E750WB

Overview

The SolaHD E750WB is a 750VA encapsulated midget control transformer designed for industrial applications. It features a primary voltage rating of 240/480VAC and provides secondary outputs of 120VAC at 50/60 Hz. The unit utilizes epoxy encapsulation to seal windings against moisture, dirt, and industrial contaminants. Key structural components include interleaved copper windings to reduce I2R losses and a finger-safe cover for enhanced operator protection. The device incorporates a pre-installed primary fuse block compliant with Class CC standards and includes built-in midget-type secondary fuses. It supports panel mounting configurations.

Feature Summary

• Epoxy encapsulation seals windings from moisture, dirt, and industrial contaminants
• Interleaved copper windings reduce I2R losses for improved efficiency
• Integrated primary Class CC fuse block and built-in midget-type secondary fuses
• Finger-safe cover design ensures operator protection during operation

Applications

• Industrial control panels requiring auxiliary power
• Manufacturing plant automation systems
• Process control equipment needing reliable isolated power

Procurement Notes

Verify the specific part number suffix matches the required primary voltage configuration (240/480VAC) and secondary output (120VAC). Confirm that the encapsulated housing style and integrated fuse blocks align with the system's safety and space constraints. Ensure compatibility with existing panel mounting hardware and verify that the Class CC primary fuse requirement meets local electrical codes.

Selection Notes

Select this model when a compact, encapsulated control transformer is needed for harsh environments. The 750VA rating suits moderate load requirements in automation circuits. The integrated fusing simplifies bill of materials by eliminating external fuse holders. Verify that the 240/480VAC primary input matches the available supply voltage before procurement.

Part Context

This component belongs to the SBE Encapsulated series of industrial control transformers manufactured by SolaHD. The series is characterized by its robust epoxy sealing and compact form factor, distinguishing it from open-frame or general-purpose transformers. It serves as an auxiliary power source within larger electrical assemblies where reliability and environmental resistance are prioritized over variable voltage adjustment.

Replacement Considerations

Public confirmed substitute part numbers are not provided in the available documentation. When replacing this unit, ensure the new component matches the 750VA power rating, 240/480VAC primary input, 120VAC secondary output, and physical mounting dimensions. Verify that any alternative also includes equivalent integrated fusing capabilities.
