Dialight, Farmingdale, N.J., launched its new A0/A1 Red Controller System, what is said to be the most energy efficient solution for lowering DC power consumption.

The system is designed for the control and monitoring of Vigilant obstruction signals on typical A0 and A1 tower types, including radio, communication and meteorological towers, as well as wind turbines.

Drawing just under 3 watts, the new controller and monitoring system lets operators set flash rates at 20, 30 or 40 seconds per minute to meet FAA requirements, and features a steady-on mode. The controller can be mounted at the base of the structure for easy installation and access on a universal 24-48V DC input. The enclosure can be secured with a padlock for security.

The onboard monitoring system measures current flow into the marker lights, triggering a report or alert via contact closure if voltage is out of spec. Each controller can accommodate a maximum of 16 L-810 side markers or 8 L-810 markers and one L-864 beacon.
