FAQs
Confirm the system is three-phase with 380-480V nominal voltage and 50/60 Hz. Check available floor mounting space, ensure top or bottom cable entry compatibility, and verify nearby enclosure clearance for the 61.1 inch height. Confirm electrical clearances per local codes, and verify busbar and circuit protection coordination with existing protection relays.
The HCU2120D5IP31 implements active harmonic correction to mitigate low-order harmonics, aligning with IEC 61000-3-2/3-4 limits andIEEE 519 recommendations. It reduces total harmonic distortion, stabilizes voltage waveform, and helps keep individual harmonic currents within permitted levels, supporting safer operation of sensitive drives and controls.
Yes. In data centers, it improves power quality for critical IT equipment; in manufacturing lines, it protects drives and motors from harmonic-induced stress. With 120A capacity and 380-480V three-phase support, it is well-suited for mid-to-large facility deployments where harmonics significantly impact efficiency and uptime.
The unit measures 21.2 inches in depth, 61.1 inches in height, and 22.8 inches in width, with a weight of 248.5 pounds. Ensure a flat, level mounting surface, adequate anchoring, and sufficient access for maintenance. Plan cable routing for top or bottom entry, and allocate space for cooling and service clearances around the cabinet.
Schedule periodic checks of harmonic settings, monitor energy losses (2.8 kW watt losses reflect continuous losses to be managed), and verify cooling performance to prevent thermal degradation. The unit’s compliance with key standards reduces risk and enables predictable performance, shortening project lead times and lowering long-term operating costs.
