DP-241-4-120

Overview

The DP-241-4-120 is a laminated core power transformer from the Two-4-One series, designed for industrial control applications. It features dual primary windings rated for 115 VAC and 230 VAC input, providing versatility across different supply standards. The secondary output delivers 120 VCT at a maximum current of 50 mA, with a total power rating of 6 VA. Constructed with a split bobbin design, it ensures superior isolation and low capacitive coupling between windings. The unit utilizes quick connect terminals for chassis mounting and operates within a temperature range of -40°C to +105°C at 50/60 Hz frequencies.

Feature Summary

• Split bobbin construction provides superior electrical isolation and minimizes capacitive coupling between windings.
• Dual primary winding configuration allows flexible operation on both 115 VAC and 230 VAC supply lines.
• Chassis mount design with quick connect termination facilitates straightforward integration into industrial control panels.

Applications

• Industrial control systems requiring isolated power supplies
• Equipment needing 120 VCT secondary voltage for control circuits
• Applications demanding high isolation standards in compact chassis mounts

Procurement Notes

Verify that the specific order matches the DP-241-4-120 designation to ensure correct 6 VA rating and 120 VCT output. Confirm terminal type compatibility with existing panel wiring harnesses. Check environmental ratings against operational temperature requirements. Ensure chassis mounting dimensions align with enclosure specifications prior to procurement.

Selection Notes

Select this model when a 6 VA isolated power source is required for control logic or signaling circuits. The dual primary capability makes it suitable for global deployment where input voltages vary between 115 VAC and 230 VAC. The split bobbin architecture is preferred over standard cores when strict isolation and reduced noise coupling are critical system requirements.

Part Context

This component belongs to Signal Transformer's Two-4-One series, which emphasizes standardized form factors with varied electrical configurations. The 241 series utilizes laminated core technology optimized for 50/60 Hz operations. This specific part represents a mid-range power option within the series, balancing physical size with sufficient isolation capabilities for sensitive industrial instrumentation.

Replacement Considerations

Direct substitutes include the 241-5-120 for higher power needs or other 241-series variants with matching voltage ratings. Hammond Manufacturing 186D120 is listed as an alternative in some catalogs. Verify pinout and mounting hole alignment when cross-referencing with competitor models to ensure mechanical fit.
