166L18

Overview

The Hammond Manufacturing 166L18 is a low voltage industrial power transformer designed for chassis mounting. It features a single primary winding rated at 115 VAC and operates at 50 Hz or 60 Hz frequencies. The unit delivers a secondary output of 18 VAC center-tapped with a current rating of 2 A, providing a total power capacity of 36 VA. Physical dimensions are 3.25 inches in length, 2 inches in width, and 2 inches in height, weighing approximately 589.67 grams. It utilizes wire leads for termination and supports an operating temperature range from 0 C to +130 C.

Feature Summary

• Chassis mount construction for secure panel installation
• Single primary and single secondary winding configuration
• Low voltage laminated core design for efficient power conversion
• Wire lead termination for direct circuit integration

Applications

• Industrial control panels requiring low voltage power distribution
• Equipment needing 18V AC center-tapped supply for rectification
• General purpose machinery control circuits
• Automation systems utilizing standard 115V AC input

Procurement Notes

Verify the specific secondary current requirement matches the 2A rating before procurement. Confirm that the chassis mounting style and wire lead termination are compatible with the target enclosure design. Ensure the operating environment stays within the specified 0 C to +130 C temperature range. Check for any regional compliance requirements regarding RoHS standards. Validate that the physical dimensions fit the available space in the assembly.

Selection Notes

Select this model when a 36 VA capacity is required for 115V primary applications. Choose the 166L18 over lower wattage variants if the load exceeds 1A on the 18V secondary side. Consider the chassis mount style if panel mounting is preferred over PCB or DIN rail options. Verify that the center-tapped secondary configuration aligns with the downstream rectifier or bridge circuit design requirements.

Part Context

This component belongs to the Hammond 166 series of industrial control transformers. The series offers various power ratings and voltage configurations tailored for different industrial needs. The 166L18 specifically addresses applications requiring higher current output compared to lower VA models like the 166G8 or 166G16. It shares the same chassis mount form factor and wire lead termination style as other units in the family.
