30-600-LPI

Power Transformers Overview

The Signal Transformer 30-600-LPI is a semi-toroidal power transformer with an 18 VA rating. It features dual primary windings supporting 115 VAC and 230 VAC inputs in parallel configuration. The secondary provides a center-tapped output of 30 VCT at 600 mA or two 15 V outputs at 1.2 A each. Designed for through-hole mounting, it utilizes wire leads for termination. The component measures approximately 47.2 mm in length, 39.4 mm in width, and 38.1 mm in height.

Power Transformers Feature Summary

• Semi-toroidal core construction for efficient magnetic coupling
• Dual primary winding capability for international voltage compatibility
• Center-tapped secondary design allowing flexible voltage configurations
• Through-hole wire lead termination for standard PCB integration

Power Transformers Applications

• General purpose AC power supply circuits
• Industrial control equipment power stages
• Audio amplifier power distribution
• Electronic test and measurement instrumentation

Power Transformers Procurement Notes

Verify the specific datasheet version to confirm insulation class and safety certifications such as UL or CE. Ensure the operating temperature range aligns with your system requirements. Confirm that the wire lead gauge matches your PCB hole specifications. Check for any regional compliance markings required for your target market. Validate the physical footprint against your mechanical constraints before finalizing the order.

Power Transformers Selection Notes

Select this model when an 18 VA capacity is sufficient for the load. Choose the parallel primary configuration for single-voltage regions like North America or Europe. Opt for the center-tapped secondary if bipolar rails or split-phase rectification are needed. Consider the through-hole form factor if surface-mount alternatives are unavailable. Evaluate the thermal performance under maximum load conditions to ensure reliability.

Power Transformers Part Context

This component belongs to the 30-series semi-toroidal transformers from Signal Transformer. These units are designed for general-purpose applications requiring compact size and moderate power handling. The series offers various voltage combinations to suit different global input standards. They are commonly used in consumer electronics and industrial devices where space efficiency is critical.

Power Transformers Replacement Considerations

Direct substitutes must match the 18 VA rating, 30 VCT secondary, and through-hole wire lead format. Verify that alternative parts support the same 115/230 VAC primary voltages. Ensure the physical dimensions fit within the existing enclosure or PCB layout. Check that the replacement part meets the same safety and regulatory standards.
