MPI-250-24

Power Transformers Overview

The Signal Transformer MPI-250-24 is a laminated core power transformer with a 250 VA rating. It features a single primary winding supporting 100, 115, 200, 215, and 230 VAC inputs at 50/60 Hz. The dual secondary windings provide 24 VCT or parallel 12 V outputs. Rated currents are 20.8 A in parallel or 10.4 A in series configurations. The unit measures 104.8 mm length, 104.9 mm width, and 98.2 mm height, utilizing screw terminals for chassis mounting.

Power Transformers Feature Summary

• Laminated core construction for industrial power applications
• Multi-tap primary winding for global voltage compatibility
• Dual secondary windings allowing flexible series or parallel output configurations

Power Transformers Applications

• Industrial control systems requiring isolated power
• Rectifier power supply circuits
• Equipment needing 24V or 12V DC conversion

Power Transformers Procurement Notes

Verify the specific datasheet version to confirm terminal pinout and insulation class requirements. Ensure the input voltage matches one of the supported primary ratings (100-230 VAC). Confirm that the mechanical dimensions fit the chassis enclosure space. Check for any regional compliance certifications required for the target market installation.

Power Transformers Selection Notes

Select this model when a 250 VA capacity is necessary for high-current rectifier applications. Choose the series secondary configuration for higher voltage needs or parallel for higher current. Verify that the chassis mounting style aligns with the available hardware. Consider the physical footprint constraints against the 104.8 x 104.9 mm base dimensions.

Power Transformers Part Context

This component belongs to the MPI series of conventional rectifier power transformers from Bel Signal Transformer. These units are designed for robust industrial environments where reliable isolation and voltage transformation are critical. The series typically offers various power ratings and voltage combinations to suit diverse control panel architectures.

Power Transformers Replacement Considerations

Direct substitutes include other 250 VA laminated transformers with identical 100-230 VAC primary and 24 VCT secondary specifications. Ensure replacement units match the 104.8 x 104.9 x 98.2 mm envelope and screw terminal interface. Verify equivalent thermal performance and insulation ratings before integration.
