166C50

Overview

The Hammond Manufacturing 166C50 is a low voltage industrial control power transformer designed for chassis mounting. It features a single primary winding rated for 115 VAC input and a single secondary winding providing 50 VAC center-tapped output. The unit has a power rating of 3.75 VA with a secondary current capacity of 75 mA. Constructed with a laminated core, it supports operation at 50 Hz or 60 Hz frequencies within an ambient temperature range of 0°C to +130°C. Physical dimensions are approximately 82.55 mm in length, 50.8 mm in width, and 50.8 mm in height, utilizing wire leads for termination.

Feature Summary

• Provides isolated low voltage AC power conversion from standard line voltage for control circuits
• Features a robust laminated core construction for stable electromagnetic performance
• Designed for secure chassis mounting with integrated wire lead terminations

Applications

• Industrial control panel power supplies
• Machine tool electrical systems
• Automation equipment control circuits

Procurement Notes

Verify the specific part number 166C50 against official Hammond Manufacturing documentation to confirm the 3.75 VA rating and 50V CT secondary specifications. Ensure that the required 115V primary input matches your system voltage. Confirm chassis mounting compatibility and wire lead termination requirements before procurement to avoid integration issues.

Selection Notes

Select this component when a compact, low-power isolation transformer is needed for 115V to 50V center-tapped applications. Consider the 3.75 VA limit to ensure the load does not exceed 75 mA. Evaluate the physical footprint constraints against the specified dimensions and verify thermal management capabilities given the maximum operating temperature of +130°C.

Part Context

This model belongs to the Hammond 166 series of industrial control transformers. The series offers various power ratings and voltage configurations tailored for general-purpose industrial applications. The 166C50 represents a lower power variant within this lineup, suitable for smaller control modules requiring reliable voltage step-down and isolation.

Replacement Considerations

Cross-reference with other Hammond 166 series models such as 166G60 or 166L50 if higher power ratings are acceptable. Verify that substitute parts match the exact 50V CT secondary specification and 115V primary requirement to maintain circuit functionality.
