BV302S24012

Overview

The BV302S24012 is a laminated power transformer from the Zettler Magnetics BV series, designed for through-hole mounting. It features a 230V primary winding and a single 24V secondary output capable of delivering 50mA. The unit has a rated power capacity of 1.2VA and operates at standard frequencies of 50Hz or 60Hz. The core construction utilizes laminated steel, while the entire assembly is fully encapsulated under vacuum pressure to ensure structural integrity and electrical insulation. This configuration supports efficient linear power supply applications requiring reliable isolation between primary and secondary circuits.

Feature Summary

• Fully encapsulated construction under vacuum pressure for enhanced durability
• Laminated core design optimized for linear power efficiency
• Through-hole mounting style for standard PCB integration

Applications

• Linear power supply systems
• Industrial control equipment
• Consumer electronics requiring isolated AC-DC conversion

Procurement Notes

Verify the specific datasheet version with the manufacturer before procurement, as encapsulation materials and regulatory approvals may vary by production batch. Confirm that the 230V primary rating aligns with your local mains voltage standards. Ensure the 24V/50mA secondary specifications meet the load requirements of your target circuit. Cross-reference the package dimensions against your PCB footprint constraints to guarantee mechanical fit during assembly.

Selection Notes

Select this component when a compact, encapsulated transformer is required for low-power linear applications. The 1.2VA rating suits devices with modest current demands. Consider the through-hole form factor if surface-mount alternatives are unavailable or if higher mechanical stability is needed. Verify that the 24V output matches the downstream rectification and regulation stages. Evaluate thermal performance within the final enclosure to ensure safe operation under continuous load conditions.

Part Context

This model belongs to the BV series of encapsulated power transformers manufactured by Zettler Magnetics. The series emphasizes space-saving designs achieved through vacuum-pressure encapsulation. These units are positioned as cost-effective solutions for general-purpose power isolation in consumer and industrial hardware. The BV302S24012 specifically addresses markets needing standardized 24V outputs from high-voltage mains inputs.

Replacement Considerations

Direct substitutes include other BV series variants with matching VA ratings and pin configurations, such as the BV302S24010 or BV302D24012, provided the secondary current and voltage tolerances remain compatible. Always verify electrical parameters and physical dimensions before swapping components to maintain system reliability.
