MPI-250-12

Power Transformers Overview

The Signal Transformer MPI-250-12 is a laminated core power transformer with a 250 VA rating. It supports primary voltages of 100, 115, 200, 215, and 230 VAC. The secondary provides 6V at 41.7A in parallel or 12V CT at 20.8A in series. It features chassis mounting, terminal block termination, and 4000Vrms isolation. Dimensions are not explicitly listed in the provided text.

Power Transformers Feature Summary

• Multi-tap primary winding configuration for global voltage compatibility
• Dual secondary output options providing flexible voltage and current delivery
• High isolation rating ensuring electrical safety between windings

Power Transformers Applications

• Industrial machinery control circuits
• Power transmission and distribution systems
• Electrical equipment requiring isolated power sources

Power Transformers Procurement Notes

Verify the specific secondary configuration required (parallel 6V vs. series 12V CT) against the application schematic. Confirm that terminal block termination aligns with the system wiring harness. Ensure the chassis mounting style fits the enclosure constraints. Cross-reference the primary voltage taps with the available supply network to ensure proper connection.

Power Transformers Selection Notes

Select this model when a 250 VA capacity is necessary with versatile input voltage ranges. The dual secondary arrangement allows adaptation for different load requirements without changing the transformer unit. Consider the physical size and terminal block interface during mechanical design integration to ensure compatibility with existing assembly processes.

Power Transformers Part Context

This component belongs to the MPI series of standard power transformers from Signal Transformer. These units are designed for industrial applications requiring reliable voltage transformation. The series offers various power ratings and configurations to meet diverse electrical standards and operational environments.

Power Transformers Replacement Considerations

Direct substitutes must match the 250 VA rating, 100-230 VAC primary range, and 6V/12V secondary outputs. Verify identical termination styles and mounting dimensions to ensure fitment. Consult manufacturer cross-reference lists for equivalent part numbers with confirmed electrical parity.
