The OMS and OMS can be integrated into RBS and RBS Product Overview The RBS , a member of the RBS family, is an outdoor RBS. The RBS consists of an outdoor cabinet with either. Ericsson shall have no liability for any error or damage of any kind resulting from Variants The following variants are available: • RBS with a heater.

The fan speed will automatically decrease as the demand for the cooling declines. Help Center Find new research papers in: The SCU activates the heater.
Get advice on custom projects erlcsson replacement parts. Every fan increases its speed to cool down the cabinet. 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.

The SCU runs the internal fans at different speeds. These are shown in the document Trademark Information. Log In Sign Up. Controlled mode The controlled mode is the rba runtime mode.
Remember me on this computer. The original dbs 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. 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. This improved system operating efficiency and reduced maintenance expense.
Cold Start The SCU goes into cold start mode if the temperature sensor measures low temperatures in the cabinet at startup. The sturdy frame and durable, cleanable metal mesh media is perfect for outdoor environments.
The AC-fed heater is suggested for standard use. The DC-fed variant should be used for a DC-supplied RBS and gbs there are requirements for equal phase load ericzson minimization of the feeding fuse size. Click here to sign up. The internal fans maintain a cooling airflow inside the cabinet by forcing internal air through the interior part of the heat ericcsson, 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 result was increased operating expense because of service calls to remote locations, fan replacements, and technicians spending additional hours cleaning internal system components.

An optical indicator on the front panel of the SCU will also be activated. Filter complete with support strap riveted to frame and part number and rev level metal stamped into frame. Information on the internal cabling can be found in Non-RF Connections. The SCU adjusts fan speeds to maximize heater effect. The air is then forced through the exterior part of the heat exchanger and expelled through the upper rear of the cabinet. Eicsson heater is then activated and the internal fans run at different speeds to maximize heating.

The SCU will maximize output from the heater by running the fans at different speeds if the temperature continues to decrease after activation of the heater. No extra SCU, temperature sensor, or heater is required for the extended climate solution. There are two variants of heaters: The exact behavior and thresholds are dependant on the RBS configuration.
Eventually, equipment would overheat and trigger alarms for emergency maintenance. The electronics inside the cabinet require forced air cooling for wattage dissipation and to keep the system operating at ideal conditions. When 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.
