01

Key features

  • ● Full digital control, high stability
  • ● Integrate the functions of open loop, constant voltage, constant current, constant power, power regulation (zero-crossing) control, LZ (phase-shifting zero-crossing) control, online power distribution, etc.
  • ● With true RMS voltage and current acquisition function, active power control
  • ● With multi-channel switch and analog programming interface
  • ● Isolation technology is used for input and output interfaces, with strong anti-interference ability
  • ● When the power is adjusted, the power can be distributed online to reduce the impact on the power grid
  • ● Standard configuration RS485 communication interface
  • ● Expandable PROFIBUS, PROFINET, MODBUS TCP communication option card
  • ● Heavy load design, strong overload capacity
