ST-4-48

Power Transformers Overview

The ST-4-48 is a laminated core power transformer designed for through-hole mounting. It features a primary voltage rating of 115V AC with parallel configuration. The secondary output provides dual ratings: 24V at 250mA and 48V center-tapped at 125mA, both in parallel series configurations. The unit has a power capacity of 6VA and utilizes PC pin termination style. This component is classified as a Class 2 transformer and complies with RoHS standards.

Power Transformers Feature Summary

• Dual cavity platform design for signal transformers
• Laminated core construction for efficient power transfer
• Through-hole mounting with PC pin termination
• Class 2 safety classification

Power Transformers Applications

• General purpose power supply circuits
• Industrial control systems requiring isolated power
• Electronic equipment needing Class 2 isolation

Power Transformers Procurement Notes

Verify the specific ordering suffix to ensure correct packaging and lead time requirements. Confirm that the 115V primary input matches your system voltage. Ensure PCB layout accommodates the through-hole PC pin spacing. Check for any specific environmental certifications required by your application before finalizing the purchase order.

Power Transformers Selection Notes

Select this model when a 6VA laminated core transformer is needed for 115VAC primary applications. The dual secondary outputs (24V/250mA and 48V/125mA) allow for flexible power distribution. Consider the physical size constraints of the through-hole package. Verify that the Class 2 rating meets the safety isolation requirements of the end product.

Power Transformers Part Context

This component belongs to the Signal Transformer ST series, which utilizes a dual cavity platform. The series includes variants like DST-4-48 and ST-5-48. These transformers are designed for high-frequency and surface mount or through-hole applications depending on the specific suffix. The ST series focuses on reliable power conversion for industrial and commercial electronics.

Power Transformers Replacement Considerations

The DST-4-48 is a related variant within the same series. Verify compatibility regarding mounting style and exact electrical parameters before substitution. Ensure the replacement maintains the same Class 2 safety rating and lamination type.
