Overview
The Signal Transformer DP-241-7-28 is a laminated core power transformer designed for industrial applications. It features a dual primary winding configuration supporting 115 VAC and 230 VAC input voltages at 50/60 Hz frequencies. The unit delivers a maximum power rating of 56 VA with a single secondary output of 28 VAC at 2 A. Constructed with a split bobbin design, it provides superior isolation and low capacitive coupling. The component utilizes chassis mounting with screw terminals and offers 2500 Vrms isolation voltage.
Feature Summary
- Split bobbin construction for enhanced electrical isolation
- Dual primary winding capability for flexible voltage input
- Laminated core design optimized for industrial environments
Applications
- Industrial control systems requiring isolated power supplies
- Chassis-mounted equipment needing high isolation voltage
- Power distribution units utilizing split bobbin transformers
Procurement Notes
Verify the specific terminal type and mounting flange dimensions against the mechanical drawing before integration. Confirm that the 56 VA rating aligns with the thermal management capabilities of the target enclosure. Ensure input voltage selection matches the dual primary winding requirements to prevent operational failure. Cross-reference the datasheet version for any recent packaging or compliance updates.
Selection Notes
Select this model when high isolation voltage and robust industrial durability are required. The split bobbin architecture distinguishes it from standard laminated cores by reducing capacitive coupling. Consider the chassis mount style and terminal configuration for panel integration. Evaluate the 56 VA capacity against peak load requirements to ensure adequate headroom for transient currents in critical applications.
Part Context
This component belongs to the DP-241 series of industrial power transformers. The series utilizes split bobbin technology to achieve superior performance characteristics compared to conventional designs. These transformers are engineered for reliability in demanding environments, offering consistent electrical isolation and efficient power transfer through their laminated core structures.
Replacement Considerations
Direct substitutes within the same series include DP-241-5-10L and DP-241-6-12L. Verify that alternative models match the required power rating and secondary voltage specifications. Ensure mechanical compatibility regarding chassis mounting dimensions and terminal types before swapping components.
