The Trolley Bus from Befaco is a power module with bus board for the Eurorack modular system. It is extremely powerful and delivers impressive +12 V: 5000 mA / -12V: 2500 mA / 5V: 4000 mA. To ensure that the trolley bus can deliver this power, a powerful 135W power supply is included in the scope of delivery. The power supply of the module is provided by the bus board with high-quality DC/DC converters, which is also included in the scope of delivery. 28 modules can be connected to this bus board. The trolley bus is capable of powering a large 4-5 row 104TE system on its own and has plenty of resources left over for extremely power hungry module. The two USB charging ports benefit from the high voltage of 4000mA on the 5V line; this can easily charge a smartphone or power two desktop devices.
