Boss BRA-100 Power Supply 12V AC (USA Plug, Made in Japan)

The Boss BRA-100 is an original 12V AC power supply designed for specific Boss and Roland devices requiring an AC output rather than the more common DC adapters. Delivering 12 volt alternating current, this adapter is intended for equipment that relies on AC power input for proper operation and circuit functionality.

This version features a USA / Japan style plug and is designed for 100V AC mains voltage, as used in Japan and certain other regions. Because the adapter operates on 100V input, a suitable step-down transformer is required when using it in regions with higher mains voltage such as 230V.

As an original Made in Japan Boss power supply, the BRA-100 is suitable for users seeking a correct replacement adapter for compatible vintage or region-specific equipment requiring 12V AC power.
