Cooler improves the reliability of cellular coverage
Improving the reliability of cellular coverage, Laird's AA-480 series outdoor cooler keeps people connected during a power outage by protecting the emergency batteries used in wireless base stations.
When the power to a cellular antenna tower goes out, emergency batteries in the base station turn on to provide power for up to six hours. But battery life is significantly reduced by exposure to temperatures outside the optimal range. That is why many wireless base station operators take measures to ensure that emergency batteries are kept at the proper temperature extending the life of those batteries and ensuring more reliable cellular coverage during power outages.
The AA-480 series protects these critical batteries by providing greater cooling power and increased reliability than other units currently on the market. And the AA-480 accomplishes this using less energy and taking up less space compared to similar units. With a Coefficient of Performance rating of 1, they are nearly 50% more efficient than standard air-to-air units offered today. This saves installation and maintenance costs for users as well as space inside the battery cabinet.
Due to its robust, steady-state construction, Laird’s 480W AA-480 series also requires less maintenance, cutting the total cost of ownership as well as the time spent travelling to and from these sometimes remote locations. It can also be easily retrofitted as a substitute for compressor based air conditioners used in medical diagnostic and analytical instrumentation for cooling and heating applications where maximising system uptime is required.
Other key features include an input power which accommodates a nominal/float voltage of 24/28 or 48/56VDC, fan control for reduced noise and power cycle testing up to 100,000 cycles.
