AC-AC wall adapters, also called AC transformers, are external power supplies designed to convert the voltage of alternating current (AC) from a wall outlet to a different (lower) AC voltage. Unlike the more common AC/DC adapters, AC/AC adapters maintain the alternating current nature of the electricity. The primary function of an AC/AC power adapter is to step down or step up the AC voltage to match the requirements of specific electronic devices. These adapters come in different voltage and current ratings to meet the particular requirements of appliances that rely on AC input. Additionally, AC power adapters typically feature a plug-in design for convenience and compatibility with household or industrial power outlets.
Why Buy AC-AC Wall Adapters?
Certain electronics are designed to work with AC and require voltage conversion. An AC/AC adapter is a specific type of power adapter designed to achieve voltage alteration. This is especially true when using electronics designed for international voltage standards. Additionally, investing in the correct AC/AC adapter ensures the safe and efficient performance of electronic devices, preventing damage that could occur from voltage mismatches.
AC/AC Power Supplies vs. AC/DC Power Adapters:
When reviewing a range of AC/AC wall adapters, several key features become apparent. These devices vary in their voltage transformation capabilities, power ratings, plug and socket types, and build quality and safety features.
It is very important to contrast those points against AC/DC adapters. The difference is the output type. AC/DC adapters change AC from the wall outlet into a stable flow of DC, the type of current needed to power most consumer electronics like laptops, phones, and televisions. These adapters contain rectifier circuits, which are not present in AC/AC adapters.
Typical Uses of AC-AC Wall Adapters:
AC/AC wall adapters are typically employed in situations where devices require a specific AC voltage that differs from the standard household supply. Some typical applications include:
- Audio Equipment
- Electric Motors & Fans
- Lighting Systems
- Industrial Control Systems
- Security Systems
- Medical Equipment
- Musical Instruments
- International Electronics.
