DNPLVM-AB: This plate snaps on the V-mount plate hardwired in the Neo ballasts as well as the Colorist panel and features a Gold-mount socket to accept Gold-mount batteries. It fits on both the Neo Bicolor ballasts (DTNeo and DTNeo+) and Neo multicolor ballast (DTN7C+). It also features a 2-pin D-tap input receptacle to accept 15v DC power from the ProCali external power-supply with 2-pin D-Tap male (0CAPS15-105AB) so you do not have to only rely only on batteries.
