(ب) اتباع نظام التركيز المتوافق مع المحركات الرقمية وجهاز تعزيز 24 في المائة
ما توصّل إليه النقاش
- Preston follow focus نظاماً يمكن أن يعمل مع محركات رقمية من مصنّعين مختلفين بما في ذلك Heden وسكوربيو، ليس فقط Preston محركات.
- 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.
يعتمد على
- 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.
