Overview
The Signal Transformer DST-7-16 is a laminated core power transformer designed for through-hole mounting. It features dual primary windings rated for 115 VAC and 230 VAC parallel operation, and dual secondary windings providing 8V at 4.5A in parallel or 16V at 2.25A in series. The unit has a maximum power rating of 36 VA and operates at 50/60 Hz. Physical dimensions are 66.7 mm length, 55.5 mm width, and 40.4 mm height, with a weight of 499 g. It offers 2500 Vrms isolation voltage and complies with Class 2 safety standards.
Feature Summary
- Split bobbin construction for enhanced electrical isolation
- Dual primary and secondary winding configurations for flexible input/output options
- Laminated core design for efficient power transfer
- Class 2 transformer classification for safety compliance
Applications
- Industrial control panels requiring isolated power supplies
- General purpose equipment needing 16V or 8V AC outputs
- Audio and instrumentation systems utilizing split-bobbin isolation
- Low-voltage AC power distribution in commercial machinery
Procurement Notes
Verify the specific datasheet version to confirm RoHS compliance status and any recent manufacturing changes. Ensure the ordering suffix matches the required pin configuration and insulation class. Cross-reference the physical footprint against PCB layout constraints before finalizing procurement decisions.
Selection Notes
Select this model when dual voltage inputs (115V/230V) and split secondary outputs (8V/16V) are required in a single component. The 36 VA rating supports moderate load currents. Consider the through-hole mounting style and physical dimensions for enclosure integration. Verify that the 2500 Vrms isolation meets system safety requirements.
Part Context
The DST-7-16 belongs to the Split/Tran™ DST series by Signal Transformer. This series utilizes split bobbin technology to improve isolation performance between windings. The product line is designed for general-purpose power transformation applications where high reliability and compact form factors are prioritized.
Replacement Considerations
No public confirmed substitute part numbers are available in the provided documentation. Consult manufacturer guidelines for cross-referencing alternatives based on specific electrical and mechanical constraints.
