  • Retains Dimming Control

    What do you mean when you say your power taps retain dimming control?

    The power tap is installed between the luminaire and the photocontrol as shown here. It allows for power to passthrough to the photocontrol device on top of it so as to switch the light on/off.

    However, some units have 2 or 4 additional contacts added so as to allow for dimming control of the lights. The dimming signals control the power fed to the lamp thereby varying the brightness appropriately to save on power. There are a number of dimming protocols to achieve this like DALI, DMX, 0 - 10V, DSI etc.

    More info can be gathered from this blog.

      What is the difference between the tap with 5 pins (3 contacts and 2 dimming) and 7 pins (3 contacts and 4 dimming)? As in why would i need 4 dimming contacts instead of 2? Also can you provide me with a reference on the dimming protocols here?
