main DT55xxE


4 Channel Desktop HV Power Supply Family with Ethernet & USB

  • 4 independent HV channels in a compact desktop module
  • up to 6 kV / 3 mA output ranges
  • Available with positive, negative or mixed polarity
  • SHV coaxial output connectors
  • Very Low Ripple
  • Under/overvoltage alert, overcurrent and max. voltage protection
  • Status output Channel ON/Status LEDs
  • Remote control via USB2.0 and Ethernet
  • Interlock logic for unit enable and individual channel kill
The DT55xxE is a new CAEN Power Supply Family providing 4 independent High Voltage channels in a compact Desktop form factor.The units are available with either positive, negative or mixed polarity. High Voltage outputs are delivered through SHV connectors. DT55xxe units can be controlled, via USB or Ethernet, taking advantage of the new GECO2020 Control Software.

Different versions are available spanning from 500 V to 6 kV and from 20 µA to 3 mA (4 W maximum), meeting the needs of a wide range of applications.

A Zoom option is available for Imon. This feature enhances the current monitoring, increasing the resolution of a x10 factor.

The HV output Ramp-Up and Ramp-Down rates can be set independently for each channel in the range 1÷500 V/s in 1 V/s steps (1÷100 V/s for DT5519E).

Safety features
arrow Overvoltage and Undervoltage warning when the output voltage differs from the programmed value
arrow Programmable hardware VMAX protection limit
arrow Overcurrent detection: if a channel tries to draw a current larger than its programmed limit, it is signalled to be in "overcurrent" and is switched off. The high voltage will drop to zero at a rate determined by the value of "Ramp-Down" for that channel.
arrow Common Interlock logic for channels enable/disable and individual input signal for channel Kill function.
