Frequently Asked Questions
What information is required to customize an EI76 transformer?
Please provide input voltage, frequency, output voltage, output current or VA rating, duty cycle, ambient temperature, maximum dimensions, mounting method, terminal arrangement, insulation requirements, protection requirements, certification needs and annual demand.
What power rating can an EI76 transformer provide?
Approximately 30VA to 150VA is typical. Actual capacity depends on core stack thickness, frequency, voltage regulation, temperature rise, winding construction, enclosure ventilation and operating duty.
Can the transformer support several input voltages?
Yes. Dual primary windings or multiple voltage taps can be designed for different supply voltages. Connection method must be defined in the approved wiring diagram.
Can multiple output voltages be provided?
Yes. Single, dual or multiple secondary windings can be designed when winding space, power capacity, insulation and temperature rise permit.
