166G30

Overview

The Hammond Manufacturing 166G30 is a low voltage industrial power transformer with a 15 VA rating. It features a single primary winding rated for 115 VAC at 60 Hz and a single secondary winding providing 30 VAC center-tapped output at 0.5 A. Designed for chassis mounting, the unit utilizes wire leads for termination. The transformer operates within a temperature range of 0°C to +130°C and supports frequencies of 50 Hz or 60 Hz. Physical dimensions are 82.55 mm in length, 41.4 mm in width, and 50.8 mm in height, weighing approximately 408 g.

Feature Summary

• Single primary and single secondary winding configuration for standard isolation applications
• Center-tapped secondary output design facilitating dual polarity power supply circuits
• Chassis mount style with wire lead terminations for direct integration into control panels

Applications

• Industrial control panel power distribution
• Low voltage equipment power supplies
• Electronic instrumentation power conditioning

Procurement Notes

Verify that the incoming component matches the 166G30 designation and confirms the 15 VA power rating alongside the 115 VAC primary and 30 VAC CT secondary specifications. Ensure the physical chassis mounting footprint aligns with the specified dimensions of 82.55 mm by 41.4 mm by 50.8 mm. Confirm that wire lead terminations are intact and suitable for the intended circuit connections before installation.

Selection Notes

Select this transformer when a compact 15 VA solution is required for stepping down 115 VAC mains to a lower voltage. The center-tapped secondary is essential for applications requiring split-rail DC conversion or specific AC control signals. Consider the chassis mounting requirement and wire lead termination style during system design to ensure proper mechanical integration and electrical connectivity within the enclosure.

Part Context

This component belongs to the Hammond Manufacturing 166 series of industrial control transformers. These units are engineered for general-purpose power transformation in industrial environments. The series offers various voltage and wattage combinations, with the 166G30 specifically addressing needs for moderate power isolation at low voltages using a standard 115 VAC input.

Replacement Considerations

Cross-reference part numbers such as 166J33 for alternative voltage configurations within the same series. Verify that any substitute maintains the 15 VA rating and compatible mounting dimensions to ensure seamless replacement without modifying the existing chassis layout or wiring harness.
