E500EW

Overview

The SolaHD E500EW is a 500 VA industrial control transformer from the SBE Series. It features dual primary windings rated for 240 V and 480 V, providing a single secondary output of 120 V. The unit utilizes encapsulated copper windings on a laminated core to protect against moisture and dirt. Designed for bracket mounting, it includes factory-installed Class CC primary fuse holders and midget-type secondary fuses. Operating at 60 Hz, the transformer supports a temperature range of 0 C to +105 C with wire lead terminations.

Feature Summary

• Epoxy encapsulation protects internal components from environmental contaminants
• Factory-installed primary and secondary fuse protection systems
• Dual primary winding configuration for versatile voltage input compatibility

Applications

• Industrial control panel power distribution
• Machine tool electrical system isolation
• Automation equipment auxiliary power supply

Procurement Notes

Verify that the specific order matches the E500EW model designation rather than similar variants like E500WA or ELW500E. Confirm the requirement for integrated fuse holders, as some series members may lack this feature. Ensure the application voltage aligns with the 240/480 V primary rating. Check datasheet specifications for exact physical dimensions and weight to confirm fit within the intended enclosure space.

Selection Notes

Select this component when a 500 VA capacity is required for isolating control circuits from main power lines. The encapsulated construction makes it suitable for harsh industrial environments where dust or moisture resistance is necessary. Choose this model if pre-wired fuse protection is preferred over field installation. Verify that the bracket mount style fits the available panel space compared to chassis mount alternatives.

Part Context

This transformer belongs to the SolaHD SBE Series, which specializes in encapsulated copper-wound industrial control transformers. The series is designed to provide reliable isolation and voltage transformation for heavy-duty applications. The E500EW variant specifically integrates protective fuse elements directly into the assembly, simplifying installation and ensuring compliance with safety standards for industrial control equipment.

Replacement Considerations

Direct substitutes include other SolaHD models within the same SBE series offering identical 500 VA ratings and encapsulated construction. Verify that any replacement maintains the dual primary voltage configuration and integrated fuse holder requirements. Cross-reference physical dimensions and mounting hole patterns to ensure mechanical compatibility without modifying existing panel structures.
