E250JN

Overview

The SolaHD E250JN is a 250 VA industrial control transformer from the SBE series. It features an epoxy-encapsulated, copper-wound laminated core design for chassis mounting. The unit supports multi-voltage primary inputs of 208/240/480/600 VAC and 200/230/460/575 VAC, with secondary outputs of 120/24 VAC or 115/23 VAC. Rated for 60 Hz frequency, it operates within a temperature range of 0°C to +105°C. Dimensions are 5.25 inches width by 5.07 inches depth by 4.53 inches height. It holds UL 5085, UL (Canada and US), and CSA C22.2 approvals.

Feature Summary

• Epoxy encapsulation seals windings against moisture, dirt, and industrial contaminants
• Multi-voltage primary configuration supports various standard input levels
• Chassis mount design facilitates integration into control panels

Applications

• Industrial control panel power distribution
• Machine tool voltage step-down applications
• Enclosed equipment requiring isolated control power

Procurement Notes

Verify that the required secondary voltage matches the specific variant available, as the model designation may imply a default output configuration. Confirm physical mounting constraints align with the specified chassis dimensions. Ensure the operating environment temperature remains within the 0°C to +105°C range to maintain performance and safety compliance under UL and CSA standards.

Selection Notes

Select this component when a robust, encapsulated transformer is needed for harsh industrial environments. The multi-voltage primary capability allows flexibility in system design without requiring multiple part numbers for different line voltages. Verify that the 250 VA rating adequately supports the connected control circuit loads while accounting for inrush currents typical in relay and contactor applications.

Part Context

This unit belongs to the SolaHD SBE series of encapsulated industrial control transformers. These units are designed to provide reliable isolation and voltage transformation in demanding settings. The epoxy potting process distinguishes them from open-frame alternatives, offering enhanced protection against environmental factors common in manufacturing and processing facilities.

Replacement Considerations

Direct replacements must match the 250 VA rating, primary voltage options, and secondary output requirements. Verify that substitute models offer equivalent encapsulation and dimensional compatibility for existing chassis mounts. Ensure new parts hold current UL and CSA certifications for direct interchangeability in regulated installations.
