DP-241-7-120

Overview

The DP-241-7-120 is a laminated core power transformer from the Two-4-One series by Signal Transformer. It features dual primary windings rated for 115 VAC and 230 VAC operation at 50 Hz or 60 Hz frequencies. The single secondary winding provides a center-tapped output of 120 VCT with a maximum current rating of 500 mA. With a power capacity of 56 VA, it utilizes quick connect terminals for chassis mounting. The unit measures 82.6 mm in length, 44.3 mm in width, and 49.8 mm in height, weighing approximately 500 g.

Feature Summary

• Dual primary winding configuration enables flexible voltage selection between 115 VAC and 230 VAC inputs.
• Center-tapped secondary design supports split-phase applications requiring balanced high-voltage outputs.
• Chassis mount construction ensures secure installation within industrial control enclosures.

Applications

• Industrial control systems requiring isolated power supply
• Equipment utilizing split-phase rectifier circuits
• High-voltage power stages in instrumentation

Procurement Notes

Verify that the specific part number matches the required electrical specifications, particularly the 56 VA rating and 120 VCT secondary output. Confirm terminal type compatibility with existing wiring harnesses, as this model uses quick connects. Ensure the chassis mounting dimensions align with the designated enclosure space. Check RoHS compliance status if environmental regulations apply to the final assembly.

Selection Notes

Select this component when a robust laminated core transformer is needed for 50/60 Hz applications. The dual primary feature simplifies inventory management for global deployments by accommodating different line voltages. Consider the physical size and weight constraints, as the chassis mount style requires adequate panel support. Verify insulation requirements against the 2500Vrms isolation standard provided by this series.

Part Context

This transformer belongs to the Two-4-One series, designed for industrial environments. It replaces older designs by offering standardized dimensions and electrical ratings across multiple variants. The series emphasizes reliability through laminated core construction and barrier strip options in related models.

Replacement Considerations

Direct substitutes include other 56 VA transformers with identical 120 VCT secondary outputs and dual primary configurations. Ensure replacement units maintain the same chassis mounting footprint and quick connect terminal spacing to avoid mechanical modifications.
