Variable Speed / Dimming module

The Variable Speed/Dimming Module (VDM) provides the
ability to control the Aqua Illumination LED lighting systems as well as adding
4 additional variable speed ports. The Aqua Illumination’s interface allows for
the independent control of both the blue and white LEDs. In addition,
sunrise/sunset, cloud and lightning simulation are also available. The 4
variable speed ports (0-10V interface) allow precise 0 to 100% control of Tunze
stream pumps as well as dimming of some compatible ballasts. You can control
them based on time of day, in response to feed timers, or any event you can
think of using the powerful Apex programming language.
