HSP12F75AS

Overview

The SolaHD HSP12F75AS is a single-phase encapsulated automation transformer with a 7.5 kVA power rating. It operates at 60 Hz and features an epoxy-encapsulated design to seal windings against moisture. The unit supports multiple primary voltage ratings of 120 V, 208 V, 240 V, and 277 V, while providing secondary outputs of 120 V and 240 V. Constructed with copper windings, it includes IP20 touch-proof terminations for safety. The transformer is rated for hazardous locations and harsh industrial environments, ensuring rugged performance in demanding applications.

Feature Summary

• Epoxy encapsulation seals windings against moisture and environmental contaminants
• IP20 touch-proof terminations enhance operator safety
• Copper windings provide reliable electrical conductivity
• Rated for hazardous locations and harsh industrial environments

Applications

• Automation systems requiring isolated power conversion
• Industrial control panels operating in hazardous locations
• Equipment needing voltage step-down from 277 V or 240 V primary sources
• Machinery requiring protection against moisture and dust ingress

Procurement Notes

Verify the specific ordering suffix matches the required temperature rise rating, as indicated by code #HSP12F75AS for +115K rise. Confirm that the primary voltage configuration aligns with the available input options of 120/208/240/277 VAC. Ensure the application environment meets the hazardous location ratings specified for this encapsulated series. Cross-reference the physical dimensions of 355.6 mm width and 431.8 mm height with panel space constraints before finalizing procurement.

Selection Notes

Select this model when a single-phase isolation transformer is needed for 7.5 kVA loads in harsh conditions. The multi-tap primary allows flexibility for various input voltages including 277 V. The encapsulated design eliminates the need for external ventilation, making it suitable for enclosed spaces. Verify that the secondary voltage requirements match the 120/240 V output capabilities. Consider the IP20 termination safety if personnel access is possible during operation.

Part Context

This component belongs to the SolaHD Automation Transformers series manufactured by Emerson under the Sola/Hevi-Duty brand. It is part of a line of non-ventilated transformers designed for industrial automation. The HSP series is characterized by its rugged construction and suitability for environments where standard transformers might fail due to moisture or dust exposure.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. When replacing, ensure the new unit matches the 7.5 kVA rating, single-phase configuration, and compatible voltage inputs/outputs. Verify that any alternative maintains the same hazardous location ratings and encapsulation standards.
