SLIMLINE modular DC power supply systems


SLIMLINE SE power supply systems are built from individual modules with capacities of 800W (SLIMLINE 800 SE) and 2000W (SLIMLINE 2000 SE). The SLIMLINE SE rectifier modules are installed in 19" 1U carriers. Each carrier can accommodate up to five 48V- 800 SE modules or three 48V-2000 SE modules.

Systems with different battery capacities and load configurations can be created. Distribution modules are designed to fit 19" racks and are 1U or 3U high depending upon the number of output feeds required. The rectifier carrier, rectifier modules, battery protection devices and output distribution equipment forms a complete modular SLIMLINE SE power supply system (SLIMLINE Modular System ≡ SMS).

BENNING's smallest capacity power supply system (SMS 2400 SE) accommodates up to three rectifier modules (48V-800 SE) in a 1U 19" carrier together with a battery protection and load distribution unit (4000 SE) in a second 1U 19" enclosure.

The SMS 4000 SE increases the maximum power to 4000W. This system consists of a 1U carrier with up to five rectifier modules (48V-800 SE) plus the battery protection and load distribution unit 4000 SE .

Larger capacities up to 6000W (SMS 6000 SE) are possible using the 48V-2000 SE modules. A 1U 19" carrier can accommodate up to three of these rectifiers and can be combined with the battery protection and load distribution unit 6000 SE.

A capacity of up to 18000W (SMS 18000 SE) can be achieved by connecting in parallel three 6000 SE rectifier carriers. These can then be combined with the 3U 19" battery protection and load distribution unit 18000 SE. Even greater capacities can be realized by the parallel connection of further carriers.

A SLIMLINE control board is provided for rectifier control and monitoring purposes. A SLIMLINE MCU is available as an option for additional monitoring functionality. In the case of the SMS 2400 SE the SLIMLINE MCU is mounted in the rectifier carrier. In power supplies with greater capacity the SLIMLINE MCU is mounted in the battery protection and load distribution enclosure.

For more comprehensive control and monitoring functions, the remote mounted monitoring system MCU 2500 is available.
