Procurement Notes
Verify the specific part number against official Talema Group LLC documentation to confirm medical grade compliance and thermal protection specifications. Ensure that the required input and output voltage configurations match the application needs. Check for RoHS3 compliance status and confirm packaging quantities through authorized distributors. Validate that the chassis mounting dimensions fit the intended enclosure design before procurement.
Selection Notes
Select this transformer when high isolation voltage and thermal protection are critical requirements. The 650VA rating supports substantial load currents compared to lower capacity models. Consider the toroidal form factor for space-constrained designs requiring reduced electromagnetic interference. Verify that the dual primary winding options align with available supply voltages in the target market.
Part Context
This component belongs to the MD Series from Talema Group LLC, which specializes in medical-grade magnetic components. The series is designed for applications requiring strict adherence to international safety standards. Talema Group LLC manufactures these transformers in Charlotte, North Carolina, offering both standard and custom magnetic solutions since 1975.
Replacement Considerations
Cross-reference with other Talema MD Series models such as 0300MD or 0760MD if power ratings differ. Verify pinout compatibility and physical dimensions before substituting. Consult official datasheets for equivalent thermal protection characteristics.
