Highly Efficient Modular Systems For an Efficient Installation of DC Charging Stations
With the new BELATRON modular series, BENNING provides equipment suppliers and operators of EV charging stations with high-performance charging modules and systems which are tailored exactly to the requirements of rapid charging.
The systems combine highest operational safety and reliability, maximum energy efficiency and optimally usable "user space".
The concept of modular components is the basis for offering significantly reduced installation and assembly times as well as easier and more efficient maintenance during later operation.

Minimum operating costs
Due to the excellent efficiency even for the partial-load range, the ongoing operating costs are minimized without compromising voltage quality.
Maximum availability and minimum MTTR (Mean Time To Repair)
For the new BELATRON modular series, BENNING combines the advantages of maximum reliability and shortest repair times (MTTR) in a product that meets highest requirements regarding the availability and quality of a safe and reliable power supply of EV charging systems. Due to the use of high-quality components and their generous dimensioning in the critical path, the design of the BELATRON modular system is optimally adapted to the harsh conditions of rapid charging with high currents and voltages.
The "hot swap" capability allows each module to be replaced in less than ten minutes which corresponds to a maximum reliability of 99.9999 %.
General Module Data:
- Nominal power: 87.5 kW (@ 875 V)
- three phase
- input per module:
-
- 3 x 400 V /50 Hz, 3 x 150 A (max.)
- output per module:
-
- 200 V to 950 V, max. 100 A
- Max. efficiency: 97.0 % at nominal load
- hot plug
- compact, modular, fail-safe
Battery charger output:
- DC output voltage range: 200 VDC - 950 VDC
The characteristics show the linear change of the charging power in relation to the battery charging voltage at different charging currents of 100 A, 200 A and 400 A.
Highest Economic Efficiency
- low installation and operating costs
- efficiency of 97 %
- only little space required due to high power density and an optimized installation concept
- maximum quality of supply
- mains current consumption with low harmonic content (THDi < 3 %)
- sinusoidal input current, no reactive power consumption (power factor ≥ 0.99, adjustable)
