Voltage choice is mainly a system layout decision. It affects driver selection, wiring distance and the number of heads in one set.
24V is common for smaller modules and compact OEM units. It is simple to integrate when the output requirement is not very high.
48V is usually selected for higher head counts or longer running systems. It can reduce current on the power side, but the driver must be matched correctly.
Do not choose voltage only from the label. Check module quantity, available power supply, cable length, installation space and local safety requirements.
Project note: Send the planned head count and cabinet layout when asking for a recommendation. The driver can then be matched more accurately.
