SKU: 001252 Category: Tags: , , , , , , , ,


A **40W DC to AC 12V to 220V Step-up Transformer** is a device used to convert low-voltage DC (Direct Current) power to high-voltage AC (Alternating Current) power. Here’s what this type of step-up transformer entails:

**1. Power Rating:** The “40W” indicates the power rating of the transformer. It can handle a maximum power output of 40 watts. This means it can convert DC power up to 12V into AC power up to 220V while providing a maximum output of 40 watts.

**2. Input Voltage:** The transformer takes a low-voltage DC input, typically 12V in this case. The input voltage can vary, but it’s essential to match the transformer’s input voltage with your power source.

**3. Output Voltage:** The transformer increases the input voltage to 220V AC. This elevated voltage is suitable for powering devices that require higher voltage levels than the input.

**4. Step-up Transformation:** This device is a step-up transformer, meaning it raises the input voltage to a higher output voltage. Step-up transformers are used in situations where you need to increase the voltage for specific applications or devices.

**5. DC to AC Conversion:** The transformer converts DC power to AC power. This can be useful for running AC appliances or devices from a DC power source, such as a battery or a solar panel system.

**6. Applications:** Step-up transformers are commonly used in various scenarios, including automotive applications (e.g., for powering AC devices in vehicles), inverter circuits (for providing household-like AC power from DC sources), and in electronics projects that require specific voltage levels.

**7. Power Limitation:** The 40W power limitation means that the transformer can handle devices or loads that consume up to 40 watts of power. It’s important not to exceed this power rating to prevent overheating or damage to the transformer.

**8. Output Socket or Connection:** The transformer may have an output socket or terminals for connecting to the load, such as a power plug for standard household devices or a connection for specific applications.

**9. Safety Considerations:** When working with high-voltage AC power, safety precautions are crucial. Ensure proper grounding, insulation, and safety measures to avoid electric shock and hazards.

In summary, a **40W DC to AC 12V to 220V Step-up Transformer** is a device that takes a 12V DC input and converts it into 220V AC output power. It’s used for various applications, including powering AC devices from a DC source, and it’s important to stay within the specified power limits and follow safety guidelines when using such transformers.
