FlexKraft offers a complete range of switch mode DC power supplies for industrial applications in harsh environments.
The compact and modular design offers many benefits to the user.
FLEXIBILITY
Besides regular voltage control and current control, FlexKraft HIGH POWER FACTOR
also offers power control that allows the use of a wide voltage and Low reactive power consumption throughout the range reduces
current output range. installation and electrical cost.

The FlexKraft rectifiers are designed to give the best electrical BLOCK SCHEMATIC DIAGRAM
performance in demanding industrial environments. The design
is based on primary switching technology.
The rectifiers consist of 1–10 power modules. Together with a
control module, they form a complete power supply.
