When a message board fails in a heavily traveled location and safety is compromised, the only option is to repair and maintain during off-peak hours. But Clary created a solution that overcame this costly problem.
The Colorado Department of Transportation (CDOT) deploys message boards as part of the ITS infrastructure along freeways. One message board failed frequently and repair was expensive and complicated due to its location, available personnel and time constraints. Located on a heavily traveled freeway, off-peak maintenance was the only time possible. A mile of cones, three trucks and five personnel on overtime were regularly called on to service the message board at a cost of $5,500.00 per week.
Clary solved this problem by installing the SP 1250U. This model has an input voltage range of 75Vac to 155Vac while outputting 120Vac with very high tolerances. With the wide input voltage range, the Clary unit was able to tolerate the voltage variation caused by the lights cycling on and off while protecting the message board electronics at the same time. Since the installation of the Clary unit, the CDOT has not had to repair or reset the message board control system.
ETSI provides a radio and visual navigation system for landing and take-off of passenger and freight aircraft in Antarctica. Clary's proven solution is the answer to keep the system running.
ETSI designed a mobile sled which includes a radio tower and rotating beacon. This sled is towed to the runway to mark the approach path for landing aircraft. The system is powered by a stationary generator that operates when planes land or takeoff. A very long electric cable is used for connection when the sled is deployed to the runway. Because of cable length, significant voltage loss is experienced. A highly reliable low-temperature-capable UPS system was needed on the sled in order to maintain the safety margins necessary to deliver stable power.
Clary recommended its SP 1250PD-R product because of its proven performance in cold to frigid environments. This “off the shelf” product provided the customer with an economical and reliable solution. With a wide input voltage window of 85 to 130Vac, the SP 1250PD-R was able to take the reduced voltage due to the line loss and produce continuous 120Vac. Should the generator fail, the Clary unit’s batteries provide the system with four to six hours of additional run-time.
