Overview
The Talema Group LLC 0500MD-1-004 is a medical-grade toroidal power transformer with a 500VA maximum power rating. It features dual primary windings supporting 100V, 120V, 200V, and 240V inputs. The secondary configuration offers parallel 120V or series 240V outputs, delivering up to 830mA in parallel mode and 420mA in series mode. Designed for chassis mounting, it provides 5000Vrms isolation voltage and measures 99.00mm in diameter by 41.00mm in width.
Feature Summary
- Medical grade construction compliant with safety standards
- Toroidal core design for efficient magnetic coupling
- Dual primary winding flexibility for global voltage compatibility
- High isolation voltage capability for patient-safe applications
Applications
- Medical diagnostic equipment requiring isolated power
- Patient monitoring systems needing high reliability
- Industrial control panels utilizing chassis mounting
- Power supply units for sensitive electronic instrumentation
Procurement Notes
Verify the specific output current requirements against the parallel or series configuration before ordering. Confirm that the chassis mounting dimensions align with the enclosure design. Ensure the input voltage range matches the local power distribution standards. Check for any specific medical certification documentation required for regulatory compliance in the target market.
Selection Notes
Select this model when a 500VA capacity is necessary for medical or industrial applications. Choose the parallel secondary setting for lower voltage, higher current needs. Opt for the series configuration if higher voltage output is required at reduced current. Consider the toroidal form factor for space-constrained installations where low electromagnetic interference is critical.
Part Context
This component belongs to the MD Series, which is designated as medical grade within the Talema Group LLC product line. The series specializes in toroidal transformers designed for high reliability and safety in healthcare environments. The 0500MD-1-004 variant specifically addresses the need for robust power conversion in medium-power medical devices.
Replacement Considerations
Direct substitutes include other Talema MD series models with matching VA ratings, such as the 0300MD-1-004 for lower power or 1200MD-1-004 for higher capacity. Verify that any replacement maintains the same 5000Vrms isolation and chassis mounting specifications.
