Overview
The DP-241-5-12L is a laminated core power transformer from the Two-4-One series by Signal Transformer. It features dual primary windings rated for 115 VAC and 230 VAC operation at 50/60 Hz. The single secondary winding provides 12.6 VCT at a maximum current of 1.0 A, resulting in a 12 VA power rating. Designed for chassis mounting with screw terminals, it measures 71.4 mm in length, 36.3 mm in width, and 42.8 mm in height. The unit supports an operating temperature range of -40°C to +105°C.
Feature Summary
- Dual primary winding configuration allows flexible connection to either 115 VAC or 230 VAC input sources.
- Center-tapped secondary output facilitates full-wave rectification circuits requiring split voltage rails.
- Chassis mount design with screw terminals ensures secure mechanical installation and robust electrical connections.
Applications
- Industrial control panel power supplies
- Equipment requiring isolated AC-to-AC voltage conversion
- Rectifier circuit inputs for DC power generation
Procurement Notes
Verify that the specific application requires a center-tapped secondary configuration, as this component outputs 12.6 VCT rather than a standard single-voltage secondary. Confirm that the chassis mounting style and screw terminal interface are compatible with the intended enclosure design. Ensure the thermal environment remains within the specified -40°C to +105°C operating range to maintain performance and safety compliance.
Selection Notes
Select this model when a 12 VA capacity is sufficient for the load requirements. The dual primary feature makes it suitable for global deployment where input voltages vary between 115 VAC and 230 VAC. Consider the physical dimensions of 71.4 x 36.3 x 42.8 mm during layout planning. This transformer is appropriate for applications needing reliable isolation and a center-tapped output for bridge or full-wave rectifier topologies.
Part Context
This component belongs to the DP-241 series, which utilizes laminated core technology for efficient magnetic flux transfer. The Two-4-One series designation indicates standardized form factors designed to replace multiple legacy part numbers. Signal Transformer manufactures these units to meet industrial reliability standards, ensuring consistent performance across various environmental conditions and operational frequencies.
Replacement Considerations
Direct substitutes may include other 12 VA transformers with identical 12.6 VCT secondary ratings and dual primary capabilities. Verify that any replacement matches the chassis mounting footprint and terminal type. Cross-reference specifications to ensure equivalent isolation voltage and thermal ratings are maintained in the new component.
