241-4-120L

Power Transformers Overview

The Signal Transformer 241-4-120L is a laminated core power transformer rated at 6 VA. It features a single primary winding designed for 115 VAC input and a single secondary winding providing 120 VCT output at 50 mA. The unit utilizes chassis mounting with wire lead termination. Physical dimensions are 60.30 mm in length, 33.30 mm in width, and a maximum installation height of 36.20 mm. It operates at 50/60 Hz frequencies and offers 2500Vrms isolation voltage.

Power Transformers Feature Summary

• Split bobbin construction provides superior electrical isolation and low capacitive coupling between windings.

Power Transformers Applications

• Industrial power supply units requiring isolated AC voltage conversion
• Chassis-mounted equipment needing 115V to 120VCT step-up transformation
• General purpose electronic systems utilizing laminated core transformers

Power Transformers Procurement Notes

Verify the specific suffix 'L' indicates wire leads rather than quick connects when comparing against similar models like the 241-4-120. Confirm that the 120 VCT secondary specification matches the load requirements. Ensure the chassis mount footprint aligns with the mechanical design constraints. Check RoHS compliance status if required by the final assembly specifications.

Power Transformers Selection Notes

Select this component when a 6 VA capacity is sufficient for the application load. The split bobbin design is critical for applications demanding high isolation integrity. Consider the physical size constraints as the unit requires significant chassis space compared to smaller surface mount alternatives. Verify that the 50 mA secondary current rating meets the peak demand of the connected circuitry without saturation.

Power Transformers Part Context

This model belongs to the Two-4-One series of industrial power transformers manufactured by Signal Transformer, now part of Bel Fuse. These transformers are characterized by their robust laminated core construction and standardized pinouts. The series is widely used in legacy and modern industrial control panels where reliable AC power distribution is required.

Power Transformers Replacement Considerations

Public confirmed substitutes include the DP-241-4-120L. Verify compatibility regarding terminal type and mounting hole spacing before substitution.
