266J24B

Power Transformers Overview

The Hammond Manufacturing 266J24B is a chassis-mount industrial control transformer with a 24 VA power rating. It features dual primary windings for 115 VAC and 230 VAC input at 50/60 Hz. The secondary output provides 24 VAC center-tapped at 1 A, or dual independent windings. Constructed with a laminated core, it utilizes wire lead terminations for connection. The unit measures 82.55 mm in length, 50.8 mm in width, and 50.8 mm in height, weighing approximately 725.7 g. It operates within a temperature range of 0°C to +130°C.

Power Transformers Feature Summary

• Dual primary winding configuration supports both 115 VAC and 230 VAC input voltages.
• Secondary windings are configurable as a center-tapped circuit or used as two independent outputs.
• Chassis mounting design facilitates secure installation in industrial control enclosures.
• Wire lead termination allows for direct integration into custom wiring harnesses.

Power Transformers Applications

• Industrial control panel power distribution
• Low voltage filament supply circuits
• Rectifier transformer applications requiring isolated DC sources

Power Transformers Procurement Notes

Verify the specific secondary configuration required, as the dual secondaries can be wired for center-tap or independent use. Confirm that the chassis mounting dimensions align with the enclosure space. Ensure the input voltage matches the available primary winding setting. Check RoHS compliance status if environmental regulations apply to the deployment environment.

Power Transformers Selection Notes

Select this model when a low-voltage, high-current isolation transformer is needed for chassis-mounted installations. The dual primary capability simplifies inventory for global deployments. Consider the physical dimensions and weight for structural support requirements. Verify that the 24 VA rating meets the load demands of the connected control components without exceeding thermal limits.

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 control applications. Similar models in the series include the 266N24 and 266J26, which differ primarily in power capacity and secondary voltage specifications while maintaining comparable mounting styles.

Power Transformers Replacement Considerations

Direct substitutes within the same series include the 266J26, though it offers a different secondary voltage (26.8 VAC CT). Ensure any replacement maintains the 24 VA rating and chassis mounting footprint to fit existing enclosures without modification.
