Overview
The BV042-5386.0 is a laminated core power transformer manufactured by Pulse Electronics. It features a 230V primary winding and a single 24V secondary output. The unit provides an apparent power rating of 5.4 VA, supporting a maximum secondary current of 208 mA. Designed for through-hole mounting, this component utilizes a standard EI core configuration suitable for general-purpose AC-to-AC voltage conversion in electronic equipment requiring isolated power supplies.
Feature Summary
- Laminated core construction for efficient magnetic flux transfer
- Single secondary winding providing isolated 24V output
- Through-hole mounting style for secure PCB integration
Applications
- General purpose AC to AC voltage transformation
- Isolated power supply stages in electronic equipment
- Control circuitry requiring 24V secondary power
Procurement Notes
Verify the specific datasheet documentation for the BV042-5386.0 to confirm insulation class and safety certifications required for your target market. Ensure that the through-hole footprint dimensions match your printed circuit board layout constraints. Cross-reference the primary voltage rating with your input source to prevent operational mismatch. Confirm that the thermal characteristics align with the expected operating environment of the final assembly.
Selection Notes
Select this transformer when a 230V to 24V isolation ratio is required with a 5.4 VA capacity. The through-hole design offers mechanical stability compared to surface-mount alternatives. Consider the physical size constraints of the enclosure, as laminated core transformers typically require more volume than switched-mode solutions. Verify that the 208 mA load current does not exceed the rated limit under all operating conditions to maintain performance.
Part Context
This component belongs to the BV042 series of power transformers from Pulse Electronics. The series generally covers various voltage configurations using laminated core technology. These transformers are designed for reliability in standard industrial and commercial applications. The BV042-5386.0 specifically addresses the common need for stepping down mains voltage to a lower AC level for downstream rectification or control logic.
Replacement Considerations
Public confirmed substitute part numbers include ASL131124K. This alternative offers similar electrical specifications with a 5.4 VA rating and 24V secondary output. Verify mechanical compatibility before substitution.
