K20E2H45S

Power Transformers Overview

The SolaHD K20E2H45S is a 45 kVA industrial control transformer designed for chassis mounting. It features a triple primary winding rated for 480 V and a triple secondary winding providing 120 V and 208 V outputs. The unit supports an operating frequency of 60 Hz and delivers a maximum current of 125 A on the secondary side. Physical dimensions include a length of 711 mm and a width of 559 mm. This component utilizes laminated construction for power distribution.

Power Transformers Feature Summary

• Triple primary and secondary winding configurations for flexible voltage input and output combinations
• Laminated core construction designed for robust industrial power transformation
• Chassis mounting style suitable for integration into larger electrical enclosures

Power Transformers Applications

• Industrial control systems requiring 480V to 120/208V step-down
• General purpose power distribution in manufacturing environments
• Equipment protection for sensitive production machinery

Power Transformers Procurement Notes

Verify the specific datasheet version, as part numbers may include suffixes indicating enclosure types or terminal variations. Confirm that the 480V primary rating matches your facility's supply voltage. Ensure physical clearance allows for the 711 mm length and 559 mm width during installation. Check for compliance with local electrical codes regarding chassis-mounted transformers.

Power Transformers Selection Notes

Select this model when a 45 kVA capacity is required for stepping down 480V to standard 120V or 208V control voltages. The triple winding design offers flexibility for various primary voltage inputs if needed. Consider the chassis mount requirement versus panel or wall mount options based on the available space within the equipment cabinet. Verify the 125A secondary current rating meets the load requirements.

Power Transformers Part Context

This component belongs to the SolaHD K series of industrial control transformers. These units are generally characterized by rugged construction and are intended for use in demanding industrial environments. The series typically includes models with varying kVA ratings and voltage configurations to support diverse power distribution needs across different sectors of industrial automation.

Power Transformers Replacement Considerations

Cross-reference with other SolaHD models in the K series for similar kVA ratings. Verify that any substitute maintains the 480V primary and 120/208V secondary configuration. Ensure the replacement part supports the same 60 Hz operating frequency and chassis mounting style to fit existing infrastructure without modification.
