DT5534E

The CAEN Mod. DT5534E is a compact desktop module housing 4 independent high voltage power supply channels, each delivering up to 6 kV and 1 mA, with a maximum output power of 4 W. The unit is available with either positive or negative output polarity, as well as in a mixed version with 2 positive and 2 negative channels.

The HV outputs are delivered through Radiall R317580 SHV coaxial connectors; for further technical information, consult our connectors reference page. Ramp-up and ramp-down rates can be set independently for each channel from 1 to 500 V/s in 1 V/s steps. The module offers 5 nA Imon resolution, which can be extended by a factor of 10 in a lower range selectable via software.

All functional parameters can be programmed and monitored via USB 2.0 or Ethernet, and a complete set of software tools is available to control the unit, from low-level libraries to graphical application software.

The module also includes dedicated safety features that allow it to operate as a current generator. A common safety board interlock logic enables or disables the channels globally, while individual input signals provide a kill function for each channel. An overvoltage and undervoltage warning is issued when the output voltage differs from the programmed value by more than 2% of the set value (minimum 10 V). If a channel attempts to draw a current higher than its programmed limit, it enters TRIP status and holds the maximum allowed value for a programmable time (TRIP) before being switched off. A programmable hardware VMAX protection limit is also available.
