Overview
The Talema Group LLC 0050MD-1-003 is a medium-grade toroidal power transformer with a 50VA rating. It features dual multi-tap primary windings supporting 100V, 120V, 200V, and 240V inputs in parallel or series configurations. The secondary provides 120V at 420mA and 240V at 210mA. Designed for chassis mounting, it offers 5kV isolation voltage.
Feature Summary
- Toroidal core construction for efficient magnetic coupling
- Dual multi-tap primary winding configuration for flexible input voltage compatibility
- High isolation voltage capability for safety compliance
- Chassis mount design for secure industrial installation
Applications
- Industrial control systems requiring isolated power
- Medical equipment power supplies
- Test and measurement instrumentation
- Audio processing equipment
Procurement Notes
Verify the specific datasheet version to confirm pinout and insulation class. Ensure the application environment temperature aligns with the transformer's thermal ratings. Confirm that the required primary voltage configuration matches the available tap options. Check mechanical dimensions against the chassis mounting space constraints before finalizing procurement.
Selection Notes
Select this component when a 50VA toroidal transformer is needed with flexible primary voltage options. The dual secondary outputs support both 120V and 240V requirements. Consider the chassis mount style for fixed installations. Verify that the 5kV isolation meets the safety standards of the target equipment.
Part Context
This part belongs to Talema's standard toroidal transformer line, designed for general-purpose power conversion. The 'MD' designation indicates a medium-grade build quality suitable for commercial and light industrial applications. It is distinct from high-reliability military or aerospace variants.
Replacement Considerations
Direct substitutes must match the 50VA rating, toroidal form factor, and electrical specifications. Verify that alternative transformers support the same primary tap configurations and secondary voltage/current outputs. Mechanical footprint compatibility is essential for chassis-mounted replacements.
