  • Introduction:

    The Small Cell Cabinet (SCC) is single compartment structure. The housing is formed by overall welding to enhance cabinet strength. The internal area is a 6U space for mounting 19” equipment, of which 4U-space is reserved for distribution equipment (e.g. Battery, Fiber Distribution Panel & Router) and 2U space is for the Power System. Equipment mounted in the SCC, can be pulled out horizontally. Cabinet door is provided with 3-way lock. The cabinet is furnished with axial fan at the top and Air Inlets for ventilation on the door. The top canopy can be opened to mount and repair the fan, when necessary.

     

    The Power System provides constant power for telecommunication equipment power demand, mounted in the SCC. The 2U subrack has been designed with a modular Controller, Rectifier (1600W) & Inverter (1000VA), which can be equipped in one 19” shelf. The Rectifier requires a nominal input of 220 Vac and provides an output of -48 Vdc to power the DC loads and also maintain a charged battery. The Inverter provides an output of 220Vac to power AC loads.
