Overview
The DP-241-5-120L is a laminated core power transformer from the Two-4-One series, rated at 12 VA. It features dual primary windings supporting 115 VAC and 230 VAC inputs at 50/60 Hz. The secondary provides a single 120 V CT output with a current rating of 100 mA. Designed for chassis mounting, it utilizes screw termination. Physical dimensions are 71.4 mm length, 36.3 mm width, and 42.8 mm height. It offers 2500 Vrms isolation and operates within a temperature range of -40°C to +105°C.
Feature Summary
- Dual primary winding configuration enables flexible input voltage selection between 115 VAC and 230 VAC.
- Center-tapped secondary design facilitates full-wave rectification applications requiring balanced positive and negative rails.
- Chassis mount construction with screw terminals ensures secure mechanical installation and robust electrical connections.
Applications
- Industrial control panel power supplies
- Equipment requiring isolated DC power conversion
- Test and measurement instrument internal power stages
Procurement Notes
Verify that the specific order matches the DP-241-5-120L designation, as similar part numbers in the 241 series may differ in winding configuration or voltage ratings. Confirm RoHS compliance status if required by project specifications. Ensure chassis mounting hardware compatibility with the specified terminal type before integration into the final assembly.
Selection Notes
Select this component when a 12 VA capacity is sufficient for the load requirements. The dual primary feature simplifies inventory management for global deployments by accommodating both 115V and 230V regions without separate SKUs. Verify that the physical envelope fits within the designated chassis space and that the center-tapped output aligns with the circuit topology.
Part Context
This model belongs to Signal Transformer's Two-4-One series, which consolidates multiple standard transformer variants into fewer stock keeping units. The series utilizes laminated core technology suitable for general-purpose industrial frequencies. It serves as a standardized solution for replacing various discrete transformers in legacy equipment designs requiring similar electrical characteristics.
Replacement Considerations
Public confirmed substitute part numbers include 241-5-120 and DP-241-5-120. Verify that any replacement maintains identical pinout, mounting hole spacing, and electrical ratings to ensure direct interchangeability without PCB redesign.
