Overview
The Hammond Manufacturing 166F10 is a low voltage industrial power transformer designed for chassis mounting. It features a single primary winding rated at 115 VAC and a center-tapped secondary output of 10 VAC. The unit has a power rating of 3 VA with a maximum secondary current of 0.3 A. Operating at 50/60 Hz, it utilizes wire leads for termination. The physical dimensions are approximately 60.45 mm in length, 35.05 mm in width, and 35.05 mm in height, weighing roughly 181 g.
Feature Summary
- Chassis mount construction with wire lead terminations
- Single primary and single center-tapped secondary winding configuration
- Low voltage operation suitable for industrial control applications
Applications
- Industrial control panels
- Equipment requiring low voltage AC power
- Control circuit isolation
Procurement Notes
Verify the manufacturer part number 166F10 against official Hammond Manufacturing documentation to ensure correct specifications. Confirm that the required voltage, current, and mounting style match the application needs. Check for RoHS compliance status in the latest datasheet. Ensure wire lead lengths and terminal types are compatible with the assembly design before ordering.
Selection Notes
Select this component when a compact, low-power transformer is needed for chassis installation. The 3 VA rating limits its use to small control circuits rather than high-power loads. Consider the center-tapped secondary if rectification or split-rail supplies are required. Verify that the 115 VAC primary input matches the available supply voltage and frequency.
Part Context
This model belongs to the Hammond 166 series of industrial power transformers. The series offers various voltage and wattage combinations for different control requirements. These units are generally characterized by their laminated core construction and open-style design intended for internal equipment mounting.
Replacement Considerations
Direct substitutes may include other Hammond 166 series variants with matching electrical ratings. Cross-reference with other manufacturers offering similar 3 VA, 115V primary, 10V CT secondary transformers. Ensure mechanical footprint and lead configuration compatibility when considering alternative brands.
