uPower 125


5 in stock



Power your Eurorack modules from a USB port! The Arcus Audio uPower 125 is a small power supply designed originally for testing of new modules. It’s small, light weight, and offers up to 125 mA of current for both the +12V and -12V rails. The 5V current limit depends on the USB port used so 500mA and up is possible, 375mA minimum if using USB 2.0 and up. (The 5V current available will decrease with increased load on the +/-12V rails since).

Perfect for powering single modules or a small desktop Eurorack setup. Can be connected to a power bus board and standard Eurorack power cables.
