DMT-8-12

Power Transformers Overview

The DMT-8-12 is a laminated core power transformer manufactured by Signal Transformer, designed for chassis mounting. It features a dual primary voltage rating of 115 VAC and 230 VAC at 50/60 Hz. The unit provides three secondary outputs: 5 VDC at 4 A, ±12 VDC at 600 mA each. With a total power rating of 8 VA, it utilizes a split bobbin construction. Physical dimensions are 102.4 mm in length, with a weight of approximately 1.25 kg.

Power Transformers Feature Summary

• Triple output configuration providing regulated power supply voltages
• Dual primary voltage compatibility for international operation
• Chassis mount design for secure industrial installation

Power Transformers Applications

• 5 VDC regulated power supplies
• ±12 VDC regulated power supplies
• Industrial automation control systems
• Signal conditioning equipment

Power Transformers Procurement Notes

Verify the specific datasheet version to confirm insulation ratings and regulatory certifications such as UL or CSA. Ensure the chassis mounting holes align with your enclosure specifications. Confirm that the 8 VA rating meets the total load requirements of all secondary circuits simultaneously. Check for any specific lead-free soldering process requirements if applicable to your assembly line.

Power Transformers Selection Notes

Select this component when a single transformer must provide multiple isolated DC rails from a standard AC mains input. The 8 VA rating suits low-to-medium power applications requiring stable 5 V and ±12 V outputs. Consider the physical size and chassis mount style against available panel space. Verify that the core type and frequency response match the input power source characteristics.

Power Transformers Part Context

This part belongs to the DMT series of laminated power transformers from Signal Transformer. These units are engineered for general-purpose power conversion in industrial and commercial electronics. The series offers various VA ratings and output configurations to support diverse power supply designs requiring reliable isolation and voltage transformation.

Power Transformers Replacement Considerations

Direct substitutes may include other 8 VA triple-output laminated transformers with matching pinouts and dimensions. Verify electrical equivalence for all three secondary windings. Ensure mechanical fitment matches the existing chassis mounting points. Cross-reference with manufacturer cross-reference lists for approved alternatives.
