166U7

Overview

The Hammond Manufacturing 166U7 is a low voltage industrial power transformer with an 112.5 VA rating. It features a single primary winding rated for 115 VAC at 50/60 Hz and a single secondary winding providing 7.5 VAC center-tapped output at 15 A. Designed for chassis mounting, it utilizes wire leads for termination. The unit measures 112.5 mm in length, 57.2 mm in width, and 66.8 mm in height, weighing approximately 1.134 kg. It operates within a temperature range of 0°C to +130°C.

Feature Summary

• Chassis mount construction with wire lead terminations
• Single primary and single secondary winding configuration
• Low voltage laminated core design

Applications

• Industrial control panels
• Power supply circuits requiring low voltage AC
• Equipment needing 7.5V center-tapped outputs

Procurement Notes

Verify the specific secondary current requirement of 15A against your load calculations to ensure adequate capacity. Confirm that the chassis mounting style and wire lead termination method are compatible with your assembly process. Check local regulatory compliance requirements such as RoHS status before finalizing procurement orders.

Selection Notes

Select this model when a high-current 7.5V secondary output is required from a standard 115V primary source. Ensure the physical dimensions fit the available chassis space. Consider the thermal management capabilities given the high current rating and operating temperature limits specified by the manufacturer.
