Overview
The Hammond Manufacturing 166EA24 is a laminated core power transformer designed for chassis mounting in industrial control applications. It features a single primary winding rated for 115VAC input and a single secondary winding providing 24VAC output with a center tap. The unit has a maximum power rating of 4.8VA and supports a maximum secondary current of 200mA. It operates at frequencies of 50Hz or 60Hz and includes an isolation voltage of 2000VRMS. The physical dimensions are approximately 60.45mm in length, 38.10mm in width, and 35.05mm in height, with wire lead terminations.
Feature Summary
- Chassis mount design with wire lead terminations for direct integration into control panels
- Laminated core construction providing stable low voltage power conversion
- Dual voltage capability via center-tapped secondary winding configuration
Applications
- Industrial control panel power supplies
- Low voltage AC circuit powering
- Equipment requiring isolated 24VAC sources
Procurement Notes
Verify the specific voltage and current requirements against the 115VAC primary and 24VAC/200mA secondary ratings before ordering. Confirm that the chassis mounting style and wire lead termination method align with the assembly design. Ensure the operating environment remains within the specified temperature range to maintain performance and safety standards.
Selection Notes
Select this model when a compact, low-voltage transformer is needed for chassis installation. The 4.8VA rating suits light-duty control circuits. Consider the dual primary options in other series if 230VAC input compatibility is required instead of the standard 115VAC configuration found in this specific part number.
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 automation needs. The 166EA24 specifically addresses applications requiring a 24VAC output from a standard 115VAC source in a compact form factor.
Replacement Considerations
For equivalent specifications, consider the Hammond 166G16 which provides a similar chassis-mount design but differs in power rating and secondary voltage. Verify dimensional constraints and electrical parameters carefully when substituting components to ensure system compatibility.
