166D20

Overview

The Hammond Manufacturing 166D20 is a laminated core power transformer designed for industrial applications. It features a low voltage configuration with a primary input of 115VAC at 60 Hz. The unit provides a secondary output of 20 Volts Center Tap (C.T.) delivering 0.1 Amperes, resulting in a total power rating of 2 VA. The transformer utilizes a C-style horizontal channel bracket for two-hole chassis mounting. Primary and secondary leads are each 6 inches long to facilitate wiring connections.

Feature Summary

• Laminated core construction for efficient power transformation
• Low voltage operation suitable for control circuits
• Center tap secondary winding configuration
• Chassis mount design with integrated C-style bracket

Applications

• Industrial control panel power supplies
• Low voltage equipment powering
• Electronic circuit protection and isolation

Procurement Notes

Verify the specific lead time requirements with authorized distributors prior to ordering, as production cycles may vary. Confirm that the shipping destination supports the required currency and logistics constraints associated with this component. Ensure all technical specifications align with the target system's electrical and mechanical interface requirements before finalizing procurement.

Selection Notes

Select the 166D20 when a compact, low-voltage power source is required for chassis-mounted installations. This model is appropriate for systems needing 2 VA of isolated power from a standard 115VAC line. Consider the 6-inch lead length for routing convenience and verify that the 20V C.T. output matches the downstream load requirements precisely.

Part Context

This component belongs to Hammond Manufacturing's industrial power transformer series. These transformers are engineered for reliability in demanding environments. The 166D20 specifically addresses the need for small form-factor power conversion in equipment where space is limited but robust electrical isolation is necessary for safety and performance.

Replacement Considerations

Consult official Hammond Manufacturing documentation for verified substitute part numbers. Cross-reference electrical ratings and physical dimensions to ensure compatibility with existing mounting structures and circuit designs.
