What the thread found

• Preston follow focus systems can work with digital motors from different manufacturers including Heden and Scorpio, not only Preston-branded motors.
• The 24V booster supplies constant 24 volts to motors to maintain consistent rotation speed regardless of whether the main system is powered by less than 24 volts.
• MDR-1 follow focus units can operate on 12V power without a booster, but motors will run at reduced speed and power output.
• With a 24V booster connected, motors operate at approximately twice the speed compared to 12V operation.
• Some older 900MHz MDR-1 models had external 12-24V converter boxes, while microwave versions incorporated the voltage converter into the upper tray assembly.
• MDR-2 and microwave MDR-1 versions share the same power connector pinout.

Depends on

• The discussion does not specify whether all MDR models universally benefit from 24V boosters or only certain versions.
• Motor speed difference between 12V and 24V operation is described qualitatively as roughly doubled, but exact specifications are not provided.
• The age and specific hardware variant of an MDR-1 unit affects its compatibility with external boosters versus built-in converters.
• No information about whether non-Preston digital motors require additional configuration or adapters for Preston systems.
