Maximum availability for essential areas of application in industry

In areas of industry where it is crucial for the operating systems to perform with maximum availability in the interests of safety and profitability, no shutdown periods can be allowed, for example in the petrochemical industry, in the generation and distribution of energy and in highly automated applications, including traffic management. In such areas, the plant, the control systems and the monitoring technology must be fully protected against failure or faults in the electrical supply.

It’s precisely here that battery-backed modular DC solutions operating in a parallel redundant mode have proven their worth. To such an extent that individual modules can even be swapped over without the need for interruption, quickly and straightforwardly. At the same time, these modular systems have proven their excellence in terms of the highest conceivable reliability, uncomplicated scalability, the maximum of flexibility, simple servicing and low operating costs.

With BENNING’s TEBECHOP SE product line, it offers a new generation of highly affordable modular rectifiers which meet the challenges of sensitive, process-critical systems to an unrivalled extent: capable of operating in parallel with lead-acid or NiCd energy storage when it comes to battery-supported standby power solutions.

Rectifier systems
Individual, flexible, robust

Diverse range of options for meeting customer requirements with BENNING’s modular rectifier systems, thanks to the range of housings available. There are wall-mounted or floor-standing enclosures, whilst smaller systems can use all-in-one cabinets which also accommodate the batteries. BENNING’s modular approach comprises a range of practical power supply and load distribution solutions for installation in the system cabinets. When it comes to battery and load distribution, BENNING supplies a range of suitable system cabinets which will also house the modules of the MCU 3000 Monitoring and Control Unit 3000.

Modular DC converters can be easily combined

The 1/5, 19” wide DC converters are ideal for modular systems. Not only are they based on the same mechanical platform but also the front panel design provides for inter-compatibility. This means that combinations of these modules can be easily installed in shared system cabinets.

Maximum availability and flexible power expansion (pay as you grow) on the basis of n + r redundancy
TEBECHOP SE rectifier systems combine straightforward, flexible power adjustment (scalability) with high availability and excellent energy efficiency. The essential building blocks of these rectifier systems are power modules with reliable hot-plug technology which can be increased when power output requirements increases. Redundant systems (e.g. n + r redundancy) can be designed in order to achieve additional uptime availability.

Low MTTR (Mean Times To Repair) and low maintenance and servicing costs
TEBECHOP SE rectifiers combine optimum reliability and shortest repair times in a system which meets the highest requirements for availability and quality in a reliable power supply system. Thanks to the “hot-swap” capability, each module can be easily replaced in less than 10 minutes. If replacement modules are available on site, the corresponding emergency intervention, or just routine servicing and repair tasks, can be readily carried out by the plant operator’s trained staff. On this basis, repair times (MTTR) can be minimised simultaneously combined with maximised system uptime.

High output in the most restricted space

Thanks to the compact dimensions (3U) of TEBECHOP SE modules and the low power loss due to high efficiency, you can operate up to ten TEBECHOP 13500 SE plug-in rectifiers with 135 kW of output power or fifty TEBECHOP 3000 SE modules with 150 kW of output power in a single system cabinet measuring 2000 mm x 600 mm x 600 mm (H x W x D).

High efficiency, even at partial load

TEBECHOP SE series rectifiers offer very high levels of efficiency even within the load range of 25% to 90%. In systems with a high output, significant savings in electrical power can be achieved using this highly efficient range of rectifiers.

Straightforward, safe operation combined with extensive reporting and monitoring functions

As an option, the MCU 3000 can be used for control and remote monitoring of the power supply systems. Controls are logically tailored to the user’s requirements, and offer clear, precise and comprehensive indication of all of the required readings and settings. The MCU’s advantages include an integrated web server and, in addition to remote maintenance which, for example, provided by BENNING’s 360° service solution, enables the option of connecting up to various network topologies.

On higher-output power systems, the MCU can be housed in the power supply system’s cabinet door. This version comprises a 10.4” touch screen. The MCU is also available as a 19” rack insert (1U). The front of the controller module then features a 1.8” display, a USB 2.0 interface (to accommodate a WLAN stick, for example) and an ethernet port.
