160H120

Overview

The Hammond Manufacturing 160H120 is a low voltage power transformer designed for printed circuit board (PCB) mounting. It features a laminated core and split bobbin construction, supporting vertical installation. The unit operates with a primary voltage of 115V or 230V AC at 60Hz. The secondary output provides 120VAC center-tapped configuration, delivering a total apparent power capacity of 24VA. Electrical ratings include 200mA per half-secondary in series connection or 400mA in parallel connection.

Feature Summary

• Vertical PCB mount design with split bobbin construction
• Laminated core structure for efficient power transfer
• Dual primary voltage compatibility for global operation
• Center-tapped secondary winding for flexible circuit integration

Applications

• Low voltage control panel power supplies
• Industrial equipment internal power distribution
• Electronic instrumentation power modules
• Automation system control circuits

Procurement Notes

Verify the specific datasheet revision to confirm pinout orientation and mounting hole dimensions prior to integration. Ensure the input voltage matches the selected primary wiring configuration. Confirm that the enclosure allows for adequate airflow as this is an open-style component. Validate that the PCB layout accommodates the vertical mounting height and terminal spacing requirements specified in the official documentation.

Selection Notes

Select this model when a 24VA capacity is required for 120VAC center-tapped applications. The vertical form factor suits space-constrained PCB layouts where height is available but footprint is limited. Consider the split bobbin design for improved isolation characteristics compared to standard wound transformers. Verify that the operating temperature range aligns with the environmental conditions of the final assembly.

Part Context

This component belongs to the Hammond 160 Series, which covers a range of low voltage PC board mount transformers from 0.5VA to 24VA. The series utilizes a consistent vertical mounting style across different power ratings. The 160H120 represents the highest power option within this specific physical envelope, offering robust performance for demanding industrial applications requiring reliable isolated power conversion.

Replacement Considerations

Direct substitutes must match the 24VA rating, 115/230V primary, and 120VCT secondary specifications. Verify that alternative components maintain the same vertical PCB mounting profile and terminal configuration. Cross-reference mechanical dimensions to ensure fit within existing enclosures. Confirm electrical isolation ratings meet safety standards for the target application.
