E500EWB

Overview

The SolaHD E500EWB is a 500 VA industrial control transformer from the SBE series. It features an encapsulated laminated core design with copper windings, rated for 60 Hz operation and UL/CSA approval under ANSI/NEMA ST-1 standards. The unit includes factory-wired components: a Class CC primary fuse block (FBPC1) and built-in midget-type secondary fuses (FB2X). Dimensions are approximately 5.99 inches in height, 5.25 inches in width, and 5.75 to 6.31 inches in depth, depending on specific configuration variants.

Feature Summary

• Epoxy encapsulation seals windings against moisture, dirt, and industrial contaminants
• Factory-installed primary fuse block and built-in secondary fuses for integrated protection
• Chassis mount construction with finger-safe covers for enhanced operator safety

Applications

• Industrial control panels requiring isolated power distribution
• Machinery control circuits needing 24 VAC secondary output
• Enclosed electrical systems demanding compliance with UL and NEMA standards

Procurement Notes

Verify the exact datasheet version when ordering, as suffixes like FBPC1 and FB2X indicate specific factory wiring configurations for fusing. Confirm dimensional requirements against panel space constraints due to slight variations in depth measurements across documentation sources. Ensure compatibility with 120/240 V AC primary input voltages before integration into existing control architectures.

Selection Notes

Select this model for applications requiring robust environmental sealing via epoxy encapsulation. The integrated fusing reduces external component count but requires verification of fuse ratings against circuit load requirements. Consider chassis mounting capabilities and ensure adequate ventilation clearance around the 500 VA unit to maintain thermal performance within specified operating limits.

Part Context

This component belongs to the SolaHD SBE series of encapsulated industrial control transformers. These units are designed for harsh environments where standard open-frame transformers might fail. The E500EWB variant specifically integrates protective fusing elements directly into the assembly, distinguishing it from basic transformer models that require external protection devices.

Replacement Considerations

Direct substitutes must match the 500 VA rating, 60 Hz frequency, and encapsulated construction. Verify that replacement units include equivalent primary and secondary fusing configurations if system protection relies on these internal components. Cross-reference mounting dimensions to ensure physical fit within existing chassis enclosures.
