166L2

Overview

The Hammond Manufacturing 166L2 is a laminated core power transformer designed for industrial control applications. It features a single primary winding rated at 115 VAC and a single secondary winding providing 2.5 VAC with center tap functionality. The unit has a maximum power rating of 6.25 VA and supports a secondary current of 2.5 A. Physical dimensions are 71.38 mm in length, 38.10 mm in width, and 42.93 mm in height. It utilizes wire leads for termination and is intended for chassis mounting.

Feature Summary

• Single primary winding configuration for standard 115 VAC input
• Center-tapped secondary output for low voltage applications
• Chassis mount design with horizontal channel bracket compatibility
• Laminated core construction for efficient power transformation

Applications

• Industrial control panels requiring low voltage power
• Equipment needing 2.5 VAC center-tapped supply
• Chassis-mounted electronic enclosures
• General purpose industrial transformers

Procurement Notes

Verify the specific secondary voltage and current requirements against the 2.5 VAC / 2.5 A specifications before ordering. Confirm that the chassis mounting style and wire lead termination match the assembly design. Ensure the operating environment falls within the standard temperature range. Cross-reference the physical dimensions to guarantee fitment within the target enclosure space.

Selection Notes

Select this model when a low voltage, center-tapped secondary is required for industrial control circuits. The 6.25 VA rating suits light-duty applications. Consider the chassis mount style and wire leads for integration. Compare with other 166 series variants if different voltages or power ratings are needed. Verify insulation and safety compliance for the intended region.
