E500JL

Overview

The SolaHD E500JL is a 500VA encapsulated industrial control transformer from the SBE series. It features copper windings and chassis mount construction. The primary voltage ratings are 208/240/277V, while the secondary provides 120/240V output at 60Hz. Operating temperature ranges from 0°C to +105°C. Dimensions are 5.25 inches wide by 5.75 inches deep by 4.53 inches high. It holds UL 506, CSA C22.2, NEMA ST-1 approvals and is RoHS compliant.

Feature Summary

• Epoxy encapsulation seals windings against moisture, dirt, and industrial contaminants
• Chassis mount design with laminated core for stable power conversion
• Complies with UL 506, CSA C22.2, and NEMA ST-1 standards

Applications

• Industrial control panels requiring isolated power sources
• Machine tool electrical systems
• Automation equipment power distribution
• Enclosed industrial machinery control circuits

Procurement Notes

Verify that the specific application requires the 208/240/277V primary configuration and 120/240V secondary output. Confirm chassis mounting compatibility with existing panel layouts. Ensure environmental conditions remain within the specified 0°C to +105°C operating range. Check for required certifications such as UL or CSA in the target market. Validate that the 500VA capacity meets the connected load requirements without exceeding thermal limits.

Selection Notes

Select this model when epoxy encapsulation is necessary for harsh environments. Choose based on the specific primary voltage availability (208, 240, or 277V). Consider the physical dimensions for panel space constraints. Verify that the dual secondary voltages (120/240V) match the control circuit needs. Compare against non-encapsulated alternatives if environmental protection is not required.

Part Context

The E500JL belongs to the SolaHD SBE Encapsulated Series, designed for industrial control applications. It is part of the broader Sola/Hevi-Duty product line under Emerson. This series emphasizes durability through epoxy potting, distinguishing it from open-frame transformers. It serves as a reliable component for isolating control circuits from main power lines in heavy-duty settings.

Replacement Considerations

Direct substitutes include other SolaHD SBE series models with matching VA ratings and voltage configurations. Cross-reference with equivalent encapsulated transformers from manufacturers offering UL 506 approval. Ensure replacement units maintain the same chassis mount footprint and terminal layout. Verify that any alternative matches the 60Hz frequency rating and encapsulation type.
