Low Frequency Step Down Transformer EI41 Power Transformer Pins 4+4 110V-12V

1.Product Description

A Step Down EI41 Power Transformer is a crucial electrical device designed to reduce the voltage level in power distribution systems. The "Step Down" indicates its primary function of decreasing the input voltage to a lower, more suitable output voltage for specific applications. The "EI41" refers to its physical structure and size. The E - shaped and I - shaped laminations, when assembled, form a magnetic core. The number "41" likely represents a specific dimension, such as the core size or a parameter related to its magnetic properties.

This type of transformer is constructed with multiple windings. The primary winding is connected to the high - voltage input source, while the secondary winding provides the stepped - down output voltage. The magnetic core plays a vital role in efficiently transferring electrical energy between the windings through magnetic induction. Laminating the core helps to minimize eddy - current losses, improving the transformer's overall efficiency.

In applications, Step Down EI41 Power Transformers are commonly used in various electrical appliances and industrial equipment. For instance, in household electronics like televisions or chargers, they convert the high - voltage mains supply to a lower voltage that can be safely used by the internal components. In industrial settings, they might be employed to step down high - voltage power for machinery or to provide the appropriate voltage for control circuits. Their reliability and relatively simple design make them a popular choice for power conversion tasks where a stable reduction in voltage is required.

2.Features

1. Efficient voltage reduction
--Significant voltage reduction capability: "Step Down" clarifies its core function, and the EI41 type step-down power transformer can stably reduce high input voltage to the required low output voltage to adapt to the working requirements of different devices. For example, when converting the mains power (commonly 220V or 110V) into the low voltage required for the internal circuit of electronic devices (such as 12V, 5V, etc.), it can accurately reduce the voltage to ensure the safe and stable operation of the equipment.

--Accurate voltage conversion: Through carefully designed winding turns ratio, this transformer can achieve precise voltage conversion. The primary winding has more turns and is connected to a high voltage input, while the secondary winding has fewer turns and outputs a low voltage. The precise setting of the turns ratio ensures the accuracy of the output voltage and meets various application scenarios that require high voltage accuracy, such as electronic instruments, communication equipment, etc.

2. Unique EI41 structure
--High magnetic permeability: The EI41 type magnetic core is composed of E-type and I-type silicon steel sheets stacked together, which can effectively concentrate and guide the magnetic field, and has a high magnetic permeability. High magnetic permeability enables transformers to more efficiently convert electrical energy into magnetic energy and then back into electrical energy during electromagnetic conversion, reducing energy loss and improving transformer efficiency.

--Compact structure design: The EI41 specification design ensures good magnetic performance while achieving structural compactness. Compared to other transformer structures, it occupies less space and is easy to layout and install in various electrical equipment. Whether it is small household electronic devices or industrial control cabinets with limited space, it can be easily adapted.

3. Low loss and heat dissipation
--Low eddy current and hysteresis loss: The laminated structure and material properties of silicon steel sheets effectively reduce eddy current loss. The insulation treatment between each layer of silicon steel sheets prevents eddy currents from forming large-scale circulation in the iron core, reducing the heat and energy loss caused by eddy currents. At the same time, silicon steel material itself has low hysteresis loss, and during the repeated magnetic field alternation process, the energy consumed by magnetic domain flipping is reduced, further improving the efficiency of the transformer.

--Good heat dissipation performance: The EI type structure enables the heat generated by the transformer to be evenly dissipated during operation. The larger heat dissipation surface area and natural air circulation channels between the iron core and winding help to transfer heat to the surrounding environment in a timely manner, ensuring that the performance of the transformer will not decrease due to overheating during long-term operation and extending the service life of the equipment.

4. Widely applicable adaptability
--Strong universality: Due to its standard EI41 specification and flexible voltage reduction capability, this transformer is widely used in various electronic devices and power systems. It can be found in common household appliances such as televisions and computer power adapters, as well as motor control systems and automation equipment in industrial production, to meet the needs of different industries and devices for step-down power supplies.

--High reliability: After long-term technological development and practical verification, the design and manufacturing process of Step Down EI41 Power Transformer is mature, with a simple and stable structure. This reliability enables it to continuously and stably provide step-down power in various complex working environments, reducing equipment downtime caused by transformer failures and improving the overall operational stability of the system.
