Overview
The BV301D24018 is a 1.8VA encapsulated power transformer from Zettler Magnetics, designed for through-hole mounting. It features an EI30_18 lamination size with dimensions of 32.8x27.8mm and a height of 24.5mm. The unit operates at 40C temperature rise with an input voltage of 115V. The secondary output provides 2x24V at 37.5mA. Weighing 80g, this component utilizes vacuum pressure encapsulation to ensure compactness and efficiency in linear power supply applications.
Feature Summary
- Fully encapsulated under vacuum pressure for enhanced efficiency and compact form factor
- EI30 lamination construction supporting standard through-hole PCB integration
- Dual secondary winding configuration providing isolated 2x24V output
Applications
- Linear power supply circuits requiring isolated AC voltage conversion
- Electronic equipment utilizing 115V primary input sources
- Control systems needing dual 24V secondary outputs
Procurement Notes
Verify the specific ordering suffix against official Zettler Magnetics documentation to confirm electrical characteristics and mechanical footprint. Ensure compatibility with target PCB layout regarding through-hole spacing and case dimensions. Cross-reference datasheet specifications for input frequency and temperature ratings prior to integration.
Selection Notes
Select this component when a 1.8VA capacity is required for 115V primary applications. The EI30 core size and encapsulation method suit designs prioritizing thermal stability and electromagnetic shielding. Confirm that the 2x24V secondary configuration aligns with downstream circuit requirements without additional rectification complexity.
Part Context
This model belongs to the BV series of laminated power transformers manufactured by Zettler Magnetics. The series emphasizes vacuum-encapsulated construction to reduce size while maintaining performance. These units are distinct from toroidal or open-frame designs, offering a standardized solution for general-purpose AC-to-AC transformation in industrial electronics.
Replacement Considerations
Consult official substitution lists for equivalent VA ratings and pin configurations. Verify that alternative models match the 115V input and 2x24V output specifications. Ensure mechanical compatibility with existing PCB holes and enclosure constraints before implementing any substitute part number.
