SSC-02outdoor site solution cabinet for main-remote

rbs applications

the SSC-02 Site Solution Cabinet sup-plies -48 V DC power to Main-remote (M-R) radio base stations and auxiliary equipment. Physical space as well as prioritized power for auxiliary equipment such as transmission is also supported.

To provide security against AC power supply interruptions, battery backup functionality is ensured by built-in batteries or via connection to a BBS 6101 (for applications requiring very long battery autonomy or for cyclic battery operation).

Flexibility The SSC-02 is confi gurable to suit both small and large M-R confi gurations. DC output capabil-ity ranges from 2,0 kW to 8 kW. DC load circuit breakers are available from 2A up to 32A ,ensur-ing that virtually any M-R site confi guration can be supported.

The system supports one battery circuit breaker connected to the built-in battery bank. For very large backup needs, the battery bank can be daisy-chained to an extension BBS 6101 cabinet.

The cabinet features 9 HU of space for auxiliary 19” mountable auxiliary equipment.

All equipment, connections and the climate system are easily accessed via the lockable front door.

To facilitate operations, maintenance and spare parts handling, the power system mod-ules are the same as in the indoor system PBC 6200.

Climate Control SystemThe heat exchanger climate system ensures a suitable interior climate for the 19” equipment and power system. For the battery compartment an energy efficient active cooling system is used to ensure maximum battery lifetime and performance. Both climate systems work without air exchange with the ambient environment.

EnvironmentEarthquake Zone 4 capability will be available as an option at a later date.

Supervision and ControlThe power system controller features an LCD display and keypad for quick access to power system information at the site. The same information and more can be accessed remotely. Binary alarms can be connected to the network supervision system, via the site’s alarm collecting system. The power system controller’s binary outputs also supports a diesel generator On&Off control.
