Overview
The Talema Group LLC 0350MD-1-003 is a medium-grade toroidal power transformer with a 350VA rating. It features chassis mounting and utilizes a toroidal core design. The primary winding supports multiple voltages including 100V, 120V, 200V, and 240V in parallel configuration, or 120V and 240V in series. The secondary output provides 120V at 2.92A, available in parallel or series configurations.
Feature Summary
- Toroidal core construction for efficient magnetic coupling
- Medium-grade insulation system suitable for general power applications
- Chassis mount installation method for secure integration
Applications
- Industrial control systems requiring isolated power
- Medical equipment power supplies
- Audio amplifier power stages
Procurement Notes
Verify the specific voltage configuration required for your application, as the primary and secondary windings support multiple connection options. Confirm that the chassis mounting dimensions align with your enclosure design. Ensure the thermal environment supports the heat dissipation characteristics of a 350VA toroidal transformer. Check for any specific regulatory compliance requirements relevant to your region before finalizing the order.
Selection Notes
Select this component when a 350VA isolation transformer is needed with flexible input voltage options. The toroidal shape offers lower electromagnetic interference compared to laminated cores. Consider the physical size constraints of the chassis mount design. This model is appropriate for applications where moderate efficiency and standard insulation grades are sufficient.
Part Context
This part belongs to the Talema MD series of toroidal transformers. The series typically includes various VA ratings from 50VA to higher capacities. These components are designed for general-purpose power transformation in electronic equipment. The manufacturer emphasizes custom design capabilities alongside standard catalog items.
Replacement Considerations
Direct substitutes must match the 350VA rating, toroidal form factor, and chassis mount style. Verify equivalent electrical specifications for primary and secondary voltages. Ensure the replacement unit meets similar thermal and insulation standards. Cross-reference pinouts and mounting hole patterns if physical compatibility is critical.
