Overview
The Hammond Manufacturing 1182Q9 is an industrial toroidal power transformer with an 80 VA rating. It features dual primary windings supporting 115 VAC and 230 VAC inputs, and dual secondary windings configured for 18 VAC series or 9 VAC parallel outputs at a maximum current of 4.44 A. Designed for chassis mounting with wire leads, it operates at 50 Hz/60 Hz frequencies.
Feature Summary
- Toroidal core construction provides low stray magnetic flux leakage and reduced electromagnetic interference.
- Dual primary and secondary winding configurations allow flexible voltage input and output selection.
- Chassis mount design facilitates integration into industrial control enclosures.
Applications
- Industrial control systems requiring isolated power supplies
- Electronic equipment needing low-noise AC power conversion
- General purpose power transformation in manufacturing environments
Procurement Notes
Verify the specific part number suffix against official Hammond Manufacturing documentation to confirm exact electrical ratings and physical dimensions. Ensure compatibility with existing chassis mounting hardware and wire lead termination requirements before procurement.
Selection Notes
Select this model when an 80 VA toroidal transformer with dual voltage flexibility is required. Confirm that the 9 VAC parallel secondary configuration meets load current demands of up to 4.44 A. Verify chassis space constraints align with the component's physical height and diameter specifications.
Part Context
Part of the 1182 series of toroidal transformers from Hammond Manufacturing, designed for industrial applications. This series emphasizes compact size, high efficiency, and low electromagnetic interference through its core geometry.
Replacement Considerations
Consult official Hammond Manufacturing cross-reference lists for verified substitutes. Do not assume generic toroidal transformers are compatible without verifying electrical ratings and mounting dimensions.
