High-capacity 157A active harmonic correction unit engineered for heavy three-phase loads, the HCU2 delivers targeted harmonic mitigation with a measured watt loss of 7.2 kW. By actively shaping current draw, it supports power quality improvements that translate directly into reduced heating, longer motor life, and improved reliability in drives-heavy lines. Active harmonic correction technology is designed to counter nonlinear loads, such as variable frequency drives and welders, in real time. The business impact is a lower total harmonic distortion (THD), better power factor, and fewer unplanned outages, which is crucial for uptime and utility penalties. Compliance and certifications provide a clear path to regulation-ready installations, with IEC 61000-3-2/3-4, IEEE Std. 519, UL 508C, and CSA C22.2 No. 14, reducing regulatory risk and streamlining audits. Rugged IP31 enclosure and floor-mount design simplify installation and retrofit projects, offering stable operation and straightforward service access in demanding environments. Operational versatility covers 50/60 Hz and a 600 V rating for three-phase systems, making it broadly compatible with industrial power networks while informing accurate panel planning. From a practical perspective, customers gain energy savings, reduced harmonic penalties, and improved drive/transfomer life, translating into lower maintenance costs and faster payback on modernization projects.

FAQs
The HCU2157D6IP31 is designed for floor mounting in an IP31 enclosure, suitable for industrial control rooms and electrical spaces. Plan for a dedicated space with adequate clearance for service access, ensure support for the substantial footprint (61.12 in L, 88.32 in H, 29.62 in W) and a 1737 lb weight, and verify 50/60 Hz, 600 V three-phase connections are available.
The unit uses active harmonic correction to counter nonlinear loads such as VFDs and CNCs in real time, reducing total harmonic distortion (THD) and improving power factor. This translates to fewer voltage stress events, reduced heat, and enhanced reliability across drive-heavy processes, contributing to lower energy penalties and better equipment longevity.
Yes. The HCU2157D6IP31 is rated for 50/60 Hz operation and a 600 V voltage rating, making it compatible with a wide range of three-phase industrial power systems. This flexibility supports multi-site deployments and simplifies standardization efforts across facilities with varying electrical standards.
The unit complies with IEC 61000-3-2 and IEC 61000-3-4, IEEE Std. 519, UL 508C, and CSA C22.2 No. 14. These certifications help ensure regulatory alignment, reduce compliance risk during audits, and simplify procurement for regulated environments or supplier qualification processes.
By reducing harmonic penalties, improving energy efficiency, and extending component life, the HCU2 typically delivers a favorable return on investment through lower utility costs and reduced maintenance on drives and transformers. Additionally, the solution minimizes unplanned outages, supporting steadier production schedules and reduced downtime.
