Essential Info

Ballast Dimmer - 0-10V Driver
All your commercial dreams come true.
The new INSTEON Ballast Dimmer is two products in one: A 0-10V control module for electronic dimming ballasts and a two-relay control module for traditional non-dimming fluorescent light ballasts. Installed alongside your fixture's existing fluorescent ballast, Ballast Dimmer adds INSTEON control and dimming to a wide range of commercial-centric fluorescent lighting. And the best part: Since INSTEON uses your installations existing electrical wiring for command and control, there's no need to tear up the walls or spend hours in (tight/awkward/precarious) spaces running new electrical wiring.

Shine with 32 Brightness Levels.
Whether your goals are to conserve energy or to add a touch of dimmable elegance, the INSTEON Ballast Dimmer delivers both. Ballast Dimmer can dim electronic dimmable ballasts that respond to a 0-10VDC input signal. Depending on the electronic ballast, you may be able to smoothly dim your fluorescent lights as low as 3%, providing reduced power consumption when a room is unoccupied and helping to create atmosphere with reduced lighting levels.

Your two-for-one relay solution.
No need for dimming? Ballast Dimmer can be configured to operate as a dual-relay switch for non-dimming ballasts, controlling two ballasts with a single module. Depending on your needs, you can use one ballast dimmer to vary the light output in a single large fluorescent fixture, powering only the lamps you need when you need them. Install a single INSTEON switch or keypad and let scenes provide your dim and bright illumination modes. And since Ballast Dimmer is installed per-fixture, your overhead lighting customization is sure to be unique.

Ready for commercial buildings..
Many commercial installations need more than a single split-phase 120V supply can provide. That's why we've built in an auto-detecting, power supply that can handle input voltages from 100-277VAC at 50 or 60Hz. Whatever your building voltage and frequency, Ballast Dimmer has you covered.

Reliable wireless communication.
Ballast Dimmer was built from the ground up with patented INSTEON Dual-Band communications technology, leveraging the best powerline signaling with far-reaching and phase-bridging RF communication. Dual-Band becomes that much more important in multi-phase buildings, making it possible to install Dual-Band INSTEON keypads and switches on entirely different electrical phases.

Control every fixture from a single button.
Ballast Dimmer excels at simplifying your lighting control system. Install a single Keypad Dimmer to control all of the hidden Ballast Dimmers and you won't have to teach someone how to turn the lights on or off. In a conference room, program the Keypad to recall a mode for Presentation that dims all of the overhead fluorescent fixtures, turns off the lights closest to the projection screen and lowers the screen. In a lobby, configure a Keypad to quickly switch between Morning, Day and Afterhours where the overhead illumination intensity responds to business hours, all with no central controller necessary. The Ballast Dimmer can remember 400 lighting scenes each with different light levels and fade on/off rates

    Been waiting a long time for this one! Works as a standard dimming light device- paired right up with my Vera. Using it to control a Cree CR14 0-10V LED fixture, the dimming control is very precise. I am surprised at how loud the relay is when the light turns off! Make it as quiet as the micro relays, and if it lasts 5 years without failing- it will be a 5 star product.
