Gavita Master Controller EL3

A grow light controller for up to 512 fixtures

The EL3 switches, dims, and boosts up to 512 fixtures across two zones, 256 per zone, from a single 8-inch color touchscreen. It reads power draw and driver-enclosure temperature per fixture, so a hot or failing driver shows up before it costs you a cycle. Sunrise and sunset dimming ease the room in and out of each photoperiod. Growers wire it to compatible Gavita 1930e, 1700e, 900e, or Sun System 1850 fixtures and run whole grow cycles on one schedule.

Scheduling and safety on the Master Controller EL3

High-temperature dimming pulls output back as a room heats, and high-temperature shut-off cuts the lights if it crosses the line. A spray feature dims fixtures during applications to guard against crop burn. It connects up to 16 Titan Controls sensors for VWC, EC, and VPD data and logs setting and alarm history over USB. One caveat: the EL3 drives Gavita e-series and Sun System 1850 fixtures, so confirm yours are on that list before wiring.
