Benning Slimline NG Telecom Rectifiers

Benning Slimline NG Telecom Rectifiers cover the entire array of mobile radio applications, from the mobile switching center (MSC for short) to the base station controller (BSC) to individual base transceiver stations (BTS). Consequently, the power supply systems safeguard the entire transmission technology (LTE, 5G, VOIP, TV, servers, etc.) against power failures.

Maximum Availability:

• very high reliability

• low mean time to repair (MTTR)

• reliable hot swap modularity

• decentralised parallel architecture

• remote monitoring via TCP/IP

• superior supply quality

  • sinusoidal input current, no reactive-power absorption (power factor ≥ 0.99)

Minimized Operating Costs:

• high efficiency > 97% even at partial load

• extremely high power density and, thus, low space requirements at the installation site

• sustainable investment reliability through pay-as-you-grow scalability up to 400 kW

• automatic synchronisation of the rectifier modules during replacement and retrofitting

• low expenditure for installation, commissioning and expansion

Flexible & Modular Component Concept:

The modular concept significantly lowers the cost and time expenditure in the installation and maintenance of the new SLIMLINE telecommunications power supplies at wireless sites which are being newly built or converted.

The SLIMLINE system is simply scalable and can grow in line with customer requirements – from 2 to 400 kW. Due to the high degree of modularisation, it is possible to plan, configure and deliver customised systems at very short notice. It is possible to combine rectifiers and inverters in one system. Both system components are monitored and configured by the MCU 3000 on a common interface.

All modules can be replaced during ongoing operation (hot plug). The SLIMLINE carrier with the appropriate quantity of rectifier modules and the assigned battery and consumer distribution create a complete, modular SLIMLINE power supply system.

Maximum operational reliability, minimum operating costs

The newly developed SLIMLINE NG power supply solutions are precisely tailored to the requirements of the telecommunications network operator. They include:

• optimum operational reliability

• maximum energy efficiency

• optimum user space

• flexibility (pay as you grow)

• modularity

They not only contribute significantly to the low total cost of ownership (TCO), they are also the basis for a clear reduction in installation and assembly times, as well as for simpler and more efficient maintenance possibilities in later operation.

Only one type of rectifier is required for systems within a power range of 2 kW to 400 kW. This simplifies stock management and logistics for the benefit of the owner as it is only required to keep one type of module in stock for all systems.

Optimum energy efficiency in the minimum user space

Individual rectifier modules with an output of 2000 W are available for creating complete power supply systems. The 19" 1H carrier can accommodate either five 48 V / 2000 W rectifier modules combined with a monitoring and control unit (SLIMLINE controller) or six rectifier modules. This gives a power rating of 10 kW or 12 kW per rack.

In this series of high-efficiency rectifiers, the power loss which occurs in the transformation of energy from alternating current to direct current has been reduced by up to 30% compared to the previous model. At the same time, the overall physical footprint of the rectifiers has been reduced by more than 33%.

A particularly impressive fact is that the SLIMLINE series works at efficiency in excess of 97% across a load range of between 50% and 90%. This creates substantial savings for telecommunications service providers which operate a number of systems in the field. Optionally, active power management can be enabled which determines the load required and automatically connects or disconnects the rectifier modules accordingly.

SLIMLINE NGcontroller – remote monitoring and reliability in a very compact space

The SLIMLINE NGcontroller is available for extensive control and monitoring functions. This is generally inserted into the SLIMLINE NG carrier as a module in the case of low power ratings. The 19" 1H carrier can accommodate either five 48 V / 2000 W rectifier modules combined with a controller module or six rectifier modules. In the case of power supplies with a greater power rating, the monitoring and control unit can be integrated into the cabinet door of the power supply system.

The controller monitors the entire power supply system and controls the power management for example. The system is structured to ensure that the power supply remains operational in the event of controller failure. The rectifiers continue to supply the system and the batteries, which is why the power remains at 100%. Therefore, failure is not critical to the process, and there is no need for controller redundancy. This lessens the space required and reduces investment and operating costs. Needless to say, a message appears in the event of a controller failure so that prompt steps can be taken to have the controller module replaced by a service technician at short notice.
