HS1B75

Overview

The SolaHD HS1B75 is a 0.075 kVA single-phase non-ventilated automation transformer designed for industrial machinery and OEM systems. It features a 240x480 primary voltage configuration with 120/240 secondary outputs. The unit operates at 60 Hz and utilizes an UL Class 130°C or 80°C insulation system, ensuring an 80°C temperature rise under full load. Constructed as a non-encapsulated wall-mount device, it meets UL 506, UL 1561, and CSA C22.2 standards. Its compact dimensions are 4 inches wide by 4 inches deep by 6 inches high, providing reliable voltage transformation in demanding environments.

Feature Summary

• Non-ventilated design suitable for harsh industrial environments
• UL Listed and CSA Approved for safety compliance
• Class 130°C insulation system for thermal stability
• Wall-mount construction for space-efficient installation

Applications

• Industrial machinery control circuits
• Automation equipment power distribution
• OEM system integration
• Harsh environment instrumentation

Procurement Notes

Verify the specific insulation class rating (80°C vs 130°C) required for your application before purchase. Confirm that the non-encapsulated form factor aligns with environmental protection needs, as this model lacks the rugged enclosure found in hazardous location variants. Ensure mounting hardware supports the specified physical dimensions and weight constraints for secure installation.

Selection Notes

Select the HS1B75 when a low-power, single-phase voltage step-down or isolation solution is needed for indoor or protected outdoor use. This model is appropriate where NEMA Type 3R protection is sufficient but encapsulation is not mandatory. Compare against encapsulated series if exposure to moisture or dust requires higher ingress protection levels beyond standard wall-mount capabilities.

Part Context

The HS1B75 belongs to the SolaHD Automation Transformers series, which provides non-ventilated solutions for industrial applications. This series emphasizes dependable voltage transformation and environmental protection. The product line includes both encapsulated and non-encapsulated options to address varying degrees of harshness in factory automation and inspection settings.

Replacement Considerations

Direct substitutes within the SolaHD HS1B series should be evaluated based on identical VA ratings and voltage configurations. Verify that any replacement maintains the same UL listing and physical footprint to ensure compatibility with existing mounting infrastructure and electrical connections.
