Overview
The SolaHD E250EWA is a 250 VA encapsulated industrial control transformer featuring copper windings and an IP20 touch-proof design. It operates at 50/60 Hz with UL and CSA approvals under ANSI/NEMA ST-1 standards. The unit measures 4.5 inches in width, 5.21 inches in depth, and 5.36 inches in height. Electrical configuration includes a 120/240 V AC primary and a 24 VAC secondary output. The model designation indicates factory wiring with FBPC1 and FB2 components integrated.
Feature Summary
- Encapsulated epoxy construction seals windings against moisture and dirt for enhanced durability
- IP20 touch-proof terminations ensure operator safety during installation and maintenance
- Extra deep molded barriers minimize the risk of electrical failures in rugged environments
Applications
- Industrial control panels requiring isolated power sources
- Machinery protection circuits demanding reliable voltage transformation
- Facility automation systems operating in harsh environmental conditions
Procurement Notes
Verify the specific ordering suffix to confirm factory-wired configurations such as FBPC1 and FB2 are included as required by the system design. Confirm that the 24 VAC secondary output aligns with downstream control device specifications. Ensure the chassis mount form factor fits within the designated enclosure dimensions. Cross-reference the UL and CSA approval marks with local regulatory requirements for the installation site.
Selection Notes
Select this component when a robust, encapsulated transformer is needed for industrial control applications. The 250 VA rating supports moderate load requirements while maintaining efficiency. The 120/240 V AC primary input provides flexibility for various supply voltages. Consider the physical dimensions and chassis mounting style for integration into existing panel layouts. Verify frequency compatibility with the incoming power source.
Part Context
This part belongs to the SBE series of encapsulated industrial control transformers from SolaHD. The series is characterized by copper windings and epoxy encapsulation designed for reliability. The E250EWA variant specifically integrates factory wiring options to simplify installation. It serves as a standard solution for stepping down line voltage to lower control voltages in industrial settings.
Replacement Considerations
Direct substitutes must match the 250 VA power rating, 24 VAC secondary output, and 120/240 V AC primary input. Encapsulation type and IP20 safety ratings should be comparable. Verify dimensional compatibility for chassis mounting. Check for equivalent UL and CSA certifications to ensure regulatory compliance in the target market.
