■【Precautions for Use】 This device cannot be used as a charger. It is not suitable for applications requiring high reliability (such as precision equipment and medical devices). *Devices that have a current (peak current) that significantly exceeds the rated current when powered on (start-up), such as motors, may not work. Please check if 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 malfunctions. ■ How to Choose an AC Adapter 2. Current: As a general rule, choose an adapter with the same current as the device (if there is no adapter with the same current, choose the largest one that is closest to the device). For example, if the device is marked as 800mA, choose a 1A adapter; if it is 1.5A, choose a 2A model. ■ How to Choose an AC Adapter 3. DC Plug Diameter: Connecting a 2.5mm diameter plug to a 2.1mm diameter plug may power the device on, but poor contact may occur, so please choose a 2.1mm model for 2.1mm plugs. *All AC adapters sold by our company are 5.5 x 2.1mm, but we also handle many plug conversion adapters. ■ How to Choose an AC Adapter 4. Polarity: AC adapters have polarity, with some having a positive center and others a negative center. If you connect them with the wrong polarity, components may burn out and be damaged, so please be very careful. ■ "How to Choose an AC Adapter" 5. Check the power specifications of your device in the instruction manual or by looking at the markings on the device itself.
Please note: *If the equipment is damaged due to the use of an adapter with incorrect specifications, it will not be covered under warranty. ■High-reliability electrolytic capacitors, which affect the lifespan of the adapter, are used. Equipped with overvoltage protection, overheating protection, overcurrent protection, and short circuit protection.
This product complies with the Electrical Appliance and Material Safety Law (PSE) and is a genuine imported product (with importer information displayed). A one-year manufacturer's warranty is included from the date of shipment.
High-reliability electrolytic capacitors, which significantly impact the adapter's lifespan, are used. Features include overvoltage protection, overheating protection, overcurrent protection, and short-circuit protection.
This can be used as a power source for LED lights, wireless routers, hubs, switches, security cameras, audio equipment, video equipment, and other products. Precautions for use:
This product cannot be used as a charger. It is not suitable for applications requiring high reliability (such as precision equipment or medical devices). Even switching-type AC adapters generate heat depending on the current they supply. Prolonged use in enclosed spaces or in high temperatures (above 40°C) can cause malfunctions or significantly shorten the lifespan. Please use it in a well-ventilated area. In the case of switching-type AC adapters, a slight audible sound may be emitted from the unit depending on the current consumed, but this is due to the voltage adjustment circuit and is not a malfunction.
*Devices that draw a current significantly exceeding the rated current (peak current) when powered on (start-up), such as motors, may not operate. Please check if the device can handle the peak current.
How to choose an AC adapter:
While many AC adapters are available on the market, not all of them will do, even if they look similar. Using an adapter with the wrong voltage or current rating can cause fires or damage to equipment. Furthermore, if the plug shape is different, it won't work at all. This article will explain how to choose the right 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 indicated near the input terminal as "○V/○A".
2. Check the shape of the plug:
Actually, AC adapter connectors and device input ports are not standardized, and there are various standards such as those with pins on the plug side and those with pins on the jack side. The connector shape cannot be determined from the device model number alone, so be sure to check the size and shape beforehand to avoid the situation of "it doesn't fit" 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 supply power with a positive or negative terminal. Getting this wrong can lead to damage to the device, so be sure to check carefully.
Examples of AC adapter selection:
● Power supply voltage: Standard 12V
●DC jack 2.1 center positive
●The operating current is listed as a maximum of 1.5A.
Therefore, in this case, select the "AC adapter DC12V 2A".
The specifications section for the AC adapter states:
●Rated output: DC12V 2A
● Plug shape: It is listed as 2.1 center positive, so the usable current is 1.5A.
With a maximum supply capacity of 2A and a 2.1mm plug size with center positive polarity, it can be used without any problems.
