K20E2H150S

Power Transformers Overview

The SolaHD K20E2H150S is a 150 kVA three-phase power transformer with a K-20 rating, designed for ventilated distribution applications. It features a 480V primary input and provides dual secondary voltages of 208Y/120V. The unit utilizes a laminated core construction with multiple taps on both primary and secondary windings to accommodate voltage variations. Rated for DOE 2016 compliance, it supports heavy harmonic loads typical in commercial and industrial settings.

Power Transformers Feature Summary

• K-20 rated design specifically engineered to withstand non-linear load harmonics without overheating
• Ventilated construction allows for efficient heat dissipation in enclosed or panel installations
• DOE 2016 compliant efficiency standards ensure reduced energy loss during operation
• Multiple tap configurations on primary and secondary windings provide flexible voltage adjustment

Power Transformers Applications

• Powering variable frequency drives (VFDs) and other non-linear electronic loads
• Industrial control panels requiring stable voltage under harmonic distortion conditions
• Commercial building electrical distribution systems with significant computer equipment loads

Power Transformers Procurement Notes

Verify the specific voltage configuration and tap requirements against the application schematic before ordering. Confirm that the installation environment meets the ventilation requirements specified for this ventilated model. Ensure the mounting infrastructure supports the physical dimensions and weight of the 150 kVA unit. Check for any regional regulatory certifications required for the final deployment site.

Power Transformers Selection Notes

Select this model when the load profile includes high harmonic content exceeding standard K-4 or K-9 ratings. The 150 kVA capacity suits large-scale commercial or light industrial distribution needs. Consider the ventilated design constraints if space limitations restrict airflow around the transformer enclosure. Verify that the 480V primary supply matches the available facility power source.

Power Transformers Part Context

This component belongs to the SolaHD K-Factor series of transformers, which are specialized for handling harmonic-rich currents. The K-20 rating indicates a higher thermal capacity compared to standard distribution transformers. It is part of the broader EE2 product line focused on robust performance in demanding electrical environments.

Power Transformers Replacement Considerations

Direct replacements must match the 150 kVA rating, K-20 classification, and 480V-to-208Y/120V transformation ratio. Verify that substitute models also meet DOE 2016 efficiency standards. Ensure physical mounting dimensions and terminal configurations are compatible with existing infrastructure.
