The Universal Motor Controller UMC-3A is an update to the UMC-3. Through a new voltage booster, higher lens motor speeds are possible when using 12V supply voltages, like those found in many video cameras. Like its predecessor, the UMC-3A provides camera and lens remote control capabilities to film and video cameras that do not have a WRS radio built in. Up to 3 lens motors can be connected, while hand units communicate with the UMC-3A wirelessly or via cables. In addition, the UMC-3A provides support for the Lens Data Dilsplay for Focus Puller (LDD-FP) and its Lens Data Archive (LDA) options.
