E050WB

Overview

The SolaHD E050WB is an encapsulated industrial control auxiliary transformer from the SBE Series. It features a 0.05 kVA (50 VA) power rating and operates at 50/60 Hz. The primary voltage supports 240 V and 480 V AC, while the secondary output provides 120 V AC. The unit utilizes wire lead connections and is designed for chassis mounting. Key safety components include a pre-installed primary fuse block compliant with Class CC standards and a built-in midget-type secondary fuse. The device includes a finger-safe cover and is constructed with 105-degree insulation class materials.

Feature Summary

• Encapsulated industrial control auxiliary transformer design
• Integrated primary Class CC fuse block and secondary midget-type fuse
• Finger-safe cover for enhanced operator protection
• Chassis mount configuration with wire lead connections

Applications

• Industrial control panel auxiliary power supply
• Machine tool control circuit isolation
• Safety interlock system power distribution
• Factory automation equipment control logic

Procurement Notes

Verify that the specific order matches the E050WB part number to ensure inclusion of the Class CC primary fuse block and midget secondary fuse. Confirm that the application requires the specified 240/480 VAC primary and 120 VAC secondary voltages. Check physical dimensions against available chassis space, as this model uses wire leads rather than PCB pins. Ensure the installation environment supports the required 105-degree insulation class temperature rating.

Selection Notes

Select the E050WB when an encapsulated, finger-safe control transformer is required for industrial environments. This model is suitable for applications needing integrated fusing on both primary and secondary sides without external components. Consider this part if chassis mounting and wire lead termination are preferred over plug-in or PCB options. Verify that the 50 VA capacity meets the load requirements of the control circuitry.

Part Context

The E050WB belongs to the SolaHD SBE Series of encapsulated industrial control transformers. This series is characterized by compact designs integrating safety features such as finger-safe covers and internal fusing. These units are engineered for durability in harsh industrial settings, providing reliable isolation and voltage transformation for control circuits while minimizing the need for additional protective hardware.

Replacement Considerations

Direct replacement requires verifying identical electrical ratings: 50 VA, 240/480 VAC primary, 120 VAC secondary, and 50/60 Hz frequency. Ensure the substitute component also offers encapsulation, Class CC primary fusing, and midget secondary fusing. Physical compatibility must be confirmed, specifically regarding chassis mounting holes and wire lead length. Generic control transformers lacking integrated fusing or finger-safe covers are not suitable replacements.
