Fast, Bi-directional DC Power Supplies
The AL3000R series power supplies are robust, economical, easy to use solid-state equipment. Developed for intensive use on production lines, these supplies are ideal for research and development laboratories. Due to their high switching frequency combined with multi-level switching technology, they provide a clean DC output voltage with low ripple and short reaction times and a high conversion efficiency of more than 92%. They can operate in two quadrants, supply and absorb energy from the load with line regeneration. The power range is from 5KW up to 500KW with parallel option up to 4MW and 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 range to ensure maximum power to the load. The AL3000R is equipped with a modern and simple user interface which makes setup and parameter readings very simple and intuitive. These units are packaged in a wheeled cabinet (low and medium power levels) or stationary cabinet.
Programmable via serial RS485 optional USB, LAN or optical fiber. Four digital I/O and four analog I/O support eary 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 voltage drop along the cables (up to 10% of the F.S.). They handle abrupt load variations with recovery times of less than 1 mS for load variations of 50%.
All the equipment can be fitted with dissipative brushless DC motor control (BLCD) module for the dissipation of energy coming from the load.
