ST-7-48

Power Transformers Overview

The ST-7-48 is a laminated core power transformer from the Signal Transformer ST series, designed for through-hole mounting. It features a primary voltage rating of 115 VAC and dual secondary outputs providing 24V at 1.5A in parallel or 48V CT at 0.75A. The unit has a power rating of 36 VA and offers 2500Vrms isolation. Constructed with a split bobbin design, it supports Class 2 applications and operates within standard industrial temperature ranges.

Power Transformers Feature Summary

• Split bobbin construction for enhanced electrical isolation
• Dual secondary output configuration supporting parallel or center-tapped operation
• Laminated core design optimized for efficient power transfer

Power Transformers Applications

• Industrial control systems requiring isolated power supplies
• Equipment needing dual voltage rails from a single transformer
• Class 2 compliant low-voltage power distribution units

Power Transformers Procurement Notes

Verify the specific ordering suffix to confirm packaging type and lead time requirements. Ensure the selected variant matches the required secondary current configuration. Confirm compliance with relevant safety standards such as UL or CE before finalizing procurement orders.

Power Transformers Selection Notes

Select this model when a 36 VA capacity is required with 115V primary input. Choose between parallel 24V or center-tapped 48V secondary configurations based on load requirements. Ensure PCB layout accommodates through-hole pins and physical dimensions specified in the datasheet.

Power Transformers Part Context

Part of the ST series laminated core transformers, the ST-7-48 utilizes a split bobbin architecture to improve isolation performance. This series is widely used in general-purpose power applications where reliable voltage transformation and safety compliance are critical for system operation.

Power Transformers Replacement Considerations

The DST-7-48 is a documented substitute offering identical electrical specifications with a different casing style. Verify mechanical fit and pin compatibility before substituting.
