Stable Power Supply for Keyboard Playing, from Studio to Stage
When playing digital piano or synthesizer, an unsuitable power supply can cause cutouts, interference, or instability at the worst moments. The Roland PSB-230eu adapter provides a 9 V DC output with a comfortable current capacity (2000 mA), to properly power many Roland keyboards and modules, even during long practice sessions. Thanks to its center negative polarity and its 2.1/5 mm barrel connector, it offers a simple and safe solution to replace a lost, worn-out, or spare power supply unit. A smart choice for keyboardists who want a clean, stable, and ready-to-play setup, whether at home, in class, in a home studio, or at a concert.Technical specifications

Customer reviews
What customers say
Summarized and selected by AI from recent customer reviews
Power adapter that converts current to proper voltage and intensity for amplifiers. Customers said it works perfectly with Boss and Roland amps, maintaining stable 9V output with no noise. "The voltage stays at exactly 9 volts and no background noise on the amp." Some noted the cable is flat and rigid, with limited output length.

It transforms the mains current to the right voltage and current to power my boss katan mini 7-w amp. Nickel!
Flat cable, a bit rigid; in a slightly cramped office configuration I would have liked to have more length of cable\ "coming out\â from the transformer, than cable entering the transformer. But hey, I'm nitpicking.Automatically translated

Received the PSB-1U instead of the PSB-230EU.
Probably lighter (switching power supply instead of a transformer?). Perfect for Mobile CcbeAutomatically translated
