1800MD-1-003

Overview

The Talema Group LLC 1800MD-1-003 is a 1800VA toroidal power transformer designed for chassis mounting. It features dual primary windings supporting 100V, 120V, 200V, and 240V inputs. The secondary output provides parallel 120V at 15A maximum current or series 240V at 7.5A maximum current. This component utilizes a segmented core cap construction method to improve medical isolation performance.

Feature Summary

• Toroidal core construction with segmented cap design
• Dual primary winding configuration for multiple input voltages
• Medical grade isolation capabilities
• Chassis mount form factor

Applications

• Medical equipment power supplies
• Industrial control systems requiring isolation
• High-power audio amplifiers
• Test and measurement instrumentation

Procurement Notes

Verify the specific voltage configuration required (parallel vs. series secondary) against the application circuit before ordering. Confirm that the chassis mounting dimensions align with the enclosure design. Ensure compliance with local safety standards for medical or industrial equipment where this transformer will be installed.

Selection Notes

Select this model when high power handling (1800VA) and low electromagnetic interference are required. The toroidal shape offers superior efficiency compared to laminated cores. Consider the physical size constraints of the chassis mount installation. Verify input voltage compatibility with the available primary taps.
