LP-30-800

Power Transformers Overview

The LP-30-800 is a low-profile, semi-toroidal power transformer from the Signal Transformer LP series. It features dual primary windings rated for 115 VAC and 230 VAC operation at 50/60 Hz. The secondary configuration provides dual outputs: 15 VAC at 1.6 A in parallel mode, or 30 VAC center-tapped at 800 mA in series mode. With a 24 VA power rating, it utilizes through-hole mounting and measures 47.5 mm in length, 39.6 mm in width, and 21.6 mm in height.

Power Transformers Feature Summary

• Semi-toroidal hum-bucking construction reduces electromagnetic interference
• Dual primary winding design supports global voltage compatibility
• Low-profile flat head form factor enables compact board integration

Power Transformers Applications

• Servo drive power supplies
• Industrial control systems
• General purpose AC to DC conversion circuits

Power Transformers Procurement Notes

Verify that the specific order matches the required secondary configuration (parallel vs. series) as the component supports both via internal winding connections. Confirm lead times with authorized distributors, as availability may vary. Ensure PCB layout accommodates the specified through-hole pin spacing and physical dimensions to prevent mechanical interference during assembly.

Power Transformers Selection Notes

Select this model when a compact, low-noise transformer is required for 24 VA applications. The semi-toroidal design offers superior noise performance compared to standard laminated transformers. Choose this part if space constraints necessitate a low-profile package while maintaining high efficiency and thermal stability under continuous load conditions.

Power Transformers Part Context

This component belongs to the LP series of low-profile power transformers manufactured by Signal Transformer. The series is characterized by its flat head design and semi-toroidal core construction, which distinguishes it from traditional EI-laminated transformers. These units are designed for board-mount applications where size and acoustic noise are critical factors.

Power Transformers Replacement Considerations

Direct replacements must match the 24 VA rating, 115/230 VAC primary input, and compatible secondary voltage/current specifications. Verify that substitute components maintain the same through-hole footprint and height constraints to ensure mechanical compatibility within the existing enclosure.
