DMT-6-15

Overview

The Signal Transformer DMT-6-15 is a laminated core power transformer designed for chassis mounting. It features dual primary windings rated for 115V and 230V AC input. The unit provides two secondary outputs: 5V at 1.75A and 15V at 175mA, delivering a total power rating of 6VA. Key electrical specifications include a 2500V isolation voltage and Class II certification. Physical dimensions are 82.6mm in length, 31.8mm in width, and 49.2mm in height.

Feature Summary

• Dual primary winding configuration supports both 115V and 230V AC line voltages.
• Provides split secondary outputs for simultaneous 5V and 15V DC regulation applications.
• Class II certified construction ensures compliance with safety standards for isolated circuits.

Applications

• Regulated power supplies requiring ±12 VDC or ±15 VDC rails
• Industrial control systems utilizing chassis-mounted transformers
• Electronic equipment needing isolated 5V logic and 15V analog power

Procurement Notes

Verify the specific ordering suffix to confirm exact pinout configuration and lead frame material. Ensure the procurement documentation explicitly references UL and CSA certifications for the intended market compliance. Confirm that the chassis mount style matches the mechanical constraints of the target enclosure design before finalizing the order.

Selection Notes

Select this component when a compact 6VA laminated transformer is required for chassis installation. It is suitable for designs needing separate 5V and 15V secondary rails from a single magnetic component. Consider the physical footprint of 82.6mm x 31.8mm x 49.2mm during PCB layout and enclosure planning to ensure adequate clearance for thermal dissipation and mounting hardware.

Part Context

The DMT-6-15 belongs to the DMT series of split bobbin power transformers manufactured by Signal Transformer. This series utilizes a laminated core construction to provide efficient magnetic coupling while maintaining low noise levels. The split bobbin design enhances inter-winding insulation capabilities, supporting the high isolation voltage required for safety-critical power supply applications.

Replacement Considerations

Direct substitutes within the same VA rating and form factor should be verified against the datasheet. Check compatibility of secondary voltage tolerances and current ratings. Ensure replacement parts maintain the same chassis mount hole pattern and overall dimensional envelope to fit existing mechanical assemblies without modification.
