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.
Topology
Using an isolation dual back-to-back full bridge topology, the AL3000R provides efficient and reliable solid state power conversion in both regenerative and non-regenerative modes. The AL3000R is available in either standard version (max current available at max voltage) or in Constant Power version using a more flexible range where higher output current is available at lower voltage settings. This is illustrated in the diagram to the right.
Front Panel Controls
Multi-turn potentiometers provide precision control over voltage and current set points. Settings can be locked so no accidental adjustment can be made.
Two large LED Segment displays provide continuous readouts of voltage and current to the load.
AL Manager Software
Intuitive Windows based AM Manager control software turns any PC into a remote operator console. The AM Manager software provided a higher level of power supply control than available from the front panel.
