Overview
The DPC-28-160 is a laminated core power transformer from the Signal Transformer PC series, rated at 4.4 VA. It features dual primary windings supporting 115V and 230V inputs. The secondary configuration provides two outputs: 14V at 320mA and 28V center-tapped at 160mA. Designed for through-hole mounting with PC pin termination, it operates within a frequency range of 50 Hz to 500 Hz. The unit measures 34.9mm in height and complies with RoHS standards.
Feature Summary
- Dual primary winding design accommodates multiple input voltage configurations
- Laminated core construction ensures efficient magnetic coupling
- Through-hole mounting facilitates secure PCB integration
Applications
- General purpose AC to DC power supply circuits
- Industrial control system power modules
- Electronic equipment requiring isolated low-voltage DC sources
Procurement Notes
Verify that the specific order matches the manufacturer part number DPC-28-160 from Signal Transformer or Bel Signal Transformer. Confirm compliance requirements such as RoHS status and UL/CSA approvals against the official datasheet. Ensure the procurement channel provides authentic components with traceable documentation to avoid counterfeit risks during assembly.
Selection Notes
Select this component when a 4.4 VA isolation transformer is required for 50-500 Hz operation. The dual secondary outputs allow flexible voltage generation for different circuit rails. Verify physical footprint constraints against the 34.9mm height specification. Ensure the application current demands do not exceed the 320mA and 160mA ratings for the respective secondary windings.
Part Context
This model belongs to the PC/DPC series of miniature low-power transformers by Signal Transformer. These units are characterized by their compact laminated core design and through-hole compatibility. The series is widely utilized in applications demanding reliable electrical isolation and stable voltage transformation within small form factors.
Replacement Considerations
Cross-reference with other models in the PC series for similar VA ratings. Verify that any substitute maintains identical primary voltage support and secondary output specifications. Ensure mechanical dimensions and pinout configurations remain compatible with existing PCB layouts.
