290ZH

Power Transformers Overview

The Hammond Manufacturing 290ZH is an open-type power transformer with a 325 VA rating, designed for industrial control applications. It features a single primary winding and triple secondary windings to provide multiple voltage outputs. The unit utilizes wire lead termination for circuit integration and is constructed as an open-style component without an enclosing chassis.

Power Transformers Feature Summary

• Provides three distinct secondary voltage outputs from a single primary input
• Designed for open mounting in custom industrial control assemblies
• Utilizes wire leads for direct electrical connection

Power Transformers Applications

• Industrial control panel power distribution
• Custom machinery power supply units
• Equipment requiring multiple isolated low-voltage rails

Power Transformers Procurement Notes

Verify the specific secondary voltage configuration required for your application against the manufacturer's datasheet before ordering. Confirm that the open-frame design meets the environmental protection standards of your installation site. Ensure adequate clearance is available for heat dissipation around the exposed core and windings.

Power Transformers Selection Notes

Select this model when a high-power 325 VA capacity is needed with multiple secondary voltages. Compare dimensions and weight against available space in the control enclosure. Verify that the operating frequency matches the system requirements and that the wire lead gauge is sufficient for the load current.

Power Transformers Part Context

This component belongs to the Hammond 290 series of power transformers. It serves as a specialized variant within the open-type control transformer category, offering higher power density compared to smaller signal transformers while maintaining flexibility for custom integration into larger industrial systems.

Power Transformers Replacement Considerations

Check for exact VA rating and secondary voltage matches in the 290 series. Verify physical footprint compatibility if retrofitting existing equipment.
