E250JL

Overview

The SolaHD E250JL is a 250VA encapsulated industrial control transformer designed for single-phase applications. It features a primary voltage rating of 208/240/277 VAC and provides secondary outputs of 120/240 VAC. The unit operates at a frequency of 60 Hz and supports a maximum operating temperature of +105°C. Physical dimensions are approximately 4.5 inches in width, 5.21 inches in depth, and 3.89 inches in height. Termination is achieved via wire leads, and the device carries UL, CSA, and NEMA ST-1 approvals.

Feature Summary

• Epoxy encapsulation seals windings against moisture, dirt, and industrial contaminants
• Multi-tap primary configuration allows compatibility with 208, 240, and 277 VAC input sources
• Dual secondary voltage options provide flexibility for 120V or 240V control circuits

Applications

• Industrial machine tool control panels
• Factory automation equipment power distribution
• HVAC system control circuit isolation
• General industrial machinery step-down voltage conversion

Procurement Notes

Verify that the incoming component matches the specific part number E250JL to ensure correct voltage ratings and physical dimensions. Confirm that the wire lead termination style aligns with your assembly requirements. Check for UL and CSA certification marks on the housing to validate compliance with safety standards. Inspect the epoxy encapsulation for any visible damage prior to installation.

Selection Notes

Select this model when a robust, encapsulated transformer is required for harsh industrial environments. Ensure the primary voltage matches the available supply (208/240/277 VAC) and the load requirements fit within the 250VA capacity. Consider the wire lead termination if direct wiring is preferred over terminal blocks. Verify that the operating temperature range meets the ambient conditions of the installation site.

Part Context

This component belongs to the SolaHD SBE series of encapsulated industrial control transformers. The series is characterized by its durable epoxy potting, which enhances longevity in demanding settings. The E250JL specifically addresses applications requiring reliable voltage transformation from standard industrial line voltages to lower control voltages.

Replacement Considerations

Direct substitutes must match the 250VA rating, 208/240/277-120/240 VAC configuration, and encapsulated construction. Verify dimensional compatibility for mounting space. Ensure equivalent thermal ratings and safety certifications (UL/CSA) are maintained for regulatory compliance.
