E050D

Overview

The SolaHD E050D is a 50 VA industrial control transformer from the SBE series, featuring an epoxy-encapsulated laminated core and interleaved copper windings. It operates at 60 Hz with a primary voltage rating of 240V or 480V and provides a 24V secondary output. Designed for chassis or panel mounting, it measures approximately 3.01 inches in width, 3.99 inches in depth, and 2.72 inches in height. The unit holds UL 506, CSA C22.2, and NEMA ST-1 approvals.

Feature Summary

• Epoxy encapsulation seals windings against moisture, dirt, and industrial contaminants
• Interleaved copper windings reduce I2R losses to maximize operational efficiency
• Laminated core construction supports standard industrial control frequencies

Applications

• Industrial control panels requiring isolated power supplies
• Machine tool electrical systems needing step-down voltage conversion
• Automation equipment utilizing 24VAC control circuits

Procurement Notes

Verify that the specific order matches the E050D part number to ensure correct voltage configuration (240/480V primary to 24V secondary). Confirm physical mounting requirements align with the specified chassis or panel dimensions. Check for required safety certifications such as UL 506 or CSA C22.2 based on regional compliance standards before finalizing procurement.

Selection Notes

Select this model when a 50 VA capacity is sufficient for the load. Ensure the input voltage matches either 240V or 480V single-phase sources. Consider the epoxy encapsulation for environments with high humidity or particulate exposure. Verify that the 24VAC secondary output meets the control circuit requirements without exceeding thermal limits.

Part Context

The E050D belongs to the SolaHD SBE series of encapsulated control transformers. This series is designed for durability in harsh industrial settings. The component serves as a critical interface for stepping down line voltage to safer control levels. It replaces older open-frame designs where environmental protection was previously lacking.

Replacement Considerations

Direct substitutes must match the 50 VA rating, 240/480V to 24VAC ratio, and encapsulated form factor. Verify dimensional compatibility for existing panel cutouts. Cross-reference safety listings to ensure equivalent regulatory approval status.
