166MS

Overview

The Hammond Manufacturing 166MS is a laminated core power transformer designed for chassis mounting. It features a single primary winding rated at 115V and a single secondary winding providing 5V at 3A, delivering a maximum power of 15VA. The unit includes a center tap on the secondary side and utilizes wire lead termination. Key electrical specifications include an isolation voltage of 2000Vrms and operation within a temperature range of 0°C to +130°C at 50/60 Hz frequencies. Physical dimensions are 82.55mm in length, 44.45mm in width, and 50.80mm in height, with a weight of approximately 453.59g.

Feature Summary

• Laminated core construction for efficient low-voltage power transformation
• Single primary and single secondary winding configuration with center tap
• Chassis mount installation style with wire lead terminations
• High thermal tolerance supporting operation up to +130°C

Applications

• Industrial control panel power supplies
• Low voltage equipment requiring 5V DC conversion
• Chassis-mounted electronic assemblies
• General purpose AC to DC power supply circuits

Procurement Notes

Verify the specific secondary voltage and current requirements against the 166MS datasheet before ordering. Confirm that the chassis mounting footprint and wire lead lengths meet the design constraints. Check RoHS compliance status and shipping restrictions relevant to the destination country. Ensure the 15VA rating provides sufficient headroom for the intended load application.

Selection Notes

Select the 166MS when a compact, chassis-mountable transformer is needed for 115V input systems requiring a 5V output. Consider the physical dimensions and weight relative to available space. Evaluate the thermal performance characteristics if the operating environment approaches the upper temperature limit. Compare against other series members if different voltage or power ratings are required.

Part Context

The 166MS belongs to the Hammond 166 series of industrial control transformers. This series is characterized by robust die-cast aluminum cases and high-temperature insulation materials. These components are engineered for reliability in demanding industrial environments, offering consistent performance across varying load conditions while maintaining safety standards for electrical isolation.

Replacement Considerations

Consult official Hammond Manufacturing documentation for verified substitute part numbers. Cross-reference technical specifications such as VA rating, voltage, and physical dimensions to ensure compatibility. Generic equivalents may not match the specific mounting or thermal requirements of the original component.
