LP-40-600

Power Transformers Overview

The LP-40-600 is a semi-toroidal power transformer from the LP series, designed for low-height PCB applications. It features a dual primary winding configuration supporting 115 VAC and 230 VAC inputs. The secondary output provides 20 VAC at 1.2 A in parallel mode or 40 VAC at 600 mA in series mode. With a 24 VA power rating, it utilizes through-hole mounting and PC pin termination. The unit employs hum-bucking construction to minimize electromagnetic interference.

Power Transformers Feature Summary

• Semi-toroidal hum-bucking construction reduces magnetic noise
• Dual primary windings enable universal voltage compatibility
• Configurable secondary outputs support parallel or series connection modes

Power Transformers Applications

• Low-profile printed circuit board assemblies
• General purpose AC power supply circuits
• Industrial control equipment requiring compact transformers

Power Transformers Procurement Notes

Verify that the specific order matches the LP-40-600 part number to ensure correct secondary voltage configurations. Confirm that the receiving facility accepts through-hole components with PC pin terminations. Check that the application environment does not exceed the thermal limits associated with the 24 VA rating. Ensure proper handling procedures are followed for laminated core components during installation.

Power Transformers Selection Notes

Select this component when space constraints require a low-height transformer profile. Choose this model if the design requires flexible secondary voltage options via series or parallel winding connections. Consider this part for applications needing reduced electromagnetic interference due to its semi-toroidal design. Ensure the load current requirements align with the specified 1.2 A parallel or 600 mA series ratings.

Power Transformers Part Context

This transformer belongs to the LP series, which specializes in ultra-compact power solutions for PCB mounting. The series utilizes semi-toroidal geometry to balance size reduction with performance. It serves as a standard component for replacing bulkier laminated transformers in modern electronic designs where height is a critical constraint.

Power Transformers Replacement Considerations

Direct substitutes must match the 24 VA rating, 115/230 VAC primary input, and identical secondary voltage/current configurations. Verify that replacement units maintain the same physical dimensions and PC pin spacing to fit existing footprints. Ensure the alternative component also supports the required hum-bucking characteristics if EMI sensitivity is present.
