MPI-400-20

Power Transformers Overview

The MPI-400-20 is a laminated core power transformer manufactured by Signal Transformer, designed for chassis mount applications. It features dual primary windings supporting international input voltages of 100V, 115V, 200V, 215V, and 230V in parallel configuration. The secondary output provides 20VCT in series (20A) or 10V in parallel (40A). Rated at 400VA with a dielectric strength of 4000 Vrms, it operates at 50/60Hz frequencies.

Power Transformers Feature Summary

• Dual primary winding design enables compatibility with multiple international voltage standards including 100V, 115V, 200V, 215V, and 230V.
• Flexible secondary output configuration allows selection between 20VCT at 20A in series mode or 10V at 40A in parallel mode.
• High dielectric strength rating of 4000 Vrms ensures robust electrical isolation for industrial safety requirements.

Power Transformers Applications

• Industrial equipment requiring multi-voltage input compatibility
• Chassis-mounted power supply systems
• International electronic devices needing flexible AC power conversion

Power Transformers Procurement Notes

Verify the specific secondary current requirement against the datasheet before ordering. Confirm that the chassis mounting dimensions align with the enclosure design. Ensure the operating frequency matches the system's 50/60Hz specification. Check for any regional shipping restrictions due to weight or size limitations associated with this component class.

Power Transformers Selection Notes

Select this model when dual primary voltage flexibility is required for global deployment. The choice between series and parallel secondary outputs depends on the target current load. Consider the physical dimensions and chassis mounting style during mechanical integration. Verify thermal management needs based on the 400VA power rating and ambient operating conditions.
