Overview
The BV301S09028 is a 2.8VA encapsulated power transformer from the Zettler Magnetics BV series, designed for through-hole mounting. It features a single primary winding rated for 115VAC input at 50/60Hz and a single secondary winding providing 9VAC output with a maximum current of 311mA. The component utilizes an EI30 laminated core structure housed in a compact case measuring 32.8mm x 27.8mm with a height of 29.8mm. This encapsulation provides environmental protection suitable for various industrial applications.
Feature Summary
- Encapsulated construction for enhanced environmental durability
- EI30 laminated core design for efficient magnetic performance
- Through-hole termination style for standard PCB integration
Applications
- LED lighting systems
- Electric metering devices
- Motor controls
- Thermostats
Procurement Notes
Verify the specific part number BV301S09028 against official Zettler Magnetics documentation to confirm electrical ratings and physical dimensions. Ensure compatibility with target PCB layouts regarding through-hole spacing and case height constraints. Cross-reference datasheets for insulation class and operating temperature ranges prior to final design approval.
Selection Notes
Select this component when a low-profile, encapsulated transformer is required for 115VAC to 9VAC conversion in space-constrained enclosures. The 2.8VA rating suits low-power control circuits. Consider the EI30 core size and encapsulation benefits over non-encapsulated alternatives for improved reliability in harsh environments or where mechanical stability is critical.
Part Context
This unit belongs to the BV series of encapsulated power transformers manufactured by Zettler Magnetics. The series is characterized by its suitability for LED lighting, electric metering, motor controls, and thermostats. The BV301S09028 specifically denotes the 2.8VA variant within the EI30_28 form factor family.
Replacement Considerations
Direct substitutes may include other BV series variants with similar VA ratings or different voltage outputs, such as BV301S10028 or BV301S12028, provided voltage requirements match. Verify that any replacement maintains the same encapsulation type, mounting style, and core geometry to ensure fitment.
