FAQs
The HCU2133D7IP31 is designed for three-phase, 690 V electrical systems and is ideal for large motor drives, conveyors, presses, and automation equipment. Its floor-mount, IP31 enclosure supports retrofit or new installations in industrial plants, with compatibility to 50/60 Hz power networks and standard harmonic limits per IEC 61000-3-2/3-4 and IEEE 519.
Active harmonic correction detects non-linear currents in real time and injects counter-harmonics to cancel distortion, reducing total harmonic distortion (THD). With a 133 A rating and 8.2 kW watt losses, the unit stabilizes voltage and current waveforms, improving drive efficiency, reducing heat, and supporting compliant operation per relevant standards.
Yes. The floor-mount design and IP31 enclosure simplify installation in existing plants, minimizing space requirements and permitting straightforward integration with current motor drives and power distribution. Properly sized for large automation loads, it can be deployed alongside existing harmonic management strategies to upgrade power quality without major civil works.
The unit complies with IEC 61000-3-2, IEC 61000-3-4, IEEE Std. 519, UL 508C, and CSA C22.2 No. 14. These certifications validate electrical compatibility and safety performance, facilitating regulatory audits, warranty coverage, and acceptance in regulated industries such as manufacturing, data centers, and process automation.
ROI is driven by energy efficiency gains, reduced equipment wear, and fewer unplanned outages from improved power quality. The HCU2133D7IP31 requires minimal routine maintenance beyond standard periodic inspections, while delivering longer drive life and lower risk of thermal faults—beneficial for uptime-sensitive automation and total cost of ownership (TCO) reductions.
