Overview
Unison DRd power modules are designed for use in all DRd enclosures. Whether you need forward phase or reverse-phase SCR dimming, relay control, or specialty power control Unison DRd has you covered.
Most modules provide two circuits of control for a wide range of applications. All modules feature modular installation and removal, fully magnetic circuit breakers, and rock-solid construction.

- Per-circuit LED indicators
- Mechanical held air gap relay
- Integral bonded heatsink
- Integral temperature sensor
FILTERING
- High quality toroidal choke filters (see module chart for rise times)
DIMMING PERFORMANCE
- Dimming of 2 and 4-wire fluorescent ballast is dependent on lamp ballast combination. 4 wire fluorescent control requires optional 0–10 V control card
- Phase dimming performance for LED lamps varies considerably depending on the manufacturer and model. Visit http://www.etcconnect.com/compatibility/ for details on a variety of specific lamp sand information on how to send samples to ETC for testing
- PhaseAdept (LED) modules provide forward- or reverse-phase dimming and are compatible with any ETC Unison DR, Unison DRd or Sensor enclosure, including legacy products
- ELV modules provide forward- or reverse- phase dimming and are compatible with Unison DRd enclosures
