DP-241-4-28

Power Transformers Overview

The DP-241-4-28 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 Hz or 60 Hz. The single secondary winding provides a center-tapped output of 28 VCT with an RMS current rating of 200 mA. With a power capacity of 6 VA, it utilizes quick connect terminals for electrical connections. The unit is designed for chassis mounting and operates within a temperature range of -40°C to +105°C.

Power Transformers Feature Summary

• Utilizes a split bobbin construction to provide superior isolation between windings
• Features dual primary windings allowing flexible input voltage selection
• Designed for robust industrial control applications with high thermal stability

Power Transformers Applications

• Industrial control panels requiring isolated power supply
• Chassis-mounted equipment needing compact transformer solutions
• Servo systems and computer components requiring stable AC voltage conversion

Power Transformers Procurement Notes

Verify that the specific order matches the DP-241-4-28 designation to ensure correct secondary voltage and current ratings. Confirm chassis mounting requirements align with physical dimensions. Check terminal type compatibility with existing wiring harnesses. Ensure operating environment temperatures remain within the specified -40°C to +105°C range for reliable performance.

Power Transformers Selection Notes

Select this component when a 6 VA capacity is sufficient for the load requirements. Choose based on the need for 28 VCT output derived from standard 115/230 VAC inputs. Consider the split bobbin design if enhanced isolation is critical for the application safety standards. Verify that quick connect terminals are compatible with the system's interconnection method.

Power Transformers Part Context

This model belongs to the Two-4-One series, which emphasizes compact size and high efficiency in industrial transformers. The series is characterized by its split bobbin technology, offering better isolation than traditional wound cores. These transformers are widely used in applications where space constraints and thermal performance are key design factors.

Power Transformers Replacement Considerations

Direct substitutes within the same series include DP-241-5-28, which offers higher current capacity. Other models in the 241 series may serve as alternatives if different voltage ratios are acceptable. Always verify pinout and dimensional compatibility before swapping.
