To improve the safety of wind power plant towers, Wieland Electric has launched the podisLED as an addition to its podis power bus system. In the past, fluorescent lamps with emergency light functions had a number of disadvantages when used with wind power plant towers, including relatively short maintenance intervals, short service life and were labour intensive and time consuming to install.
The podisLED makes installation, maintenance and operation easier and safer, whilst providing reductions in cost and time.
The LEDs are not subject to maintenance intervals and they immediately switch to full light output even at low temperatures.
The podisLED has a rating of IP65, making it suitable for use in harsh ambient conditions. The LEDs are designed for extreme ambient temperatures of -40°C to 70°C, and can be used in CCV (cold climate version) and HCV (hot climate version) temperature ranges.
With their operating voltage of 24V DC and their low power consumption of 5W per LED, it is possible to implement a maintenance friendly, economical emergency lighting solution with a central supply according to DIN EN60598-22. This central solution facilitates the necessary replacement of the buffer battery while saving time and costs. Even in towers with a height above 100m, voltage drops pose no problem thanks to the wide input voltage range of 15-30V DC with full light output.
The short circuit and overload protection integrated into every single lamp means that errors do not spread and are easily located.
