TCT40-09E07K

Power Transformers Overview

The TCT40-09E07K is a laminated core power transformer manufactured by Triad Magnetics, rated at 40VA. It features a single primary winding with multi-tap inputs for 208V and 240V operation, and a single secondary output providing 24V at 1.67A maximum current. The unit utilizes wire leads for termination and is designed for chassis mounting. Key electrical specifications include a 1500Vrms isolation voltage and an operating frequency of 50Hz/60Hz. The physical dimensions are 92.46mm in length, 56.67mm in width, and 57.40mm in maximum height.

Power Transformers Feature Summary

• Class 2 control transformer design compliant with UL1585 standards
• Multi-tapped primary winding supports dual input voltages
• Laminated core construction for efficient power transfer
• Wire lead termination facilitates direct circuit connection

Power Transformers Applications

• Industrial control panels requiring Class 2 isolation
• Chassis-mounted equipment power supplies
• Low-voltage control circuit powering
• General industrial machinery internal wiring

Power Transformers Procurement Notes

Verify the specific suffix 'K' to confirm wire lead configuration, as other variants may use quick-connect terminals. Ensure the required primary voltage (208V or 240V) matches the available taps on this specific model. Confirm that the chassis mounting style aligns with the mechanical layout of the target enclosure before finalizing the order.

Power Transformers Selection Notes

Select this component when a 40VA capacity is sufficient for the load requirements. The 24V secondary output must match the control circuit voltage needs. Consider the wire lead termination type if soldering or crimping is preferred over screw terminals. Verify that the physical footprint fits within the designated chassis space, accounting for the 57.40mm height constraint.

Power Transformers Part Context

This part belongs to the Triad Magnetics TCT series of industrial control transformers. These units are designed for robust performance in demanding environments. The TCT40-09E07K specifically addresses applications needing reliable step-down conversion from standard line voltages to safer low-voltage levels for control logic and signaling circuits.

Power Transformers Replacement Considerations

TCT40-09E07AB is a functional substitute but uses quick-connect terminals instead of wire leads. Verify mechanical mounting compatibility and terminal interface differences before swapping. Ensure the replacement maintains the same 40VA rating and 24V output specification.
