1182P12

Overview

The Hammond Manufacturing 1182P12 is a toroidal power transformer designed for industrial control applications. It features a 120 VA power rating with dual primary windings supporting 115 VAC and 230 VAC inputs at 50 Hz/60 Hz frequencies. The secondary configuration provides an 8-terminal wire lead connection, delivering 4000 VAC output. This chassis-mount component utilizes a single-hole mounting style and includes dual secondary windings to facilitate flexible high-voltage connections.

Feature Summary

• High-voltage isolation capability via 4000 VAC secondary output
• Dual primary winding design for versatile input voltage compatibility
• Toroidal core construction for efficient magnetic flux containment
• Chassis mounting style with eight terminal wire leads

Applications

• Industrial control systems requiring isolated high-voltage supplies
• Medical equipment utilizing line isolation transformers
• Test and measurement instrumentation needing precise voltage steps
• Specialized electronic circuits demanding galvanic separation

Procurement Notes

Verify the specific pinout configuration against the official datasheet before integration, as the eight-terminal layout requires precise wiring alignment. Confirm that the 4000 VAC insulation rating meets the safety standards of the target application environment. Ensure mechanical clearance accommodates the chassis mount dimensions and wire lead lengths specified in the dimensional drawings.

Selection Notes

Select this model when a high-voltage secondary output is required within the 120 VA power class. The dual primary winding allows operation across standard global line voltages without external switching. Consider the physical height and weight constraints relative to other series variants if space is limited. Validate that the wire lead termination method suits the existing PCB or terminal block infrastructure.
