1182Q117

Overview

The Hammond Manufacturing 1182Q117 is a toroidal power transformer from the 1182 series, rated at 750 VA. It features dual primary windings supporting 115 VAC and 230 VAC inputs, and dual secondary windings configured for 117 VAC parallel operation or 234 VAC series operation. The unit delivers a secondary current of 6.42 A at 117 VAC. Designed for chassis mounting with wire leads, it operates at 50 Hz/60 Hz frequencies. The transformer has a height of 2.38 inches and weighs approximately 5.897 kg.

Feature Summary

• Toroidal core construction provides low stray magnetic flux leakage and reduced electromagnetic interference.
• Dual primary and secondary windings allow flexible voltage configuration for different input and output requirements.
• Chassis mount design facilitates integration into industrial control panels and equipment enclosures.

Applications

• Industrial control systems requiring isolated power supply
• Audio equipment power stages needing low noise transformers
• Medical device internal power distribution
• Test and measurement instrument power conditioning

Procurement Notes

Verify the specific voltage configuration required (parallel vs. series) against the application schematic before ordering. Confirm that the chassis mounting dimensions and wire lead lengths are compatible with the enclosure design. Ensure the ambient operating temperature range aligns with the transformer's thermal rating to prevent overheating during continuous operation.

Selection Notes

Select this model when a 750 VA capacity is needed with a 117 VAC secondary output. Consider the 1182 series characteristics such as low profile and high efficiency if space constraints exist. Compare weight and physical dimensions against alternative mounting styles if panel space is limited. Verify compatibility with existing wiring harnesses due to the wire lead termination type.

Part Context

The 1182Q117 belongs to Hammond Manufacturing's 1182 series of toroidal power transformers. This series is known for high efficiency and compact design. Other models in the series vary by power rating and voltage configurations, offering options from lower VA ratings up to higher capacities like the 1182T117P. The series shares common design features including dual winding flexibility and chassis mounting.

Replacement Considerations

Direct substitutes within the same series include models with similar VA ratings and voltage outputs, such as the 1182J117 for lower power needs or other 1182 variants. Verify that any replacement matches the physical footprint, mounting hole pattern, and electrical specifications exactly to ensure seamless integration without modifying the enclosure.
