Overview
The DST7-24B55 is a laminated core power transformer manufactured by Pulse Electronics. It features a low-frequency open-style design with a split bobbin construction and horizontal plug-in mounting. The unit has a rated power of 36VA. The primary winding supports parallel connection for 115V and 230V input voltages. The secondary configuration includes parallel windings providing 12V at 3A and series windings providing 24V at 1.5A. Physical dimensions are 66.8 mm in length, 55.63 mm in width, and 39.62 mm in height.
Feature Summary
- Laminated core construction for efficient magnetic flux transfer
- Split bobbin design facilitating specific winding arrangements
- Horizontal plug-in mounting style for board integration
Applications
- General purpose AC to DC power conversion circuits
- Industrial equipment requiring isolated power supplies
- Electronic systems utilizing multiple secondary voltage rails
Procurement Notes
Verify the specific datasheet version provided by the manufacturer or authorized distributor to confirm electrical tolerances and mechanical drawings. Ensure that the primary voltage configuration matches the target application's input requirements before finalizing procurement. Cross-reference the part number with official component databases to validate authenticity and current production status.
Selection Notes
Select this component when an open-style laminated transformer is required for applications needing both 12V and 24V outputs from a single unit. Consider the physical footprint constraints as the device utilizes a horizontal plug-in form factor. Evaluate the thermal performance characteristics against the ambient operating conditions of the intended enclosure to ensure reliable operation under load.
Part Context
This transformer belongs to the DST7 series of low-frequency power transformers from Pulse Electronics. The series is characterized by open-style laminated cores and split bobbin architectures designed for through-hole or plug-in mounting. These components serve as fundamental isolation elements in power supply designs where standard encapsulated transformers do not meet specific voltage or form factor requirements.
Replacement Considerations
No public confirmed substitute part numbers are available in the provided documentation.
