LP-40-1200

Power Transformers Overview

The LP-40-1200 is a semi-toroidal power transformer designed for industrial control applications. It features a laminated core construction with dual primary windings rated for 115 VAC and 230 VAC operation in parallel configuration. The secondary winding provides split voltage outputs of 20 VAC and 40 VAC, supporting series or parallel connections. Rated at 48 VA, the unit operates at 50 Hz or 60 Hz frequencies. It utilizes through-hole mounting with quick-connect terminals and measures approximately 82.6 mm in length, 44.3 mm in width, and 49.8 mm in height.

Power Transformers Feature Summary

• Semi-toroidal laminated core design for efficient magnetic coupling
• Dual primary winding capability for flexible input voltage selection
• Split secondary output configuration for versatile circuit integration
• Chassis-mountable form factor with quick-connect termination

Power Transformers Applications

• Industrial control panel power supplies
• Equipment requiring isolated AC power distribution
• Control circuits needing multiple secondary voltage taps
• General purpose AC to AC transformation in machinery

Power Transformers Procurement Notes

Verify the specific datasheet version to confirm terminal pinout and insulation class requirements before integration. Ensure that the operating environment temperature remains within the specified range to maintain performance integrity. Cross-reference the physical dimensions against the enclosure design to guarantee proper fitment. Confirm that the load current does not exceed the rated capacity to prevent thermal overload during continuous operation.

Power Transformers Selection Notes

Select this component when a compact semi-toroidal form factor is required alongside standard 115V or 230V input availability. The split secondary output is suitable for applications needing both lower and higher voltage rails from a single source. Consider the through-hole mounting style if PCB space allows for chassis-style installation. Evaluate the 48 VA rating against the total system load to ensure adequate headroom for transient currents.

Power Transformers Part Context

This part belongs to the LP series of power transformers manufactured by Signal Transformer. The series is characterized by semi-toroidal laminated cores, offering a balance between size efficiency and cost-effectiveness compared to full toroidal designs. These units are commonly used in general-purpose industrial electronics where reliable isolation and standard voltage transformations are necessary.

Power Transformers Replacement Considerations

Direct substitutes may include other 48 VA semi-toroidal transformers with matching 115/230V primary and 20/40V secondary ratings. Verify that alternative parts match the physical footprint and terminal type to ensure compatibility with existing assembly processes.
