The Mod. DT8033 provides 8 independent 4 kV/ 3 mA (6W) channels in a desktop package (110/220V AC Powered). Each channel can provide a 4 kV max voltage and a 3 mA max current (up to 6W). The unit is available with positive, negative and “mixed” (4 positive and 4 negative) channels.

Channels outputs are delivered through SHV connectors. The HV output RAMP-UP and RAMP-DOWN rates may be selected independently for each channel in the range 1÷500 V/s in 1 V/s steps. The module features 10 nA Iset resolution.

Module control can take place either locally thanks to a 2.8″ Touchscreen Graphic color LCD display with a completely redesigned user interface or remotely, via USB 2.0 or Ethernet.

A complete set of Software Tools is available to control these units; the user can freely download low level libraries, LabVIEW driver and Graphical application software. Moreover a built-in web interface (Coming Soon) is available to easily controls the module with no need to install software on a PC. The user can monitor the status of the module and configure the HV parameters for each channel in real time.


Safety features include:

  • OVERVOLTAGE and UNDERVOLTAGE warning when the output voltage differs from the programmed value by more than 2% of set value (minimum 10V).
  • Programmable VMAX protection limit
  • OVERCURRENT detection: if a channel tries to draw a current larger than its programmed limit, it enters TRIP status, keeping the maximum allowed value for a programmable time (TRIP), before being switched off
  • Common Interlock logic for channels enable/disable and individual inputs signal for channel Kill function.
