10-250-LPI

Overview

The Signal Transformer 10-250-LPI is a board-mount power transformer designed for 50/60 Hz applications. It features a laminated core construction with encapsulation for environmental protection. The unit supports dual primary windings configured in parallel for 115V or 230V input operation. Secondary outputs provide 5VAC at 500mA and 10VAC at 250mA, also connected in parallel. This component utilizes through-hole mounting technology for secure PCB integration.

Feature Summary

• Dual primary winding configuration allows flexible voltage selection between 115V and 230V inputs via parallel connection.
• Encapsulated laminated core design provides mechanical stability and environmental protection for the magnetic assembly.

Applications

• Low-power electronic equipment requiring isolated AC voltage conversion
• Control circuits utilizing multiple secondary voltage taps
• Industrial control panels with standard line frequency requirements

Procurement Notes

Verify that the specific lot code matches the manufacturer's current production standards. Confirm that the encapsulation integrity remains intact during shipping to prevent damage to the laminated core structure. Ensure that the through-hole pin spacing aligns precisely with the target printed circuit board layout before finalizing the purchase order.

Selection Notes

Select this component when a compact, encapsulated solution is required for low-voltage secondary outputs. The dual primary design offers flexibility for global voltage compatibility without rewinding. Ensure the total load does not exceed the specified 2.5 VA rating to maintain thermal performance and efficiency within safe operating limits.

Part Context

This part belongs to the Signal Transformer series of general-purpose power transformers. It is characterized by its small form factor and robust encapsulation. The model number indicates a 2.5 VA power rating, distinguishing it from higher-capacity industrial units in the broader product portfolio.

Replacement Considerations

Direct substitutes must match the 2.5 VA rating, 50/60 Hz frequency, and identical pinout configuration. Verify that any alternative component maintains the same encapsulation type and through-hole mounting dimensions to ensure physical compatibility.
