faqs

What is the Custom EI30 Series Low Frequency Transformer used for?

A: The EI30 Series transformer is a compact PCB-mount power transformer designed to step down 230V AC input to 9V AC output at 1.5VA rating. It is commonly used in industrial control circuits, consumer electronics, power supplies, test equipment, and telecommunications devices requiring safe electrical isolation and reliable low-voltage power conversion.

What does "Low Frequency" mean for this transformer?

A: "Low Frequency" indicates the transformer is designed for operation at 50Hz or 60Hz mains power frequencies. It features a laminated silicon steel core optimized for efficient power conversion at these standard power grid frequencies, as opposed to high-frequency transformers which use ferrite cores for kHz/MHz operation.

What is the power rating and output capability?

A: The transformer has a power rating of 1.5VA (volt-amperes), with a secondary output of 9V AC at approximately 166mA full load current. The no-load secondary voltage is typically higher (approximately 12.5V) to compensate for regulation under load.

What does "EI30" mean?

A: "EI30" refers to the laminated core shape and size designation. "EI" indicates an E-shaped core with a matching I-shaped core, and "30" refers to the core size (approximately 30mm dimensions). This core configuration is optimized for efficient magnetic flux transfer in low-frequency (50/60Hz) power applications.

Can the transformer be customized for different voltages?

A: Yes. The EI30 Series platform is available with various input/output voltage combinations including 6V, 9V, 12V, 15V, 18V, and 24V, with options for single primary/single secondary or single primary/dual secondary configurations. OEM and ODM customization is available to meet specific application requirements.
