Overview
The BV020-5390.0 is a laminated core power transformer manufactured by Pulse Electronics, designed for chassis mounting applications. It features a primary voltage rating of 230V and offers versatile secondary configurations with parallel outputs at 12V or series outputs at 24V. The maximum output current is specified as 42mA in parallel configuration. The unit has a compact physical footprint measuring 23 mm in length, 22 mm in width, and 19 mm in height. It operates within a temperature range from 0°C to +70°C and is rated for 0.5VA power handling capacity.
Feature Summary
- Laminated core construction for efficient magnetic coupling
- Versatile secondary winding options supporting parallel 12V or series 24V outputs
- Chassis mount design for secure mechanical installation
Applications
- Low-power AC/DC conversion circuits
- Industrial control panel isolation
- Signal conditioning power supplies
Procurement Notes
Verify the specific secondary configuration required (parallel 12V vs. series 24V) against the application schematic before ordering. Confirm that the 42mA current rating meets the load requirements. Ensure chassis mounting hardware is compatible with the component dimensions. Check for any updated datasheet revisions regarding insulation ratings or safety certifications prior to final design approval.
Selection Notes
Select this component when a small form factor laminated transformer is needed for low-current applications. The 0.5VA rating suits light loads where higher efficiency surface-mount alternatives are not feasible. Consider the thermal limitations of the +70°C maximum operating temperature during enclosure design. Verify input voltage compatibility with the 230V primary specification.
Part Context
This part belongs to Pulse Electronics' line of general-purpose power transformers. The BV020 series typically utilizes laminated steel cores to provide reliable isolation and voltage transformation in compact enclosures. These components are commonly used in legacy or cost-sensitive designs where through-hole or chassis mounting is preferred over surface-mount technology.
Replacement Considerations
No direct public substitute part numbers are confirmed for this specific model. When replacing, ensure the new component matches the 230V primary, 0.5VA rating, and physical mounting dimensions. Verify electrical isolation standards and frequency response if operating conditions differ from standard mains frequencies.
