DMT-6-12

Overview

The DMT-6-12 is a laminated core power transformer manufactured by Signal Transformer, designed for chassis mounting. It features dual primary windings rated for 115 VAC and 230 VAC input at 50/60 Hz. The unit provides two secondary outputs: 5 VDC at 1.75 A and ±12 VDC (center-tapped) at 210 mA each. With a total power rating of 6 VA, it offers 2500 Vrms isolation voltage. Physical dimensions are 82.6 mm in length, 31.8 mm in width, and 49.2 mm in height.

Feature Summary

• Dual primary winding configuration supports universal AC input voltages.
• Provides split secondary outputs suitable for regulated DC power supply circuits.
• Chassis mount design with quick-connect termination style.

Applications

• Regulated power supplies requiring 5V and ±12V rails
• Industrial control equipment power stages
• Electronic test and measurement instrumentation

Procurement Notes

Verify the specific manufacturer designation, as Signal Transformer products are often distributed under Bel Fuse or Bel Power Solutions branding. Confirm that the datasheet references the correct pinout and insulation class for your enclosure requirements. Ensure compatibility with the intended chassis mounting hardware before finalizing procurement orders.

Selection Notes

Select this component when a compact, chassis-mountable transformer is needed for low-power applications requiring both single-ended and split-rail outputs. The 6 VA rating limits its use to small signal processing or logic circuits rather than high-current loads. Verify that the physical footprint fits within the available chassis space and that the lead lengths accommodate the terminal connections.

Part Context

This component belongs to the DMT series of laminated power transformers from Signal Transformer. These units are engineered for industrial and commercial applications where reliable isolation and stable voltage regulation are required. The series typically includes variants with different secondary voltage combinations to support diverse power distribution needs in electronic systems.

Replacement Considerations

Check for direct cross-references such as MT-6-12, which shares similar electrical characteristics but may differ in packaging or certification details. Ensure any substitute maintains the same 6 VA rating, 2500 Vrms isolation, and chassis mount form factor to guarantee mechanical and electrical compatibility.
