Most current Allen & Heath products use a switched-mode power supply, so all that is needed is the correct mains power lead for the local supply.
These PSU’s can accept power from mains supplies throughout the world and tolerate a wide range of power frequencies and voltages.
Next to the mains socket (AC MAINS IN) the allowed range of voltage and frequency range is listed (as well as the maximum power usage in Watts).
i.e. 100 - 240V, 47 - 63Hz
The rating of any fuse is also listed where applicable.
If your unit does not have a voltage range specified, it is a linear supply rather than switched-mode
e.g.
RPS11
AC mains input voltage selector found at the rear of the unit.
Check the correct fuse is fitted for the selected mains input voltage; both will be listed on the rear panel as well as in the User Guide.
RPS15
Internally wired to operate from one of the following standard settings: 100V, 120V, 220V, or 240V.
This unit is shipped pre-wired for the country in which it is to be used.
