Industrial Controls 200VA Transformer EI96 480V to 24V 60Hz Isolation

Reliable Compact EI96 Low Frequency Transformer

The EI96 is a customizable laminated-core low-frequency transformer platform rather than a single fixed electrical part. The ranges below are common inquiry references for preliminary selection and engineering discussion. They are not guaranteed EI96 ratings. Final voltage, VA capacity, current, regulation, insulation, temperature rise, dimensions, terminals, protection, and compliance requirements must be confirmed in the approved drawing and specification.

Product Overview

The EI96 is an open-frame low-frequency power and control transformer platform designed for 50 Hz and 60 Hz voltage conversion, galvanic isolation, and auxiliary power distribution. It is suitable for industrial controls, machine tools, automation equipment, energy systems, professional appliances, medical equipment, and test instruments when the final design has been validated for the application.

EI96 laminated-core transformer assembly with exposed winding, metal clamping brackets, and insulated terminal blocks

EI96 identifies the approximate lamination platform and does not establish a universal input voltage, output voltage, current, VA rating, insulation class, temperature rating, efficiency, or certification. Final performance depends on the lamination stack, steel grade, magnetic flux density, conductor size, winding arrangement, insulation system, cooling, ambient temperature, duty cycle, load power factor, mounting, and enclosure.

Frequently Asked Questions

Does EI96 define a fixed power rating?
No. EI96 identifies an approximate lamination platform. Power capability depends on stack size, frequency, flux density, winding design, insulation, regulation, temperature rise, cooling, ambient temperature, and duty cycle.

What information is required for quotation?
Please provide input and output voltages, rated VA, frequency, load current, load type, duty cycle, taps, output configuration, regulation target, ambient temperature, allowable temperature rise, insulation requirement, dimensions, terminals, annual volume, and test requirements.

Can the input and output voltage be customized?
Yes. Single-voltage, dual-voltage, multi-tap, center-tapped, and multiple-secondary arrangements can be developed within magnetic, thermal, insulation, and winding-space constraints.

Can EI96 operate at both 50 Hz and 60 Hz?
A dual-frequency version can be developed and must be validated for both frequencies. Design at 50 Hz is generally more demanding than 60 Hz at the same voltage.

Can the transformer operate from DC input?
No. A conventional EI laminated transformer requires AC input. Direct DC can saturate the core and cause excessive current, overheating, or damage.

Important Note: The EI96 platform does not by itself define fixed voltage, current, power, regulation, insulation, thermal, mechanical, or certification ratings. Final performance is confirmed only through the approved drawing, wiring diagram, specification, material system, test plan, and customer sample-validation process.
