DPC-40-110

Overview

The Signal Transformer DPC-40-110 is a dual primary, single secondary power transformer designed for AC line voltage conversion. It features two 115VAC primary windings and a 28VAC secondary output, providing a total apparent power rating of 40VA. The unit utilizes an epoxy resin encapsulation process to ensure mechanical stability and environmental protection against moisture and contaminants. Electrical isolation between the primary and secondary circuits is maintained through reinforced insulation barriers compliant with safety standards. The transformer operates at standard frequencies of 50/60Hz and includes built-in thermal protection mechanisms to prevent overheating during fault conditions or sustained overloads.

Feature Summary

• Dual primary winding configuration allows flexible input voltage selection
• Epoxy encapsulated construction provides robust environmental sealing
• Integrated thermal fuse offers overtemperature protection
• Reinforced insulation ensures safe electrical isolation

Applications

• Industrial control panel power supplies
• Medical equipment internal power systems
• Commercial appliance transformer stages
• Test and measurement instrument power conditioning

Procurement Notes

Verify that the specific part number matches the required electrical specifications before procurement. Confirm that the physical dimensions and pinout configuration are compatible with the target assembly. Ensure that the operating environment temperature range aligns with the component's rated limits. Check for any specific regulatory certifications required by the end product jurisdiction. Validate that the supplier provides genuine components with traceable documentation.

Selection Notes

Select this transformer when a 40VA capacity is sufficient for the load requirements. Consider the dual primary design if input voltage flexibility between 115VAC configurations is needed. Evaluate the physical footprint constraints to ensure the encapsulated package fits within the enclosure. Assess the thermal management capabilities of the host system given the self-heating characteristics. Verify that the secondary voltage regulation meets the sensitivity requirements of the downstream circuitry.

Part Context

This component belongs to the DPC series of general-purpose power transformers manufactured by Signal Transformer. The series is characterized by high reliability and compact form factors suitable for various industrial applications. These transformers are commonly used in scenarios requiring isolated AC power conversion from standard line voltages to lower control voltages. The DPC series emphasizes durability through encapsulation techniques that protect internal windings from mechanical stress and environmental degradation.

Replacement Considerations

Consult official manufacturer cross-reference lists for direct replacements. Verify that any substitute part maintains identical electrical ratings including VA, primary/secondary voltages, and frequency response. Ensure physical compatibility regarding mounting holes, lead lengths, and overall envelope dimensions. Confirm that safety certifications and insulation class ratings meet or exceed original specifications.
