Ericsson RBS-6102

The original system design did not include proper air filtration, so the fans and cabinet were exposed to harsh contaminants, causing it to fill with dirt and debris. Any unit that is able to send temperature information has the ability to affect the fan speed.

When the temperature in the cabinet is acceptable, a signal is sent to the power system to supply DC power to all units in the cabinet.

The DC-fed variant should be used for a DC-supplied RBS and when there are requirements for equal phase load or minimization of the feeding fuse size.

Examples of this are during cold startup and unplanned MP downtime. It is fastened with screws on the surface inside the cabinet and connected to the SCU. The DC heater is equipped with a second heating circuit which is also activated at this second stage. Eventually, equipment would overheat and trigger alarms for emergency maintenance.

It has a total cooling capacity of 2. The electronics inside the cabinet require forced air cooling for wattage dissipation and to keep the system operating at ideal conditions.

Because the exterior part of the heat exchanger is supplied with ambient air, the internal temperature is limited by the temperature rba the air outside the RBS. The result was increased operating expense because of service calls to remote locations, fan replacements, and technicians spending additional hours cleaning internal ericssin components.

The SCU adjusts fan speeds to maximize heater effect. The internal fans maintain a cooling airflow inside the cabinet by forcing internal air through the interior part of the heat exchanger, connected to the exterior part that is cooled by the exterior airflow, and then expelling it through the front openings of the climate system back into the cabinet.

The AC-fed heater is suggested for standard use. The exact behavior and thresholds are dependant on the RBS configuration. The heater is then activated and the internal fans run at different speeds to maximize heating.

The SCU will perform the following steps in order should the temperature sensor measure temperatures in the cabinet below the threshold until the temperature starts to increase: The solution was a metal mesh filter designed for exact fit within the front air intake louver to eliminate air bypass and provide total system filtration.

In the controlled mode, the Main Processor Ericason controls the fans. UAF will work with operations and maintenance personnel to find the best solution and provide a free sample for fit check and performance evaluation. The ericsskn and the external fans will speed up in parallel to counter the increasing internal temperature. rbx

The fan speed will automatically decrease as the demand for the cooling declines. The heater is deactivated and all the internal fans maintain a constant speed. The SCU activates the heater.

The sturdy frame and durable, cleanable metal mesh media is perfect for outdoor environments. Erjcsson the temperature within the cabinet is acceptable, a signal is sent to the power system to supply DC power to all units in the cabinet. The extended climate system supports up to 12 Ericdson. Every fan increases its speed to cool down the cabinet.

The SCU will maximize output from the heater by running the fans at different speeds if the temperature continues ebs decrease after activation of the heater.
