Frequently Asked Questions
Is the product shown a toroidal transformer?
No. Although the image headline refers to a toroidal transformer, the pictured product uses a rectangular EI laminated core. It should be described as an EI48 low frequency transformer.
Is the output voltage fixed at 24V?
No. The image presents a 24V configuration, but input and output voltages can be customized. Final output voltage, current and regulation must be confirmed in the approved specification.
What information is required for customization?
Please provide input voltage, frequency, output voltage, output current or VA rating, duty cycle, ambient temperature, maximum dimensions, mounting method, connector requirements, insulation requirements, protection devices and annual demand.
Can the EI48 support dual input voltages?
Yes. Dual primary windings or multiple input taps can be developed when winding space and insulation requirements permit.
