DP-241-8-28L

Overview

The Signal Transformer DP-241-8-28L is a laminated core power transformer designed for industrial control applications. It features a dual primary winding configuration supporting 115 VAC and 230 VAC input voltages at 50 Hz or 60 Hz operating frequencies. The unit delivers a 100 VA power rating with a single secondary output of 28 VCT. Maximum secondary current is rated at 3.6 A. The device utilizes chassis mounting and screw termination types, ensuring robust mechanical integration within equipment enclosures.

Feature Summary

• Utilizes a split bobbin design to provide superior electrical isolation and minimize capacitive coupling between windings.
• Features dual primary windings allowing flexible connection to either 115 VAC or 230 VAC power sources.
• Constructed with a laminated core to efficiently handle 100 VA power ratings in industrial environments.

Applications

• Industrial control panels requiring isolated power distribution
• Equipment needing 28 VCT supply for control circuits
• Chassis-mounted systems demanding high isolation standards

Procurement Notes

Verify the specific voltage configuration and physical dimensions against the target enclosure requirements before ordering. Confirm that the chassis mounting style and screw termination type align with the assembly infrastructure. Ensure the operating frequency range of 50/60 Hz matches the local power grid specifications to guarantee proper transformer performance and thermal management under full load conditions.

Selection Notes

Select this model when a 100 VA capacity is required with a 28 VCT secondary output. The dual primary winding capability makes it suitable for global deployment across regions using different standard voltages. Consider the chassis mount requirement and physical footprint constraints during the design phase to ensure compatibility with the intended housing structure.

Part Context

This component belongs to the Two-4-One series from Signal Transformer, which emphasizes high isolation through split bobbin construction. The DP-241 series is engineered for industrial durability, offering reliable performance in control applications where electrical noise reduction and secure mounting are critical for system stability and safety compliance.

Replacement Considerations

Direct substitutes within the same series include models with identical VA ratings but different secondary voltages, such as the DP-241-8-28L variants. Verify pinout compatibility and mounting hole patterns when considering alternative part numbers from the manufacturer's catalog to ensure seamless integration without mechanical modifications.
