70082K

Power Transformers Overview

The 70082K is a toroidal power transformer manufactured by Talema Group LLC, designed for PCB mounting applications. It features dual primary windings rated for 115V and 230V AC input, configurable for parallel or series connection to accommodate varying line voltages. The secondary output provides dual 12V windings, which can be connected in parallel to deliver 4.166A or in series to yield 24V at 2.083A. This component belongs to the 70000K series of low-profile transformers, offering a compact form factor suitable for space-constrained designs.

Power Transformers Feature Summary

• Toroidal core construction for efficient magnetic coupling
• Dual primary voltage configuration supporting 115V/230V operation
• Flexible secondary output options for parallel or series connectivity

Power Transformers Applications

• Low profile PCB mounting power supplies
• Equipment requiring isolated 12V or 24V DC conversion
• Compact electronic devices with strict height constraints

Power Transformers Procurement Notes

Verify the specific ordering suffix required for your application, as Talema may offer variations in insulation class or terminal type. Confirm that the maximum seated height of 37.50mm fits within your mechanical enclosure limits. Ensure the input voltage matches the primary winding configuration before installation. Check for any specific regulatory certifications required for your target market compliance.

Power Transformers Selection Notes

Select this model when a low-profile toroidal transformer is needed for high-efficiency power conversion. The dual primary design simplifies global voltage compatibility without changing components. Consider the physical dimensions carefully, as the 37.50mm height is a critical constraint. Evaluate whether the 50VA rating meets the total load requirements of the downstream circuitry.

Power Transformers Part Context

The 70082K is part of the 70000K series from Talema Group LLC, which specializes in custom and standard magnetic components. This series focuses on low-profile PCB mounting toroidal transformers ranging from 1.6VA to 50VA. The manufacturer has been producing these components since 1975, emphasizing custom design capabilities alongside standard off-the-shelf availability through global distributor networks.

Power Transformers Replacement Considerations

No direct public substitute part numbers are confirmed for this specific model. When seeking alternatives, prioritize toroidal transformers with identical 50VA ratings, 37.50mm max height, and dual 12V secondary configurations. Verify that any replacement supports the same dual primary voltage inputs and PCB mounting style.
