BV030-7085.0

Overview

The BV030-7085.0 is a laminated core power transformer manufactured by Pulse Electronics, designed for through-hole mounting. It features a dual primary winding configuration supporting 115V and 230V inputs connected in parallel. The secondary side consists of dual windings providing 18V outputs, which can be configured in series for 36V or kept in parallel to deliver up to 554mA of current. With a maximum power rating of 10VA, this component serves as a fundamental isolation element in AC power supply circuits requiring standard line voltage compatibility.

Feature Summary

• Dual primary winding design enables flexible operation across 115V and 230V AC input lines via parallel connection.
• Dual secondary windings allow configurable output voltages of 18V (parallel) or 36V (series) with combined current capacity.
• Laminated core construction provides efficient magnetic coupling and electrical isolation between primary and secondary circuits.

Applications

• AC-to-DC power supply units
• Industrial control system power modules
• Consumer electronics equipment transformers

Procurement Notes

Verify the specific datasheet version and manufacturer documentation to confirm pinout configurations and insulation ratings before integration. Ensure that the procurement source provides authentic components from Pulse Electronics, as obsolete status may require careful sourcing validation. Cross-reference the part number against official distributor catalogs to confirm availability and authenticity.

Selection Notes

Select this transformer when a 10VA isolation capability is required with dual primary voltage support. The dual secondary configuration offers flexibility for different voltage requirements without changing hardware. Consider thermal management and physical space constraints associated with through-hole mounting in the final enclosure design.

Part Context

This component belongs to the broader category of laminated core power transformers used for mains frequency isolation. It is distinct from switching mode power supplies or high-frequency transformers, serving instead as a passive step-down or isolation stage in linear or rectified power architectures.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Due to the obsolete product status, alternative selection requires manual verification of electrical parameters such as VA rating, winding ratios, and physical dimensions against the original design specifications.
