Overview
The Hammond Manufacturing 166P18 is a low voltage industrial power transformer featuring a laminated core and chassis mount style. It operates at 50/60 Hz with a primary voltage of 115 VAC. The unit provides an 18 VAC center-tapped secondary output capable of delivering 5 A current, resulting in a 90 VA power rating. Physical dimensions are 4.03 inches in length, 2.50 inches in width, and 2.63 inches in height. It utilizes wire leads for termination and functions within a temperature range of 0°C to +130°C.
Feature Summary
- Laminated core construction for efficient power transformation
- Chassis mounting design for secure installation
- Single primary winding configuration
- Center-tapped secondary output capability
Applications
- Industrial control panels
- Low voltage power supply systems
- Equipment requiring isolated AC power sources
Procurement Notes
Verify the specific part number against official Hammond Manufacturing documentation to confirm electrical ratings and physical dimensions. Ensure compatibility with existing chassis mounting points and wiring configurations. Confirm that the operating environment temperature falls within the specified range. Check for any regional compliance requirements such as RoHS status before finalizing procurement decisions.
Selection Notes
Select this component when a 90 VA capacity is required for 115 VAC input applications. The 18 VAC center-tapped output suits circuits needing dual polarity or rectified DC conversion. Consider the chassis mount style and wire lead termination method during system integration planning. Verify spatial constraints match the specified external dimensions.
Part Context
This transformer belongs to the Hammond 166 series of industrial control transformers. The series offers various power ratings and voltage configurations to meet diverse industrial needs. The 166P18 specifically addresses higher current demands compared to lower VA rated models in the same family.
Replacement Considerations
Consult official Hammond Manufacturing substitution guides for verified equivalent parts. Ensure any replacement matches the 90 VA rating, 115 VAC primary, and 18 VAC CT secondary specifications. Verify dimensional compatibility for chassis mounting.
