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.

An external temperature sensor is connected to the SCU that controls the heater. Because the exterior part of the heat exchanger is supplied with ambient air, the internal temperature is limited by the temperature of the air outside the RBS.

This metal mesh filter was designed eriscson help a major wireless telecom provider address ongoing maintenance issues.
Help Center Find new research papers in: The DC-fed variant should be used for a DC-supplied Ericsso and when there are requirements for equal phase load or minimization of the feeding fuse size.
No extra SCU, temperature sensor, or heater is required for the extended climate solution. Figure 3 shows the climate system block diagram.
Filter complete with support strap riveted to frame and part number and rev level metal stamped into frame. The electronics inside the cabinet require forced air cooling for wattage dissipation and to keep the system operating at ideal conditions. The heater is deactivated and all the internal fans maintain a constant speed.
The air is then forced through the exterior part of the heat exchanger and expelled through the upper rear of the cabinet. 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.
Eventually, equipment would overheat and trigger alarms for emergency maintenance. Examples of this are during cold startup and unplanned MP downtime.

Hot Start The SCU goes into hot start mode if the temperature sensor measures high temperatures in the cabinet at startup. The AC-fed heater is suggested for standard use. The fan speed will automatically decrease as the demand for the cooling declines. The SCU will perform the steps in reverse order as 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.
An optical indicator on the front panel of the SCU will also be activated. Trademark List All trademarks mentioned herein are the property of their respective owners. Shop Online Click to browse our most popular Telecom replacement filters available for purchase online.

It has a total cooling capacity of 2. 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 heater is equipped with a second heating circuit which is also activated at this second stage. The result was increased operating expense because of service calls to remote locations, fan replacements, and technicians spending additional hours cleaning internal system components.

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:
