Model and Type: YZ30S20-1007B-EI30 is a specific model or part number for this transformer, and "EI30" is likely referring to its core type.
Power Rating: It is a 2VA transformer, which stands for Volt-Ampere, and is a unit of electrical power. This rating indicates that the transformer can handle a load of up to 2 VA. Transformers are often rated in VA rather than watts because they are designed for AC power, and VA accounts for both the real power (in watts) and reactive power due to the nature of AC circuits.
Input Voltage: This transformer is designed to accept an input voltage in the range of 220V to 240V. This input voltage range suggests that it can be used in regions where the standard line voltage is in this range, such as many countries in Europe.
Output Voltage: The transformer steps down the input voltage to provide an output voltage of 10V and 12V. It typically offers multiple output windings, with one providing 10V and another providing 12V.
Step-Down Transformer: This transformer is a step-down type, meaning it reduces the input voltage to a lower output voltage. Step-down transformers are commonly used to power devices that require lower voltage than the available line voltage.
Encapsulated: The term "encapsulated" suggests that the transformer's internal components are sealed within an encapsulating material, often epoxy or resin. This provides protection against environmental factors, such as moisture, dust, and physical damage. Encapsulation can also enhance safety by preventing direct contact with the internal components.
Safety Transformer: The term "safety transformer" implies that this transformer is designed with safety in mind, possibly including features like overcurrent protection, overvoltage protection, or other safety mechanisms to protect against electrical hazards.
Voltage Compatibility: This transformer is designed for use with both 220V and 240V input voltages, which are commonly found in different parts of the world. The transformer can be wired to operate with either voltage, making it versatile for use in various regions.
In summary, the YZ30S20-1007B-EI30 2VA 220V 240V to 10V 12V Step Down Encapsulated Safety Transformer is a compact and versatile electrical transformer with a focus on safety, designed to reduce high-voltage AC power to lower-voltage AC power. It can be used in regions with 220V or 240V line voltages and is encapsulated for protection and safety.
