BV301S24028

Overview

The BV301S24028 is a single-phase encapsulated power transformer from the Zettler Magnetics BV series, designed for board mount applications. It features an EI30 laminated core construction with a rated power capacity of 2.8 VA. The unit operates with a primary input voltage of 115 VAC and provides a secondary output voltage of 24 VAC at a maximum current of 117 mA. The component utilizes through-hole mounting technology and measures 32.8 x 27.8 mm in case dimensions with a height of 29.8 mm. This configuration supports standard AC line frequencies and is engineered for reliable isolation in compact electronic assemblies.

Feature Summary

• Encapsulated construction provides environmental protection and mechanical stability for the internal windings and core.
• Single-phase design facilitates straightforward integration into standard AC-powered circuit architectures.
• Through-hole mounting ensures secure physical attachment to printed circuit boards during assembly.

Applications

• LED lighting systems requiring isolated low-voltage DC conversion
• Electric metering devices needing precise voltage step-down
• Motor control circuits utilizing small form-factor transformers
• Thermostat implementations with specific isolation requirements

Procurement Notes

Verify that the specific part number matches the required electrical specifications before ordering. Confirm that the 115V primary rating aligns with your local mains supply standards, as non-CQC approval applies to this input configuration. Ensure PCB layout accommodates the through-hole pin spacing and overall footprint dimensions. Check for any regional regulatory compliance needs distinct from the manufacturer's general certifications.

Selection Notes

Choose this model when a 2.8 VA isolation transformer is needed for 115V to 24V conversion. The encapsulated design suits environments where dust or moisture resistance is beneficial. Consider the physical size constraints relative to the 32.8 x 27.8 mm case dimensions. Evaluate if the single-phase requirement fits the system topology compared to multi-phase alternatives.

Part Context

This component belongs to the BV Series of encapsulated power transformers by Zettler Magnetics. The series is characterized by compact designs suitable for various commercial and industrial applications. The BV301S24028 specifically utilizes an EI30 lamination size, contributing to its efficiency and thermal performance within the defined power range.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Cross-referencing requires matching VA rating, voltage ratios, and physical footprint dimensions with other manufacturers' offerings.
