LP-12-450

Power Transformers Overview

The Signal Transformer LP-12-450 is a semi-toroidal power transformer with a 6VA rating. It features dual primary windings for 115V and 230V parallel operation. The secondary provides dual outputs: 6.3V at 900mA in parallel and 12.6V at 450mA in series. Designed for through-hole mounting, it measures 47.5mm in length and 39.6mm in width. The unit weighs approximately 198.67g and utilizes hum-bucking construction to minimize electromagnetic interference.

Power Transformers Feature Summary

• Semi-toroidal hum-bucking construction reduces magnetic interference
• Dual primary winding configuration supports multiple input voltages
• Dual secondary winding allows flexible voltage and current configurations

Power Transformers Applications

• Servo power supply systems
• Industrial control equipment requiring stable low-voltage DC
• Audio amplifiers utilizing hum-bucking transformers

Power Transformers Procurement Notes

Verify the specific ordering suffix matches the required secondary configuration (parallel vs. series) as indicated in official datasheets. Confirm that the through-hole package dimensions align with the target PCB layout. Ensure the 6VA power rating meets the load requirements of the intended circuit application before finalizing procurement.

Power Transformers Selection Notes

Select this component when a compact, low-interference power source is needed for servo or audio applications. The dual secondary design offers flexibility for different voltage rails. Consider the physical size constraints due to the semi-toroidal shape and ensure adequate clearance for the through-hole leads during assembly.

Power Transformers Part Context

This part belongs to the LP series of servo power transformers from Signal Transformer. These units are characterized by their semi-toroidal geometry, which distinguishes them from standard laminated core transformers. The series is designed for applications where space efficiency and reduced hum are critical performance factors.

Power Transformers Replacement Considerations

Consult official cross-reference lists for direct substitutes. Verify that any replacement maintains the same 6VA rating, primary voltage compatibility, and secondary output specifications to ensure circuit integrity.
