Overview
The Talema Group LLC 1000MD-1-003 is a medical-grade toroidal power transformer with a 1000VA rating. It features dual multi-tap primary windings supporting 100V, 120V, 200V, and 240V inputs. The single multi-tap secondary provides parallel 120V at 8.33A or series 240V at 4.17A. Designed for chassis mounting with wire leads, it measures 99.00mm in diameter by 41.00mm wide and weighs 10 kg. The unit offers 5000Vrms isolation voltage and complies with RoHS3 standards.
Feature Summary
- Medical grade construction compliant with safety standards
- Toroidal core design for efficient magnetic coupling
- Dual multi-tap primary winding for versatile input voltage compatibility
- Single multi-tap secondary winding allowing parallel or series output configuration
Applications
- Medical diagnostic equipment requiring isolated power
- Industrial control systems needing high reliability
- Audio processing units demanding low noise performance
Procurement Notes
Verify the specific datasheet version to confirm compliance with current medical safety regulations. Ensure the receiving facility can handle the 10 kg weight during installation. Confirm that the wire lead termination style matches the system's connection requirements before finalizing the order.
Selection Notes
Select this model when a 1000VA capacity is required for chassis-mounted applications. Choose the parallel secondary configuration for 120V outputs or series for 240V. Verify that the physical dimensions fit the available enclosure space and that the primary voltage taps align with the local power grid specifications.
Part Context
This component belongs to the MD Series, which is designated for medical-grade applications. The series utilizes toroidal transformers designed to meet stringent isolation and safety requirements typical in healthcare environments. The 1000VA rating places it in the higher power segment of the family, suitable for substantial load demands.
Replacement Considerations
Direct substitutes within the same series include the 0350MD-1-003 (350VA) and 1200MD-1-003 (1200VA). These alternatives share similar form factors and medical-grade characteristics but differ in power capacity. Ensure the replacement matches the required VA rating and electrical specifications.
