For those that want to be able to dim their lights with custom sunrise/sunset/moonlight phases (as well as having the ability to monitor temperature) this is a great unit to get. This item replaces the old Apex Jr with the only difference being this unit includes a display. The VDM module provides separate control of 4 channels, up to 3-4 drivers per channel (if you need more than 4 channels you can add another VDM module to this base unit). The VDM also allows you to control the speed of your pumps (assuming your pumps are compatible).
This item is compatible with our 0-10V Nano drivers, Mean Well "D" series drivers and the HLG-185-42B driver. We HIGHLY recommend you buy the 2 Channel Apex to Light Dimming Cable for easy connection from the driver to the Apex unit (one cable per 2 channels).
The Apex Jr comes with the following items:
The Variable Speed/Dimming Module is included in this product.
