BV302S24020

Overview

The BV302S24020 is a 2VA encapsulated power transformer from Zettler Magnetics, designed for through-hole PCB mounting. It features a 230VAC primary input and a single 24V secondary output rated at 83mA. The unit utilizes an EI30 laminated core with a maximum height of 15.5mm and a case dimension of 32.8x27.8mm. Operating at 50/60Hz, it provides electrical isolation between windings and meets standard safety requirements for low-power AC to DC conversion applications.

Feature Summary

• Encapsulated construction for environmental protection and mechanical stability
• EI30 laminated core design for efficient magnetic flux transfer
• Through-hole mounting configuration for secure PCB integration
• Single secondary winding providing isolated 24V output

Applications

• Low-power control circuitry in industrial equipment
• Power supply units for consumer electronics
• Signal isolation in measurement instruments
• General-purpose AC to DC conversion modules

Procurement Notes

Verify the specific datasheet revision and compliance certifications (such as UL or CE) directly with Zettler Magnetics or authorized distributors before procurement. Ensure that the thermal rating and insulation class meet the target application's safety standards. Confirm package dimensions and pin spacing compatibility with the printed circuit board layout to prevent assembly issues.

Selection Notes

Select this component when a compact, encapsulated transformer is required for 230VAC mains-powered systems needing a 24V output. The 2VA capacity suits low-current loads, while the EI30 form factor offers a balance between size and performance. Consider the through-hole requirement and physical dimensions against available board space and mounting constraints.

Part Context

This model belongs to the BV Series of encapsulated power transformers by Zettler Magnetics. The series typically includes variants with different secondary voltages and current ratings, all sharing similar EI30 core structures and encapsulation methods. The BV302S24020 specifically denotes the 24V output variant within this standardized product line.

Replacement Considerations

Direct substitutes include other BV302 series variants with identical VA ratings but different secondary voltages if voltage levels can be adjusted. Cross-reference with other manufacturers offering EI30 encapsulated transformers with matching 230VAC input and 2VA capacity, ensuring equivalent insulation and thermal specifications.
