HS1F750B

Overview

The SolaHD HS1F1750B is a non-ventilated, encapsulated automation transformer with a 0.75 kVA rating. It features a laminated core and chassis mount design. The primary voltage options are 240V or 480V, while the secondary output provides 120V or 240V at 6.25A. Operating at 60 Hz, this single-phase unit utilizes UL Class 200 C insulation for high-temperature durability. It includes electrostatic shielding to enhance power quality and is constructed for heavy-duty applications in hazardous locations.

Feature Summary

• Encapsulated construction designed for harsh environments
• Electrostatic shielding for enhanced power quality
• UL Class 200 C insulation for high temperature durability
• Capable of connection as an autotransformer

Applications

• Hazardous locations (Class 1, Division 2, Group A-D)
• Automation systems requiring isolated power
• Industrial control panels needing voltage conversion
• Heavy-duty equipment in demanding operational settings

Procurement Notes

Verify that the specific order matches the required primary and secondary voltage configurations, as the HS1F1750B supports multiple input/output combinations. Confirm that the chassis mounting style aligns with the installation space constraints. Ensure the application environment does not exceed the specified temperature ratings associated with the Class 200 C insulation system.

Selection Notes

Select this model when a compact, encapsulated transformer is needed for hazardous area compliance. The dual primary voltage capability allows flexibility for different supply networks. Consider the physical dimensions and chassis mount requirement during mechanical integration. This unit is suitable where low noise and high reliability are prioritized over active cooling methods.

Part Context

This component belongs to the SolaHD Automation Transformer series, manufactured by Emerson under the Sola/Hevi-Duty brand. These transformers are engineered for robust performance in industrial settings. The HS1F1750B specifically addresses needs for isolated power supplies in confined or hazardous spaces where ventilation is restricted or prohibited.

Replacement Considerations

Direct substitutes must match the 0.75 kVA rating, encapsulated type, and compatible voltage inputs/outputs. Verify that any replacement maintains the same hazardous location classification and chassis mounting footprint to ensure seamless integration without mechanical modifications.
