KOZUMUWAN AC 9V Center PSE Major Manufacturer OEM DC Outer Inner Universal Compatible with Genuine Switching for Musical and Home Use Current Adapter,

------------------------------------------------------------------------------------------------------------------ 【Voltage Compatibility】 When using electrical appliances, please note that they are designed for Japanese voltage specifications (90-110V), so if you use them with a different voltage, it may cause a malfunction.

【Plug Type】 Our products use Japanese plug types (A or B type). Please use a conversion adapter if necessary.

【Important Note on Transformers and Adapters】 A transformer adjusts voltage to match your device’s requirements. A conversion adapter only changes the plug shape and does not adjust voltage. Using only a conversion adapter without a transformer may result in damage to the product.

【Liability】 We are not responsible for malfunctions or damages caused by improper use, such as operating the product without a transformer. ------------------------------------------------------------------------------------------------------------------

■ [Official Sales by a Local Japanese Subsidiary] With over 10 years of sales experience and the industry's largest variety of products, these are products from a trusted manufacturer that is used by major Japanese companies. PSE compliant, officially imported (importer marked). One-year manufacturer's warranty from the date of shipment. ■[DC Stabilized Output & Worldwide Compatibility] The input voltage is compatible with AC 100-240V 50/60Hz, allowing for safe use overseas. The DC output plug has an outer diameter of 5.5mm and an inner diameter of 2.1mm, and is center positive by default. *A center negative plug is also available for the 9V model. ■【Equipped with Circuit Protection】Highly reliable electrolytic capacitors, which determine the adapter's lifespan, are equipped with overvoltage protection, overheating protection, overcurrent protection, and short circuit protection. It can be used to power LED lights, switches, security cameras, surveillance cameras, strip lights, audio/video devices, cell phones, hubs, musical instruments, guitars, home appliances, toys, general-purpose GPS, tablets, LED strips, routers, speakers, monitors, camera adapters, TV boxes, GPS, and other products. ■ [Precautions for use] Cannot be used as a charger. Not suitable for applications requiring high reliability (precision equipment, medical equipment, etc.). *Items such as motors that have a current (peak current) that significantly exceeds the rated current when powered on (starting) may not work. Please make sure that the peak current is covered. ■"How to choose an AC adapter" 1. Voltage: As a general rule, do not use an adapter with a different voltage as this may cause a malfunction. ■ "How to choose an AC adapter" 2. Current: As a general rule, choose an adapter with the same current as the device (if the same current is not available, choose the closest larger one). For example, if the device is labeled 800mA, choose a 1A adapter, and if it is 1.5A, choose a 2A model. ■ "How to Choose an AC Adapter" 3. DC plug diameter: If you connect a 2.5mm plug to a 2.1mm plug, the power may turn on, but poor contact may occur, so please choose a 2.1mm model. *All AC adapters we sell are 5.5 x 2.1mm, but we also carry a wide variety of plug conversion adapters. ■ "How to Choose an AC Adapter" 4. Polarity: AC adapters have polarity, and some have a positive or negative center. If you connect the polarity incorrectly, it can burn or damage parts, so be careful. ■"How to Choose an AC Adapter" 5. Please check the power specifications of your device in the instruction manual or the markings on the device itself. *If an adapter with the wrong specifications is used and the device is damaged, the warranty will not apply. ■Highly reliable electrolytic capacitors, which determine the adapter's lifespan, are equipped with overvoltage protection, overheat protection, overcurrent protection, and short circuit protection. This product complies with the Electrical Safety Act PSE and is an officially imported product (importer listed). It comes with a one-year manufacturer's warranty from the date of shipment. Highly reliable electrolytic capacitors, which determine the adapter's lifespan, are equipped with overvoltage, overheating, overcurrent, and short-circuit protection. It can be used to power LED lights, wireless routers, hubs, switches, security cameras, audio/video devices, and other products. Caution: Cannot be used as a charger. Not suitable for applications requiring high reliability (precision instruments, medical equipment, etc.). Even switching AC adapters generate heat depending on the current flowing through them. Prolonged use in enclosed spaces or high temperatures (above 40°C) can cause malfunctions or significantly shorten their lifespan. Use in a well-ventilated area. Switching AC adapters may emit a slight audible noise depending on the current draw. This is due to the circuitry used to adjust the voltage and is not abnormal. Note: Motors, for example, may not operate when powered on (starting), drawing currents (peak currents) significantly higher than their rated current. Make sure that the peak current is covered. Please note. How to Choose an AC Adapter: There are many AC adapters on the market, but just because they look similar doesn't mean they're the right choice. Using an adapter with the wrong rated voltage or current can cause fire or damage to your equipment. Furthermore, if the plug shape is incorrect, it may not even work. Here, we'll explain how to choose an AC adapter. 1. Check the voltage and current of the device: Electrical devices require an adapter with the appropriate voltage and current. First, check the voltage and current of the device you want to connect to the adapter. This is often written as "○V/○A" near the input terminal. 2. Check the plug shape: In fact, AC adapter connectors and device sockets are not standardized; there are various standards, such as those with pins on the plug side and those with pins on the jack side. Since the connector shape cannot be determined from the device's model number alone, it's important to check the size and shape before purchasing to avoid any issues with the adapter not fitting after purchase. *All AC adapters sold by our company are 5.5 x 2.1 mm, but we also carry a wide variety of plug conversion adapters. 3. Check the polarity: Depending on the device, it may be necessary to send power via a positive or negative terminal. Getting this wrong could damage the device, so be sure to check. Example of selecting an AC adapter: * Power supply voltage: Standard 12V * DC jack 2.1 center positive * Operating current: Maximum 1.5A. Therefore, in this case, select the "AC adapter DC12V 2A." The AC adapter specifications state * Rated output: DC12V 2A * Plug shape: 2.1 center positive, so we can see that a 2.1mm center positive plug with a usage value of 1.5A and a maximum supply capacity of 2A can be used without any problems.
