167L12

Overview

The Hammond Manufacturing 167L12 is a low voltage filament power transformer designed for industrial control applications. It features a single primary winding rated at 115 VAC and a single secondary winding providing 12.6 VAC center-tapped output. The unit has a power rating of 31.5 VA with a secondary current capacity of 2.5 A. It utilizes wire leads for termination and is constructed for chassis mounting. The transformer operates at 50 Hz or 60 Hz frequencies and supports an operating temperature range from 0°C to +130°C.

Feature Summary

• Enclosed chassis mount construction with four mounting holes
• Single primary winding configuration for standard 115 VAC input
• Center-tapped secondary winding design suitable for filament applications
• Minimum six-inch long wire leads for flexible connection

Applications

• Industrial control panel power supplies
• Filament heating circuits in electronic equipment
• Low voltage AC power distribution systems
• Chassis-mounted instrumentation power sources

Procurement Notes

Verify the specific datasheet version for the 167L12 model to confirm exact dimensional tolerances and lead wire specifications. Ensure that the procurement documentation explicitly states compliance with relevant safety standards for industrial transformers. Cross-reference the manufacturer's part number against authorized distributor lists to guarantee authenticity. Confirm that the received units match the 31.5 VA rating and 12.6 VCT output requirements before integration into final assemblies.

Selection Notes

Select the 167L12 when a compact, enclosed transformer is required for 115 VAC to 12.6 VCT conversion. This model is appropriate for applications needing 2.5 A continuous current from a center-tapped source. Consider this option if chassis mounting with wire leads is preferred over PCB mounting. Evaluate thermal management needs given the 130°C maximum operating temperature limit. Compare physical dimensions against available panel space to ensure proper fit within the enclosure design constraints.

Part Context

The 167L12 belongs to the Hammond Manufacturing 167 series of low voltage filament transformers. This series provides various power ratings and voltage configurations for industrial use. Similar models in the series include the 167L16 and 167L20, which offer different secondary voltages while maintaining similar chassis mount characteristics. The 167 series is distinct from the 166 series, which may feature different enclosure styles or mounting options. All units in this family share common design principles for reliability in control environments.

Replacement Considerations

Direct substitutes within the same series include the 167L16 and 167L20, though these differ in secondary voltage ratings. Verify that any replacement maintains the 115 VAC primary requirement and chassis mount form factor. Ensure the alternative component meets or exceeds the 31.5 VA power rating and 2.5 A current capacity. Check dimensional compatibility to guarantee fit within existing mounting structures.
