DP-241-4-56

Overview

The Signal Transformer DP-241-4-56 is a laminated core power transformer designed for industrial control applications. It features dual primary windings rated for 115 VAC and 230 VAC operation at 50/60 Hz frequencies. The unit provides a single secondary output of 56 VCT with a current rating of 110 mA, delivering a maximum power capacity of 6 VA. Constructed with a split bobbin design, it ensures superior isolation and low capacitive coupling between windings. The component utilizes chassis mounting and quick connect termination types, supporting an operating temperature range from -40°C to +105°C.

Feature Summary

• Split bobbin construction providing superior electrical isolation and reduced capacitive coupling
• Dual primary winding configuration allowing flexible connection to 115 VAC or 230 VAC supply lines
• Chassis mount style with quick connect terminals for secure installation and wiring

Applications

• Industrial control systems requiring isolated power supplies
• Equipment needing 56 VCT secondary voltage for control circuits
• General purpose power transformation in 50/60 Hz AC environments

Procurement Notes

Verify the specific datasheet version for the DP-241-4-56 to confirm terminal type and insulation class. Ensure the application environment stays within the specified -40°C to +105°C operating range. Confirm that the 6 VA power rating meets the load requirements of the target circuit. Check for compliance with relevant safety standards such as UL or IEC depending on the final equipment certification needs.

Selection Notes

Select this model when a compact, chassis-mounted transformer with high isolation is required for 50/60 Hz applications. The dual primary winding allows compatibility with both 115 VAC and 230 VAC input sources without rewinding. The split bobbin design is critical for applications demanding strict separation between primary and secondary circuits. Consider the 110 mA secondary current limit when designing the downstream load circuitry.

Part Context

The DP-241 series represents a line of laminated core power transformers from Signal Transformer. These components are characterized by their robust construction and reliable performance in industrial settings. The series includes various voltage and power ratings, with the DP-241-4-56 specifically offering a 56 VCT output. This part fits into the broader category of industrial control transformers used for stepping down mains voltage to lower levels for sensitive electronics.

Replacement Considerations

Direct substitutes may include other models from the Signal Transformer DP-241 series with matching 56 VCT outputs, such as DP-241-5-56 if higher current is acceptable. Cross-brand replacements must match the 6 VA power rating, 115/230 VAC primary inputs, and chassis mounting dimensions. Verify that any alternative maintains the split bobbin isolation characteristics and quick connect termination style.
