Construction Details
Component Customization Reference
Core platform EI76 silicon-steel laminated core with stack thickness selected according to voltage, frequency, VA, losses and temperature rise
Lamination material Silicon-steel grade and thickness selected for magnetic loss, no-load current, noise and sourcing requirements
Primary winding Single, dual, tapped or multiple-voltage primary
Secondary winding Single, dual, multiple, center-tapped or separately isolated outputs
Winding conductor Enameled copper wire selected according to current density, voltage drop, regulation and temperature rise
Terminations Flying leads, solder lugs, quick-connect terminals, terminal blocks or customized connectors
Thermal protection Optional thermal fuse, thermostat or temperature sensor
Mounting Mounting feet with customizable hole spacing, slot dimensions and orientation
Key Characteristics

Customization Parameters
Major customizable parameters include: primary voltage, secondary voltage, rated VA, frequency, voltage taps, regulation, no-load current, no-load loss, copper loss, efficiency, temperature rise, insulation class, dielectric strength, thermal protection, electrostatic shielding, lamination stack, conductor size, terminals, lead wires, mounting brackets, impregnation, encapsulation, labeling, and production tests.
Performance Note: EI76 identifies the approximate lamination platform and does not define universal voltage, current, VA rating, insulation class, or temperature rise. Final performance depends on lamination stack, silicon-steel grade, operating voltage, frequency, core flux density, winding space, conductor size, regulation requirements, insulation system, ambient temperature, mounting, cooling, and duty cycle.
