Overview
The Signal Transformer DP-241-4-28L is a laminated core power transformer rated at 6 VA. It features dual primary windings supporting 115 VAC and 230 VAC inputs, with a single secondary winding providing 28 VCT output at 200 mA. Designed for chassis mounting via wire leads, the unit measures 60.30 mm in length, 33.30 mm in width, and 36.20 mm in height. The component offers 2500 Vrms isolation voltage and operates at 50/60 Hz frequencies.
Feature Summary
- Dual primary winding configuration enables flexible input voltage selection between 115 VAC and 230 VAC.
- Single secondary winding provides center-tapped output suitable for full-wave rectification circuits.
- Chassis mount design utilizes wire leads for secure installation within industrial enclosures.
Applications
- Industrial machinery power supplies
- Electrical equipment control circuits
- Power transmission and distribution systems
Procurement Notes
Verify the specific datasheet version (ST-241-L) to confirm compliance with current RoHS3 standards and REACH regulations. Ensure that the wire lead termination style matches the target assembly requirements. Confirm that the 6 VA power rating and 200 mA secondary current capacity are sufficient for the intended load before finalizing procurement orders.
Selection Notes
Select this model when a compact 6 VA transformer is required for chassis-mounted applications. The dual primary winding allows operation in regions with either 115 VAC or 230 VAC mains without changing components. The 28 VCT output is appropriate for low-voltage DC conversion needs requiring center-tapped configurations.
Part Context
This component belongs to the Two-4-One series of standard power transformers manufactured by Signal Transformer. The series is characterized by laminated core construction and versatile primary voltage options. The DP-241-4-28L specifically addresses applications needing a small form factor with reliable isolation characteristics for industrial environments.
Replacement Considerations
Direct substitutes include other models from the DP-241 series with matching VA ratings and voltage specifications, such as the DP-241-4-24L or DP-241-4-12L, provided the secondary voltage requirements align with the circuit design.
FAQ
What is the isolation voltage rating?
The transformer provides an isolation voltage of 2500 Vrms between the primary and secondary windings.
Does the transformer support both 50 Hz and 60 Hz frequencies?
Yes, the DP-241-4-28L is designed to operate effectively at both 50 Hz and 60 Hz frequencies.
