• Automation systems utilizing chassis-mounted transformer configurations

Procurement Notes

Verify the specific secondary current rating and connection method (series vs. parallel) against the application circuit design to ensure adequate capacity. Confirm that the chassis mounting space accommodates the physical dimensions and weight of the toroidal core. Ensure input voltage matches the dual primary winding specifications before installation. Cross-reference the manufacturer datasheet for thermal derating guidelines under continuous load conditions.

Selection Notes

Select this model when a compact, low-noise power source is required for industrial controls. The 225 VA rating suits moderate power loads where efficiency and size are critical. Consider the dual secondary flexibility if multiple voltage rails or higher current availability is needed. Evaluate the chassis mounting style against available panel space and vibration requirements. Compare against other toroidal transformers in the series for alternative voltage configurations.

Part Context

This component belongs to the Hammond 1182 series of toroidal power transformers, known for high efficiency and low profile designs. The series offers a wide range of power ratings and voltage configurations tailored for industrial and commercial applications. These transformers utilize closed-core geometry to reduce external magnetic fields, making them suitable for sensitive electronic environments.
