The Trolley Bus has 28 slots for Eurorack modules powered by four high-quality DC-DC converters.

Its +12V rail is divided into two independent sections (top and bottom), providing each up to 2500mA. It allows

you to keep sensitive modules isolated and enhances the voltage stability under load.

Both the -12V and 5V rails are common for the entire bus board and provide up to 2500mA and 4000mA

respectively.

Be aware that the zone under the converters can be hot under heavy current loads.
