HSP5F7.5AS

Overview

The SolaHD HSP5F7.5AS is a 7.5 kVA single-phase encapsulated automation transformer designed for harsh industrial environments and hazardous locations. It features a non-ventilated construction with UL Class 180°C insulation. The unit operates at 60 Hz with a primary voltage rating of 240/480 VAC and a secondary voltage configuration of 120/240 VAC. Primary current ratings are 31.3 A at 240 V and 15.6 A at 480 V, while secondary currents are 62.5 A at 120 V and 31.3 A at 240 V. The device meets UL 506, UL 1561, and CSA C22.2 standards.

Feature Summary

• Encapsulated construction rated for hazardous locations and NEMA Type 3R protection
• Non-ventilated design suitable for confined or dusty industrial settings
• UL Class 180°C insulation system for thermal durability

Applications

• Industrial automation control systems
• Hazardous location power distribution

Procurement Notes

Verify the exact part number suffix against official Emerson Electric Co. documentation to ensure correct voltage configurations and enclosure ratings. Confirm that the specific variant matches the required primary and secondary voltage taps. Cross-reference certification marks such as UL and CSA with the intended installation jurisdiction. Ensure physical dimensions and mounting requirements align with the designated panel or wall space before finalizing procurement orders.

Selection Notes

Select this model when hazardous location compliance and encapsulation are required for single-phase power transformation. Compare primary and secondary voltage requirements against available line voltages. Consider the non-ventilated nature for environments where dust or moisture ingress is a concern. Verify that the 7.5 kVA capacity meets the load demands without exceeding thermal limits inherent to the encapsulated design.

Part Context

This component belongs to the SolaHD HS5F series of encapsulated automation transformers. The series is characterized by rugged construction for industrial use. Variants within the family share similar encapsulation technologies but differ in kVA ratings and voltage configurations. The HSP5F7.5AS represents a specific high-capacity option within this non-ventilated product line.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Direct replacement requires matching the 7.5 kVA rating, 240/480V primary, and 120/240V secondary specifications exactly. Consult manufacturer catalogs for updated series replacements if discontinuation occurs.
