BV301S12028

Overview

The BV301S12028 is a 2.8VA encapsulated power transformer from Zettler Magnetics, designed for through-hole mounting. It features an EI30 laminated core with a case dimension of 32.8x27.8mm and a height of 29.8mm. The unit operates at 50/60Hz with a primary input voltage of 115V and provides a secondary output voltage of 12V at 233mA. This component is classified under the BV Series of encapsulated power transformers.

Feature Summary

• Encapsulated construction for environmental protection
• EI30 laminated core design
• Through-hole mounting configuration

Applications

• General purpose AC-DC power supply circuits
• Low power electronic equipment requiring isolated DC rails
• Control panel power distribution

Procurement Notes

Verify the specific datasheet version to confirm electrical tolerances and insulation ratings. Ensure the application environment supports the thermal characteristics of encapsulated transformers. Confirm that the 115V primary rating aligns with the local mains frequency and voltage standards. Check for any regional certification requirements such as CQC or UL depending on the target market.

Selection Notes

Select this model when a compact 2.8VA isolation transformer is required for 115V primary applications. The encapsulated design offers robustness against moisture and dust compared to open cores. Consider the physical dimensions of 32.8x27.8mm for PCB layout constraints. Verify that the 12V output current requirement does not exceed 233mA under full load conditions.

Part Context

This component belongs to the BV Series of encapsulated power transformers by Zettler Magnetics. The series utilizes EI30 laminations and is available in various voltage configurations. It is distinct from toroidal transformers which offer higher efficiency but different form factors. The BV series focuses on cost-effective solutions for standard low-power applications.

Replacement Considerations

Direct substitutes must match the 2.8VA rating, 115V primary, 12V secondary, and through-hole package. Verify core size compatibility (EI30) and case dimensions to ensure mechanical fit. Cross-reference manufacturer-specific part numbers for equivalent performance.
