FAQ
1 What is the 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 with a rated power of 1.5VA. It is commonly used in industrial control circuits, consumer electronics, power supplies, test equipment, and telecommunications equipment requiring safe electrical isolation and reliable low-voltage power conversion.
2 What does "low-frequency" mean for this transformer?
A: "Low-frequency" indicates that the transformer is designed to operate at 50Hz or 60Hz mains power frequencies. It utilizes a laminated silicon steel core optimized for efficient power conversion at these standard grid frequencies, unlike high-frequency transformers that use ferrite cores for kHz/MHz operation.
3 What are the rated power and output capabilities?
A: This transformer is rated at 1.5VA (volt-ampere), with a secondary output of 9V AC and a full-load current of approximately 166mA. At no load, the secondary voltage is typically higher (about 12.5V) to compensate for voltage regulation under load.
4 What does "EI30" mean?
A: "EI30" refers to the shape and size designation of the laminated core. "EI" indicates an E-shaped core paired with a corresponding I-shaped core, and "30" denotes the core size (approximately 30mm dimension). This core configuration is optimized for efficient magnetic flux transfer in low-frequency (50/60Hz) power applications.
5 Can the transformer be customized for different voltages?
A: Yes. The EI30 series platform supports a wide range of 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.
