Overview
The Signal Transformer DP-241-8-28 is a laminated core power transformer rated at 100 VA. It features dual primary windings supporting 115 VAC and 230 VAC inputs at 50/60 Hz frequencies. The secondary output provides 28 VAC center-tapped (CT) at 3.6 A. Designed for chassis mounting, it utilizes screw terminals for connection. The unit employs a split bobbin construction to ensure superior isolation and low capacitive coupling between windings.
Feature Summary
- Split bobbin design for superior isolation
- Dual primary winding configuration
- Laminated core construction
Applications
- Industrial Automation
- Industrial Control Systems
- PLC Programming Equipment
Procurement Notes
Verify the specific voltage rating and current capacity against the application requirements before ordering. Confirm that the chassis mounting style and screw terminal interface are compatible with the intended enclosure design. Ensure the input frequency range matches the local power supply standards to guarantee proper operation and safety compliance.
Selection Notes
Select this component when a 100 VA power rating is required for industrial control applications. The dual primary winding allows flexibility for different input voltages. The split bobbin architecture is suitable for environments requiring high isolation standards. Consider the physical dimensions and chassis mount requirement during the mechanical design phase.
Part Context
This model belongs to the TWO-4-ONE series of transformers from Signal Transformer. The series is characterized by laminated core technology and split bobbin construction. These transformers are designed for general industrial use where reliable power conversion and electrical isolation are critical for system stability.
Replacement Considerations
Direct substitutes within the same series include models with similar VA ratings and voltage configurations. Verify that any replacement maintains the 100 VA rating and 28 VCT secondary output. Ensure the physical footprint and mounting hole pattern match the existing installation to avoid mechanical modifications.
