Product Description
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.
Application Reference Guide
| Industry or Equipment | Typical Function | Input Range | Output Range | Power Reference | Frequency | Customization Priorities |
|---|---|---|---|---|---|---|
| Industrial automation | Control-circuit isolation and voltage conversion | 110–480 V AC | 6–240 V AC | 100 VA–3 kVA | 50 or 60 Hz | Multiple taps, low temperature rise, terminal layout |
| Machine tools and production equipment | Power for control panels and auxiliaries | 200–480 V AC | 24–220 V AC | 200 VA–5 kVA | 50 or 60 Hz | High dielectric margin, vibration resistance |
| Emergency power and UPS | Auxiliary supply control isolation | 110–480 V AC | 12–240 V AC | 100 VA–3 kVA | 50 or 60 Hz | Low no-load loss, standby thermal performance |
| Energy storage and PCS cabinets | Auxiliary power for controls and monitoring | 208–480 V AC | 24–230 V AC | 200 VA–5 kVA | 50 or 60 Hz | Wide input tolerance, temperature monitoring |
| EV charging equipment | Isolated auxiliary power for charger controls | 110–480 V AC | 12–240 V AC | 150 VA–3 kVA | 50 or 60 Hz | Surge environment, thermal cycling |
Inquiry Requirements: Define primary and secondary voltages, rated VA, frequency, load type, duty cycle, voltage-regulation limit, no-load current, efficiency or loss target, ambient temperature, allowable temperature rise, insulation class, dielectric test requirement, creepage and clearance, thermal protection, electrostatic shield, mounting dimensions, terminal arrangement, enclosure conditions, applicable standards, forecast volume, and required production tests.
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 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.
Construction Details
| Component | Customization Reference |
|---|---|
| Magnetic core | EI-shaped laminated silicon-steel platform with stack selected according to voltage, power loss and thermal requirements |
| Lamination material | Steel grade and thickness selected to balance no-load loss, magnetizing current, audible noise, temperature rise and cost |
| Primary winding | Single-voltage, dual-voltage or multi-tap design with customer-defined input tolerance and frequency |
| Secondary winding | Single, multiple, center-tapped or isolated outputs according to voltage, current, regulation and insulation requirements |
| Terminal system | Insulated terminal blocks with customizable count, position, material, color, marking and cover |
| Thermal protection | Optional thermal fuse, thermostat, thermistor or other sensor with rating, position and wiring defined by agreement |
| Electrostatic shield | Optional primary-to-secondary shield with dedicated grounding lead for capacitive-noise control |

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.

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.
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.
