160G20

Overview

The Hammond Manufacturing 160G20 is a low voltage PCB mount power transformer designed for through-hole installation. It features dual primary windings rated for 115 VAC and 230 VAC input, providing flexibility for global voltage standards. The secondary output delivers 20 VAC center-tapped at 500 mA, with a total power rating of 10 VA. This component utilizes a compact form factor suitable for space-constrained circuit board designs.

Feature Summary

• Dual primary winding configuration supports both 115 VAC and 230 VAC input voltages.
• Center-tapped secondary output provides symmetrical voltage distribution.
• Low profile design optimized for direct printed circuit board mounting.

Applications

• Low voltage AC power supply circuits
• Control panel transformer applications
• Electronic equipment requiring isolated secondary voltages

Procurement Notes

Verify the specific secondary current rating against project requirements, as some sources indicate 500 mA while others suggest 180 mA for similar variants. Confirm that the 10 VA power rating aligns with the thermal management capabilities of the target enclosure. Ensure the through-hole footprint matches the PCB layout specifications before finalizing the order.

Selection Notes

Select this model when a compact, board-mounted solution is required for stepping down standard line voltages to lower AC levels. The dual primary feature simplifies inventory management by accommodating different regional mains frequencies without changing hardware. Consider the physical dimensions to ensure adequate clearance on the assembly.

Part Context

This transformer belongs to the 160 series of low voltage PCB mount transformers from Hammond Manufacturing. It shares design characteristics with models like the 160G56 and 162H24, differing primarily in secondary voltage and current ratings. The series is characterized by its robust construction and compliance with industrial safety standards.

Replacement Considerations

The 160G56 serves as a functional substitute if the application can tolerate a higher secondary voltage of 56 VAC CT. For lower current requirements, the 162F20 offers a 20 VAC CT output but with a reduced 300 mA rating and 6 VA power capacity. Verify pin compatibility and mounting hole spacing when swapping between these variants.
