266L16

Power Transformers Overview

The Hammond Manufacturing 266L16 is a laminated core power transformer designed for chassis mounting. It features dual primary windings rated for 115 VAC and 230 VAC operation at 50 Hz or 60 Hz. The secondary configuration provides dual outputs of 8V @ 4.4A in parallel or 16V @ 2.2A in series, delivering a total power rating of 35.2 VA. Physical dimensions are 93.72 mm in length, 55.88 mm in width, and 59.69 mm in height. It utilizes wire leads for termination and operates within a temperature range of 0°C to +130°C.

Power Transformers Feature Summary

• Dual primary winding capability allows flexible connection to either 115 VAC or 230 VAC input sources.
• Configurable secondary output supports parallel low-voltage high-current or series higher-voltage applications.
• Robust laminated core construction ensures stable performance for industrial control environments.

Power Transformers Applications

• Industrial control panel power supplies
• Chassis-mounted equipment requiring isolated AC power
• Low voltage filament or heater circuits

Power Transformers Procurement Notes

Verify the specific secondary configuration required (parallel vs. series) against the application circuit design before procurement. Confirm that the chassis mounting holes align with the specified physical dimensions. Ensure the input voltage matches the dual primary winding ratings. Check RoHS compliance status if environmental regulations apply to the final assembly.

Power Transformers Selection Notes

Select this model when a 35.2 VA capacity is needed with flexible secondary voltage options. The dual primary feature simplifies inventory management for global deployments. Consider the chassis mount style and wire lead termination method during mechanical integration. Evaluate thermal requirements as the maximum operating temperature reaches +130°C.

Power Transformers Part Context

This component belongs to the Hammond 266 Series of industrial control transformers. The series offers various power ratings and voltage configurations tailored for general-purpose industrial applications. The 266L16 specifically addresses needs for moderate power isolation with configurable secondary outputs.

Power Transformers Replacement Considerations

Consult official Hammond Manufacturing documentation for direct cross-references. Verify pinout compatibility and physical footprint if substituting with other manufacturers' equivalents. Ensure electrical ratings meet or exceed the original specifications.
