631C

Overview

The Hammond Manufacturing 631C is a plug-in power transformer designed for industrial applications. It features a primary voltage rating of 115V AC and provides a secondary output of 36V CT (Center Tapped). The unit has a power capacity of 18VA and supports a maximum current of 0.5A. This component utilizes through-hole mounting technology, allowing for secure integration into printed circuit boards or chassis panels. The design ensures reliable electrical isolation and voltage transformation for control circuits requiring stable step-down performance.

Feature Summary

• Provides isolated 36V center-tapped secondary output from standard 115V primary input
• Engineered with 18VA power rating suitable for moderate load control circuits
• Constructed with plug-in form factor for straightforward installation into designated sockets

Applications

• Industrial control panel power supplies
• Machine tool control systems
• Automation equipment interface circuits
• Relay driver power sources

Procurement Notes

Verify the specific pin configuration and socket compatibility before procurement, as plug-in transformers require matching receptacles. Confirm that the 115V primary voltage aligns with your local supply standards. Ensure the 18VA rating meets the peak current demands of the downstream circuitry to prevent saturation or overheating during operation.

Selection Notes

Select this model when a dedicated 36V CT supply is required for bridge rectifier configurations in control logic. Consider the physical dimensions and mounting style to ensure fit within the enclosure. Evaluate thermal management requirements based on the continuous load profile, as the sealed construction relies on ambient cooling for heat dissipation during sustained operation.

Part Context

This component belongs to Hammond Manufacturing's line of industrial power transformers, known for robust construction and compliance with safety standards. The 631C serves as a specialized solution for stepping down mains voltage to lower levels for sensitive control electronics. Its plug-in design distinguishes it from general-purpose wound transformers, offering convenience for modular system architectures.

Replacement Considerations

Direct replacements must match the 115V primary, 36V CT secondary, and 18VA rating. Verify pinout compatibility with existing sockets. Alternative models from other manufacturers may require adapter plates if the footprint differs. Always confirm regulatory certifications such as UL or CSA are maintained for safety compliance in the new substitute.
