ST-2-24

Power Transformers Overview

The ST-2-24 is a laminated core power transformer from the ST series, designed for through-hole mounting. It features a primary voltage rating of 115 VAC and operates at frequencies of 50 Hz or 60 Hz. The unit provides dual secondary windings with parallel and series configurations, delivering 12V and 24V outputs respectively. Current ratings are specified as 90mA in parallel and 45mA in series. The device has an insulation rating of 2500Vrms and a power capacity of 1.1VA.

Power Transformers Feature Summary

• Dual secondary winding configuration supporting versatile voltage output options
• Laminated core construction for standard power transformation applications
• Through-hole mounting style for board integration

Power Transformers Applications

• General purpose AC to DC power supply circuits
• Industrial control systems requiring isolated power sources
• Electronic equipment utilizing Class 2 transformer standards

Power Transformers Procurement Notes

Verify the specific datasheet version when ordering, as manufacturing specifications may evolve. Confirm that the required current ratings align with the parallel or series secondary configuration needed for your circuit design. Ensure the PCB footprint matches the through-hole pin arrangement defined in the official mechanical drawings. Cross-reference the part number with authorized distributors to ensure authenticity and traceability.

Power Transformers Selection Notes

Choose this component when a 1.1VA isolation barrier is sufficient for low-power loads. Select the parallel configuration for higher current availability at lower voltage, or the series setup for increased voltage output. Verify that the 115V primary input matches the available line voltage. Consider the physical size constraints of the enclosure relative to the transformer's dimensions.

Power Transformers Part Context

This model belongs to the ST series of power transformers manufactured by Signal Transformer. These units are characterized by their split bobbin design, which aids in electrical isolation between windings. The series is widely used in applications requiring reliable, compact, and cost-effective power conversion for low-voltage electronics.

Power Transformers Replacement Considerations

Direct substitutes within the same series include the DST-2-24, which shares similar electrical characteristics but may differ in physical packaging or isolation enhancements. Always verify pin compatibility and thermal performance before swapping components.
