Overview
The Signal Transformer DPC-24-35 is a laminated core power transformer with a maximum power rating of 1VA. It features dual primary windings rated for 115V and 230V operation, and dual secondary windings providing parallel 12V or series 24V outputs at full load. The device supports a maximum output current of 1A in series configuration. It utilizes through-hole PC pin termination and offers 1500Vrms isolation voltage. The unit measures 25.4mm in length, 21.08mm in height, and weighs approximately 71.21g.
Feature Summary
- Laminated core construction for standard frequency applications
- Dual primary and dual secondary winding configurations
- Through-hole mounting with PC pin termination
Applications
- Low-power AC to DC power supply circuits
- Industrial control systems requiring isolated power
- Consumer electronics with low VA requirements
Procurement Notes
Verify the specific datasheet version for the DPC-24-35 model, as manufacturer catalogs may list variations within the DPC series. Confirm that the 1VA rating aligns with your design requirements, distinguishing it from higher-capacity variants like the DPC-16-1500. Ensure compatibility with 50/60 Hz input frequencies. Check RoHS compliance status for environmental regulations. Validate physical dimensions against PCB layout constraints before finalizing procurement.
Selection Notes
Select this component when a compact, low-power transformer is needed for isolated power conversion. The dual secondary option allows flexibility between 12V parallel and 24V series connections. Ensure the application does not exceed the 1A current limit. Compare physical size against available board space, noting the 21.08mm height. Verify that the 1500Vrms isolation meets safety standards for the target equipment.
Part Context
The DPC-24-35 belongs to the DPC series of miniature low-power transformers manufactured by Signal Transformer. This series is characterized by laminated cores and through-hole packaging. It serves as a lower-power alternative to higher VA models within the same family, such as the 24VA DPC-16-1500. The product is designed for general-purpose power transformation in compact electronic assemblies.
Replacement Considerations
Direct substitutes include other 1VA laminated transformers with identical 115/230V primary and 12V/24V secondary ratings. Verify pinout compatibility and physical footprint equivalence. Models from other manufacturers offering similar electrical specifications and through-hole mounting may serve as alternatives if dimensional constraints are met.
