The 20F11NC104JA0NNNNN belongs to the PowerFlex 753 family of high-performance, modular AC drives aimed at general-purpose and process applications. It is a 400 V class, 3‑phase variable speed drive rated 104 A output current, providing 55 kW normal duty (ND) and 45 kW heavy duty (HD) motor power at 400–415 V, in Frame 5 mechanical size. The drive is air‑cooled with forced ventilation and has an IP20 (open-type) enclosure, intended for mounting inside an electrical panel or enclosure.
This variant is a PowerFlex 753 AC packaged drive with embedded I/O, meaning it includes built-in discrete and analog I/O for local control and monitoring without requiring external option cards for basic interfacing. The code indicates an AC input with DC terminals and precharge, integrated dynamic braking (DB) transistor, and a filtered input with common-mode jumper installed, simplifying compliance with EMC requirements and enabling direct connection of an external brake resistor for high-inertia loads or rapid deceleration.
Electrically, the drive accepts a 3‑phase nominal input around 400–415 V AC and delivers a matching 400 V class output suitable for IEC motors, with a nominal output power of 55 kW at normal duty and 45 kW at heavy duty service factor. It is designed for use with standard 50/60 Hz supplies and variable frequency output for motor speed control across a wide range, with built-in PID control and advanced protective functions including overcurrent, overvoltage, undervoltage, ground fault, and motor thermal protection.
The drive integrates into Rockwell Automation architectures using standard control interfaces and can be further expanded with option modules (communication, feedback, safety) as required by the application. This specific catalog number ships without a Human Interface Module (HIM) on the front (blank cover), but a separate HIM can be plugged in or remote-mounted if needed. Typical applications include pumps, fans, compressors, conveyors, and general-purpose machinery in OEM and plant environments requiring a robust 400 V, 55 kW-class drive.
