165S12

Overview

The Hammond Manufacturing 165S12 is an industrial power transformer designed for chassis mounting. It features a single primary winding rated at 115 VAC and a single secondary winding providing 12.6 VAC center-tapped output. The unit delivers a maximum secondary current of 10 A with a total power rating of 126 VA. Operating at a frequency of 60 Hz, the transformer supports an ambient temperature range from 0°C to +130°C. Physical dimensions are approximately 3.75 inches in length, 3.13 inches in width, and 3.63 inches in height, with a weight of roughly 1.8 kg.

Feature Summary

• Chassis mount construction for secure panel installation
• Low voltage high current capability for demanding loads
• Center-tapped secondary winding configuration
• Industrial grade thermal performance up to 130°C

Applications

• Industrial control panels requiring isolated low voltage power
• Equipment needing 12.6V CT supply for rectification circuits
• Heavy duty machinery control systems
• Power distribution within industrial enclosures

Procurement Notes

Verify that the specific order matches the 165S12 designation to ensure correct voltage and current ratings. Confirm chassis mounting compatibility with the target enclosure design. Check for RoHS compliance requirements if applicable to the end product. Ensure input voltage matches the 115 VAC primary specification before integration into the system.

Selection Notes

Select this model when a 126 VA capacity is sufficient for the load. The 12.6 VCT secondary is suitable for applications requiring full-wave rectification or split rail supplies. Consider the physical footprint and weight constraints during mechanical design. Verify that the operating environment stays within the specified temperature limits to maintain reliability.

Part Context

This component belongs to the Hammond 165 series of industrial control transformers. The series offers various power ratings and voltage configurations tailored for general industrial use. These units are characterized by robust construction and standardized mounting patterns, facilitating easy replacement and integration into existing industrial infrastructure designs.

Replacement Considerations

Direct substitutes must match the 126 VA rating, 115 VAC primary, and 12.6 VCT secondary specifications. Verify that alternative models support the same chassis mounting style and physical dimensions. Ensure equivalent thermal class and frequency operation to maintain system performance and safety standards.
