Overview
The BV302D15028 is a 2.8VA laminated power transformer from the Zettler Magnetics BV series, designed for through-hole mounting. It features a 230V primary input compatible with 50/60Hz frequencies and provides a dual 15V secondary output (2x15V) capable of delivering 93mA per winding. The unit utilizes an EI30 lamination size with a maximum height of 29.8mm and case dimensions of 32.8x27.8mm. Fully encapsulated under vacuum pressure, it meets VDE TA40/B safety standards.
Feature Summary
- Fully encapsulated construction under vacuum pressure for enhanced efficiency and compactness
- Dual secondary windings providing isolated 15V outputs
- Through-hole mounting configuration for standard PCB integration
Applications
- Linear power supply circuits requiring isolated AC voltage
- Control systems utilizing 230V mains input
- Electronic equipment needing dual low-voltage secondary rails
Procurement Notes
Verify the specific ordering suffix against official Zettler Magnetics documentation to ensure correct electrical characteristics and pinout configuration. Confirm that the required insulation class and thermal rating align with the target application's environmental conditions before finalizing procurement.
Selection Notes
Select this component when a 2.8VA capacity is sufficient for the load requirements. Ensure the PCB layout accommodates the specified through-hole spacing and physical envelope dimensions. Verify that the 230V primary rating matches the available line voltage in the deployment region.
Part Context
This transformer belongs to the BV series of encapsulated power transformers manufactured by Zettler Magnetics. The series is characterized by vacuum-encapsulated laminated cores designed to provide smaller form factors and improved performance compared to non-encapsulated alternatives within the same power range.
Replacement Considerations
Consult official cross-reference lists for confirmed substitutes. Ensure replacement parts match the 2.8VA rating, 230V primary, 2x15V secondary specification, and EI30 core geometry.
