Fast power supplies AL3000 series are robust, economical, easy to use static equipments. Developed for intensive use on production lines are ideal for research and development laboratories. Due to their high switching frequency joined to the multilevel switching technology they provide a clean DC source in low ripple with short reaction times and a high conversion efficiency> 95%. They can also absorb energy from the load through the BLCD option that draws it on the resistors. The power range goes from 5KW up to 500KW with parallel option up to over 4MW with a range of voltages from 10V up to 1000V. The operating modes provide constant voltage CV, constant current CC, constant power and internal resistance simulation. The CP models provide output in constant power supplying twice the current in the mid voltage to ensure maximum adaptation to the load. Equipped with a modern and simple user interface which makes setup and parameter readings very simple and intuitive. They are realized in table rack (low powers), in wheeled cabinet (medium powers) or cabinet.


Programmable via serial RS485 optional USB, LAN or optic fiber. 4 digital I / O and 4 analog I / O they guarantee a perfect integration with automatic test lines The output voltage can be regulated with continuity from 0 to the maximum value, as well as the current, power, and the internal resistance. All devices are equipped with "sensing" for the compensation of the drop along the cables (up to 10% of the F.S.). They bear abrupt load variations even with recovery times of less than 1 mS for load variations of 50%.


All the equipments can be fitted with dissipative BLCD module for the dissipation of energy coming from the load.
