Modular Two-quadrant power supplies high-performance AL3000 series

AL3000 Series power supplies capable of sink and source energy from the load, based on the evolution of the previous series and offer superior performance, including:

Accuracy up to 0.1%
reduced ripple with the use of multi-phase conversion
Simple parallel connection of several units
Modular configurations of complex systems

Due to their structure (double IGBT conversion) are very hard machines, developed for intensive use on both production lines and testing laboratories of research and development
Through a sophisticated multi-control system can make a perfect fit with the parameters of the load, which becomes particularly important in applications with high dynamics and precision.

The section control provides the sophisticated management of energy and the return of a series of electrical measurements with remarkable accuracy.
local controls have to be set by the operator and / or remote to be driven directly from the production lines via analog / digital interfaces and RS485.
Using a special software you can change all the control parameters for the desired response or a complete dynamic adaptation to the system under test.

Multiphase Technology

Conversion technology adopted in these multi-phase power supplies has resulted in a significant reduction in output ripple, better performance in speed of response, reduction of output capacity and greater accuracy.

System modularity

AL3000 series is a modular power supplies that can meet many needs, are composed of:

Power supply module
Regenerative module (optional) RGN
chopper module with resistors (optional) BLCD
Standard output module PUB or constant power module PUBCP

RGN block allows regenerative energy from the load to the grid and correct the power factor obtaining a power factor greater than 0.95 in both absorption and regeneration.
BLCD chopper dissipative useful in cases where the regenerated energy from the load is not significant and does not justify the use of the module RGN
PUB standard output block can provide the voltage and current rating
PUBCP block of constant power output can deliver and absorb a constant power in the range from the rated voltage to half of it, in fact to 1 / 2 Vout is able to provide or absorb 2In
NOTE:
AL3000 Series can be configured without blocks RGN BLCD when there is not energy to be regenerated.

Multiple output configuration
different module of PUB, can be connected at same power unit to obtain multiple outputs
Parallel operation
Several units can be easly paralleled also by using heterogeneous power unit
