DST-4-36

Overview

The Signal Transformer DST-4-36 is a Class 2 laminated core power transformer designed for through-hole mounting. It features dual primary windings rated for 115 VAC and 230 VAC, and dual secondary windings providing 36 VCT/18 VAC output. The unit has a 6 VA power rating with secondary current ratings of 340 mA and 170 mA. Physical dimensions are 41.3 mm in length, with a frequency range of 50 Hz/60 Hz.

Feature Summary

• Provides superior electrical isolation with low capacitive coupling between windings
• Supports flexible input voltage configurations via dual primary winding design
• Delivers split secondary voltage outputs suitable for rectifier circuits

Applications

• Power supply units requiring Class 2 isolation
• Equipment utilizing split-phase rectification topologies
• Industrial control systems operating at 50/60 Hz

Procurement Notes

Verify the specific datasheet version to confirm exact physical tolerances and insulation class ratings. Ensure that the procurement documentation explicitly lists the 6 VA power rating and 340 mA/170 mA current specifications. Confirm compliance with relevant safety standards for Class 2 transformers before integration into final assemblies.

Selection Notes

Select this component when a compact laminated core transformer is required for 115/230 VAC input applications. The dual secondary configuration is ideal for generating positive and negative DC rails. Ensure the PCB layout accommodates the through-hole pin spacing and the 41.3 mm length constraint.

Part Context

This model belongs to the DST series of split transformers manufactured by Bel Signal Transformer. These components are engineered for general-purpose power conversion where standard isolation and moderate power delivery are necessary. The series utilizes laminated steel cores to minimize noise and improve efficiency at line frequencies.

Replacement Considerations

Cross-reference with other models in the DST series or ST series from Signal Transformer for similar voltage and power requirements. Verify that any substitute part matches the 6 VA rating and physical footprint constraints.
