Overview
The Signal Transformer DP-241-5-28 is a laminated core power transformer rated at 12 VA. It features dual primary windings supporting 115 VAC and 230 VAC inputs at 50/60 Hz. The secondary output provides 28 VCT at 0.42 A. Designed for chassis mounting, it utilizes screw terminals for connection. Physical dimensions are 71.4 mm in length, 36.3 mm in width, and 42.8 mm in height.
Feature Summary
- Split bobbin construction ensures superior electrical isolation and low capacitive coupling between windings.
- Dual primary winding design allows flexible operation across standard 115 VAC and 230 VAC line voltages.
- Chassis mount configuration with screw terminals facilitates secure installation in industrial control environments.
Applications
- Industrial control systems requiring isolated power supplies
- Equipment utilizing split bobbin transformers for enhanced safety
- General purpose power transformation in 50/60 Hz applications
Procurement Notes
Verify the specific voltage rating and current capacity against application requirements before ordering. Confirm that the chassis mounting style and screw terminal interface match the enclosure design. Ensure the 12 VA power rating meets the load demands of the downstream circuitry to prevent overheating or performance degradation during continuous operation.
Selection Notes
Select this component when high isolation is critical due to its split bobbin architecture. It is suitable for designs requiring compatibility with both 115 VAC and 230 VAC input sources without rewiring. Consider the physical footprint and chassis mount requirement as fixed constraints for the mechanical layout of the final assembly.
Part Context
This model belongs to the DP-241 series of industrial power transformers manufactured by Signal Transformer. The series is characterized by laminated core construction and split bobbin technology. These components are designed for reliability in demanding industrial environments, offering robust isolation characteristics compared to standard wound transformers.
Replacement Considerations
Direct substitutes within the same series include DP-241-5-10L and DP-241-5-56. Verify that alternative models provide compatible voltage outputs and current ratings. Ensure replacement parts maintain the same chassis mount form factor and terminal type for seamless integration.
