How to Choose the Right AC Adapter for Your LED Lights

The right ac adapter for your device is one with matching electrical ratings. The device’s input voltage and current must match the adapter’s output voltage and current. Check the device’s product label or user manual to see its rated voltage and current. Shoppers learning how to choose AC adapter should know that most power adapters have output DC voltages below 20V while their input AC voltages are over 100V.

Check Electrical Ratings to choose the correct AC Adaptors for the LED Lighing

Before trying to find a matching AC adapter for a device, check if the OEM (original equipment manufacturer) adapter is available. Device manufacturers sometimes offer replacement chargers/adapters for their products. Determining how to choose the right power adapter for a device becomes easy if this OEM accessory is available. Find the specific adapter for the device by searching for it using the model number printed on the ac dc adapter shipped with the device.

In some cases, OEM adapters are no longer available from manufacturers. Therefore, finding the right power adaptor for your electronics requires selecting a compatible third-party accessory. The first step is to determine the electrical rating of the device.

When learning how to choose an AC adapter, it is also necessary to understand power adapter specifications. Manufacturers usually print such information on the labels of these power accessories. Alternatively, check the device’s user manual for the electrical ratings of its AC adapter. The most important sections to read on a power adapter label are voltage and current. However, polarity is also an important factor.

The unit for voltage is volt (V), while current ratings end in amps or ampere (A). Power adapters have AC inputs and DC outputs. Depending on the region, AC input can be 110/120V or 220/240V. To make it easier for users to choose an AC adapter, manufacturers usually offer adapters that support both voltages. Dual voltage adapters have listed input AC voltage ranges of 110 - 220VAC or 100 - 240VAC. These are most useful for travelers researching how to choose the right power adapter that will work in other parts of the world. The DC voltage (VDC) of the power accessory is as important as its AC voltage (VAC). When reading an adapter label, the VDC will be under the DC symbol.
