Overview
The Hammond Manufacturing 166J33 is a low voltage industrial power transformer with a 33 VA rating. It features a single primary winding rated for 115 VAC and a single secondary winding providing 33 VAC center-tapped output at 1 A. Designed for chassis mounting, it utilizes wire leads for connection. The unit operates within a temperature range of 0°C to +130°C and supports frequencies of 50 Hz or 60 Hz. Physical dimensions are approximately 82.55 mm in length, 50.80 mm in width, and 50.80 mm in height.
Feature Summary
- Provides isolated power conversion from standard line voltage to lower control voltages
- Features a laminated core construction for efficient magnetic flux transfer
- Includes a center-tapped secondary winding configuration for dual polarity applications
Applications
- Industrial control panels requiring low voltage power distribution
- Equipment housing needing chassis-mounted isolation transformers
- Control circuits utilizing center-tapped rectification supplies
Procurement Notes
Verify the specific secondary voltage and current requirements against the 33V AC CT specification 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 thermal limits to maintain performance integrity.
Selection Notes
Select this component when a 33 VA capacity is required for 115 VAC input systems. Consider the physical footprint constraints as the unit measures roughly 82.55 mm by 50.80 mm. Evaluate the need for a center-tapped output versus a standard secondary configuration to ensure compatibility with downstream circuitry.
Part Context
This model belongs to the Hammond 166 series of industrial control transformers. The series offers various power ratings and voltage configurations tailored for general industrial applications. These units are characterized by their robust construction and standardized mounting options suitable for integration into larger electrical enclosures.
Replacement Considerations
Consult official cross-reference data for direct substitutes. Verify that any alternative part matches the 33 VA rating, 115 VAC primary, and 33 VAC CT secondary specifications to ensure functional equivalence.
