowerFlex400 inverter unit. The inverter outputs variable voltage/frequency AC to regulate motor speed. When drive fault or maintenance required,bypass contactor closes to run motor directly across mains. PID function adjusts motor speed automatically to maintain set pressure or flow. Line reactor suppresses current harmonics and protects drive from voltage spikes.
