VPM30-3330

Power Transformers Overview

The VPM30-3330 is a medical-grade toroidal power transformer from Triad Magnetics, rated at 100 VA. It features primary input taps for 100V, 120V, 220V, and 240V AC operation at 50/60 Hz. The secondary output provides 30V CT (Center Tap) at 3.33A. This unit offers 4 kV dielectric isolation and includes resettable over-temperature protection. Its shielded construction minimizes stray magnetic fields.

Power Transformers Feature Summary

• Medical-grade toroidal design with 4 kV dielectric isolation
• Shielded construction to minimize stray electromagnetic fields
• Integrated resettable over-temperature protection mechanism
• Single-transformer solution eliminating need for separate isolation units

Power Transformers Applications

• Medical equipment power supplies
• Industrial control systems requiring isolation
• Alternative energy applications
• General purpose low-voltage step-down conversion

Power Transformers Procurement Notes

Verify that the specific application requires medical-grade certification and 4 kV isolation. Confirm primary voltage tap configuration matches the local supply network. Ensure thermal management accommodates the transformer's temperature rise characteristics. Check mechanical dimensions against enclosure constraints. Validate that the 30V CT output aligns with downstream rectification requirements.

Power Transformers Selection Notes

Select this model when space efficiency and low noise are critical compared to EI transformers. Choose the VPM series for designs needing integrated isolation rather than adding external components. Consider the available voltage taps for global compatibility. Evaluate the 100 VA rating against peak load demands to ensure adequate capacity without excessive size.

Power Transformers Part Context

Part of the VPM series, which ranges from 25 VA to 10 KVA. Designed to replace standard 1:1 isolation transformers in non-medically rated designs. Offers higher efficiency and smaller footprint. Available in various output voltages including 6V, 9V, 12V, 15V, 18V, 24V, 30V, 36V, 48V, and 120V AC.

Power Transformers Replacement Considerations

No direct substitute part numbers are publicly confirmed in the provided documentation. When replacing, ensure the new component matches the 100 VA rating, 30V CT output, and 4 kV isolation requirement. Verify physical mounting dimensions and terminal configurations.
