DMT-8-15

Overview

The DMT-8-15 is a laminated core power transformer manufactured by Signal Transformer, designed for chassis mounting applications. It features a dual primary voltage rating of 115V and 230V to accommodate various input standards. The unit provides two secondary outputs: a 5V winding rated at 4A and a split ±15V winding rated at 500mA each. With an 8VA power rating, it supports regulated power supply designs requiring multiple voltage rails. The transformer utilizes solder lug or quick connect terminals for circuit integration.

Feature Summary

• Dual primary voltage configuration supporting both 115V and 230V inputs
• Multiple secondary outputs providing 5V and split ±15V DC rails
• Chassis mount construction with flange installation style
• Laminated core design for standard frequency operation

Applications

• Regulated power supplies requiring 5VDC output
• Electronic systems utilizing ±15VDC analog circuits
• Industrial control equipment power modules
• Test and measurement instrument power sections

Procurement Notes

Verify the specific terminal type required for your assembly, as sources indicate availability in both solder lug and quick connect configurations. Confirm that the ±15V secondary center tap matches your ground scheme. Ensure the chassis mounting holes align with the physical dimensions provided in the official datasheet before ordering.

Selection Notes

Select this component when an 8VA capacity is sufficient for the load requirements. The dual primary allows flexibility for global deployment without changing hardware. Consider the physical size constraints, as chassis mount transformers require adequate clearance for heat dissipation and mechanical stability during operation.

Part Context

This part belongs to the DMT series of laminated core transformers from Signal Transformer. These units are engineered for general-purpose power conversion in industrial and commercial electronics. The series offers standardized ratings to simplify design-in processes for engineers developing multi-rail power distribution networks.

Replacement Considerations

Direct substitutes within the same series include models with identical VA ratings and compatible secondary voltages. Verify that any replacement maintains the same chassis mounting footprint and terminal interface type to ensure mechanical compatibility without redesigning the enclosure.
