DRd Power Control

  • When it comes to fluorescent dimming, Unison DRd can handle it all: two- and three-wire dimming ballasts with standard modules, DALI ballasts with the DALI option board, and 0-10V ballasts with the FLO option board. And DRd doesn’t stop at fluorescent control; there is reverse-phase dimming for electronic low-voltage transformers and a full range of load options, including LED.


  • DRd Power Control (with Echo)

    Simply smart power control

    The Unison DRd Power Control enclosure with Echo provides and routes modular power for 16 control stations and 16 power controllers or panels. The enclosure can house up to 48 circuits of dimming and on/off relay control. Broadcast DALI and 0-10V outputs, combined with line-voltage dimming and switching capabilities make DRd Power Control with Echo an incredibly flexible and powerful tool.

    Powerful peace of mind.  

    We ensure that your system stays reliable, even when the power goes out. DRd Power Control's built-in power supply protects your system, providing you with uninterrupted service -- even in emergency situations. In the event of a power outage, optional RideThru technology will keep processors energized for up to ten seconds, while power is transferred to an emergency source. For additional security, the optional BatteryPack module keeps your system functional for up to 90 minutes following a power disruption, so your system is ready to respond as soon as power returns.

    It's easy being green.  

    The Unison Echo® system was specifically developed with your energy concerns in mind. Keeping green has never been easier - Echo's complete line of products gives you maximum energy savings while adhering to the growing number of industry energy codes, such as ASHRAE 90.1, CA Title 20/24 and IECC, all without breaking the bank.

    DRd Power Control (with Paradigm)

    A great combination

    When you select Unison Paradigm® Control in the DRd enclosure, you get the best of two worlds: unparalleled lighting control and full-featured dimming. The enclosure supports a Paradigm Architectural Control Processor (ACP), and an optional Paradigm Station Power Module for use with Heritage and Paradigm stations. When used with the Paradigm ACP, the enclosure unlocks support for the NetConnect Ethernet networking, featuring ETC's Net3™, powered by ACN, along with DMX512A, RS-232 serial-, and contact-closure interfaces.

    Building on the best features of the original, ETC has redesigned the Unison dimming enclosure by adding substantial capabilities to maximize its already considerable power handling. The new Unison DRd has more power density than other dimming systems, while packing even more features into the enclosure.
