The Hosa ACD-477 Universal Power Adapter auto-detects AC input from 100-240V, 50/60Hz allowing for global use. All you need for use outside of the United States is a US to local power plug adapter.
Many devices on the market have different voltage requirements, and the Hosa ACD-477 Universal Power Adapter allows you to switch from 3, 4.5, 6, 7.5, 9, or 12 V operation with a simple turn of the knob on the face of the adapter. Just make sure to have the ACD-477 unplugged from any device when changing DC output voltage. The ACD-477 runs at 80% efficiency with a 1200mA maximum output.
Many small electronics are made with many different sized plugs. The Hosa ACD-477 Universal Power Adapter conveniently comes with six of the most common types on the market, giving you the versatility to use the same power supply across multiple devices.
To protect your device from experiencing electric spikes which could damage them, the Hosa ACD-477 Universal Power Adapter has a built in SCP (short circuit protection). When the LED light starts to dim, you should unplug your device to prevent any damage.
Many professionals keep safeguards when they’re at a gig in case there is some type of failure. The Hosa ACD-477 Universal Power Adapter is light, small, and the AC plug folds into the design, saving storage space and making it even more compact for the gigging professionals.
For devices like pedalboards where you can utilize one power supply for multiple devices, Hosa also offers the PDC-373 Daisy Chain Extension Cord. These split a single 2.1 mm DC plug to up to 2.1 mm DC jacks, often used for guitar pedals.
