266M2

Power Transformers Overview

The Hammond Manufacturing 266M2 is a chassis-mount power transformer designed for industrial control applications. It features a dual primary winding configuration supporting both 115 VAC and 230 VAC input voltages, ensuring compatibility with various global power standards. The unit provides a low-voltage filament output of 2.5 VAC center-tapped, capable of delivering up to 3 A or 1.25 A at 6 A depending on the secondary connection. With a power rating of 7.5 VA, it operates within a frequency range of 50 Hz/60 Hz and withstands ambient temperatures from 0°C to +130°C. The component utilizes wire leads for termination and measures approximately 82.55 mm in length, 52.32 mm in width, and 50.8 mm in height.

Power Transformers Feature Summary

• Dual primary winding design enables flexible operation across 115 VAC and 230 VAC input systems.
• Center-tapped secondary output supports multiple current configurations for filament or low-voltage control circuits.
• Chassis mounting style facilitates secure installation within industrial enclosures and control panels.

Power Transformers Applications

• Industrial control panel power supply
• Filament heating for vacuum tubes or lamps
• Low-voltage signal processing circuits

Power Transformers Procurement Notes

Verify that the specific order matches the manufacturer part number 266M2 exactly, as suffixes may indicate different packaging or voltage variants. Confirm compliance with RoHS directives if required by your project specifications. Ensure the receiving facility can handle the physical dimensions and weight specified in the datasheet. Cross-reference the lead time with current distributor availability, as manufacturing cycles may vary based on production schedules and regional demand fluctuations.

Power Transformers Selection Notes

Select this model when a compact, low-power transformer is needed for chassis-mounted installations requiring dual primary flexibility. The 7.5 VA rating suits light industrial loads where space is constrained but robust thermal performance up to 130°C is necessary. Consider the wire lead termination type against available PCB or terminal block interfaces. Evaluate the physical footprint against enclosure constraints before finalizing the design integration.

Power Transformers Part Context

This component belongs to the Hammond 266 Series, a line of industrial control transformers known for their durability and standardized form factors. The series offers a range of power ratings and voltage configurations tailored for diverse automation needs. As a chassis-mount device, it integrates directly into metal enclosures, providing reliable isolation and voltage transformation for sensitive control electronics in harsh environments.

Power Transformers Replacement Considerations

Direct substitutes are not explicitly listed in public documentation. Verify compatibility by matching VA rating, primary/secondary voltages, and physical dimensions. Alternative models from the same series, such as 266M20 or 266L6, offer higher power outputs but differ significantly in size and electrical characteristics.
