    The LSQ5 power source with Direct Control Technology (DCT)

LSQ5 power source:

The power source with an output of 420 A and Direct Control Technology

The LSQ5 ensures the optimum arc energy. It uniquely adjusts to different weld processes. Unlike conventional power sources with inverter technology, the LSQ5 with Direct Control Technology controls its switching transistors without any fixed clock frequency according to the needs of the weld process. Without any delay, the energy needed for the process is provided instantly.

The flexible fine tuning is done by a central processor. The CPU continuously analyzes the weld process and current/voltage values on the basis of data obtained and optimally drives the switching transistors of the power section. This results in an extremely high efficiency and a low temperature development.  

The power source can be configured with only two buttons and four LED indicators. For world-wide usage, voltages can be configured without opening the power source.

  • Benefits - LSQ5

    Benefits - LSQ5

    • Up to ten times the control speed of traditional inverter technologies – resulting in an excellent control performance and thus shorter intervention times.     
    • Generally enhanced welding characteristics. Software replaces hardware: Less components increase the system reliability – also in continuous operation.      
    • Future-proof: New functions are included via software upgrades in an effortless and cost-effective way.      
    • External fans without filters: No soiling inside the power source.      
    • Fail-safe design: The operating temperature of the power unit is only 20°C above the ambient temperature.      
    • Low weight, small footprint: The power source can be installed at any height using the wall brackets.
