Product Description
Compact Low Loss EI76 Silicon Steel Transformer
Stable, durable control panel transformer designed for industrial applications
Product Overview
The EI76 is a low-frequency silicon-steel control transformer platform designed for AC voltage conversion and galvanic isolation in industrial control equipment, automation panels, machinery, building controls, emergency-power equipment, and other electrical systems.
Important: The values below are common international buyer inquiry references and starting points for engineering discussion. They are not fixed or guaranteed ratings. Final requirements are confirmed through approved specification, drawing, material system, and customer sample-validation process.

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.
