167M18

Overview

The Hammond Manufacturing 167M18 is a low voltage, enclosed chassis mount power transformer with a 54 VA rating. It features a single primary winding rated at 115 VAC and a single secondary winding providing 18 VAC center-tapped output. The unit supports a maximum secondary current of 3 A and operates at 50 Hz or 60 Hz frequencies. Physical dimensions are approximately 55.6 mm in length, 66.8 mm in width, and 66.8 mm in height. It utilizes wire leads for termination and is designed for industrial control applications within a temperature range of 0°C to +130°C.

Feature Summary

• Enclosed laminated core construction for safety and noise reduction
• Chassis mounting design with four-hole base configuration
• Center-tapped secondary winding for filament or rectifier circuits
• Long wire leads facilitate flexible installation connections

Applications

• Industrial control panel power supplies
• Filament heating circuits for vacuum tubes
• Rectifier input stages for low voltage DC conversion
• Enclosed equipment internal power distribution

Procurement Notes

Verify the specific part number suffix against official Hammond Manufacturing documentation to confirm exact electrical ratings and lead configurations. Ensure the enclosure type matches the application requirements for thermal management. Confirm that the chassis mounting hole pattern aligns with the existing panel layout before procurement.

Selection Notes

Select this component when a 54 VA capacity is required for 115 VAC to 18 VAC CT conversion. Consider the enclosed chassis mount style for environments requiring physical protection and reduced electromagnetic interference. Evaluate the wire lead length against available routing space within the equipment enclosure.

Part Context

This transformer belongs to the Hammond 167 series, which provides various power ratings for industrial applications. The 167M18 specifically addresses needs for moderate power levels with center-tapped outputs. It is distinct from higher wattage models like the 167P18 or lower wattage variants within the same product family.
