A0/A1 24-48VDC red obstruction controller system is energy efficient

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 three watts, it’s the most efficient of its kind on the market, enabling the use of smaller batteries and panels for a much lower overall system cost compared to competing systems.

“Like every product we make here at Dialight, our goal with this controller is to minimise waste and expense while ensuring maximum flexibility,” said Michael Sutsko, Dialight’s Group Chief Executive. “This low-power solution conserves battery life and offers steady-on or configurable flash rates to meet any application.”

Backed by Dialight’s signature 5-year full-performance warranty, the controller and monitoring system lets operators set flash rates at 20, 30 or 40 seconds per minute to meet FAA requirements and for avian protection, as well as 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 on the enclosure.

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. The system is compatible with Dialight Vigilant Low (L-810) and Medium (L-864) Intensity LED obstruction lights.
