ST-7-10

Power Transformers Overview

The Signal Transformer ST-7-10 is a laminated core power transformer designed for through-hole mounting. It features a single primary winding rated for 115V operation at 50/60Hz frequency. The unit provides dual secondary windings configured for center-tapped output, delivering 10V CT or 5V configurations. Electrical ratings include a total power capacity of 36VA with secondary current capabilities of 3.6A and 7.2A. The device meets RoHS compliance standards and offers a dielectric strength of 2500 Vrms.

Power Transformers Feature Summary

• Laminated core construction for efficient power conversion
• Dual secondary winding design enabling flexible voltage configurations
• Through-hole mounting style for secure PCB integration
• High dielectric strength insulation for safety isolation

Power Transformers Applications

• Industrial control systems requiring isolated AC power
• Servo drive power supplies
• General purpose equipment needing 115V input step-down
• Class 2 transformer applications

Power Transformers Procurement Notes

Verify the specific datasheet version to confirm pinout orientation and physical dimensions before integration. Ensure the procurement channel is an authorized distributor to guarantee component authenticity and traceability. Check for any recent regulatory updates regarding RoHS compliance status in your target market.

Power Transformers Selection Notes

Select this model when a 36VA capacity is required from a standard 115V primary source. The dual secondary option suits designs needing both 5V and 10V rails or center-tapped rectification. Compare against the DST series if dual-primary (115V/230V) input flexibility is necessary instead of fixed 115V operation.

Power Transformers Part Context

This component belongs to the ST series of split-bobbin transformers from Signal Transformer. The series covers power ratings from 1.1VA to 36VA across various configurations. The ST-7-10 represents the higher end of this low-power range, utilizing a laminated core structure typical for general-purpose industrial power transformation.

Power Transformers Replacement Considerations

The DST-7-10 serves as a functional substitute if dual-primary voltage support (115V/230V) is required while maintaining identical secondary electrical characteristics. Verify mechanical footprint compatibility before swapping between these specific part numbers.
