Overview
The Hammond Manufacturing 166G80 is a low voltage industrial power transformer designed for chassis mounting. It features a single primary winding rated for 115 VAC at 60 Hz and a center-tapped secondary output of 80 VAC. The unit has a power rating of 40 VA with a secondary current capacity of 0.5 A. Physical dimensions are 3.69 inches in length, 1.88 inches in width, and 2.31 inches in height. It operates within a temperature range of 0°C to +130°C and supports 50/60 Hz frequencies.
Feature Summary
- Chassis mount construction for secure installation
- Low voltage step-down capability
- Center-tapped secondary winding configuration
- Single primary winding design
Applications
- Industrial control panels
- Equipment requiring isolated low voltage power
- Chassis-mounted electronic assemblies
Procurement Notes
Verify the specific voltage and current requirements against the 115V primary and 80V CT secondary specifications. Confirm that the 40 VA rating meets the load demands. Ensure chassis mounting space accommodates the physical dimensions. Check for compliance with relevant regional safety standards before integration.
Selection Notes
Select this model when a 40 VA transformer is required for 115V input systems. The 80V center-tapped output suits applications needing dual polarity or rectified DC sources. Consider the chassis mount style for fixed installations rather than PCB mounting. Evaluate thermal management needs given the operating temperature limits.
Part Context
This component belongs to the Hammond 166 series of industrial power transformers. The series offers various power ratings and voltage configurations. The 166G80 specifically addresses the need for higher voltage outputs compared to lower VA models in the same form factor family.
Replacement Considerations
Direct substitutes include other Hammond 166 series models with matching electrical characteristics. Verify pinout compatibility if replacing existing units. Cross-reference with other manufacturers offering equivalent 40 VA chassis mount transformers with identical dimensions.
