Overview
The CAEN Mod. DT1470ET provides 4 independent high voltage channels in a desktop package (110/220 V AC powered). Each channel delivers up to ±8 kV and 3 mA, with a maximum output power of 9 W, reduced to 8 W when the output voltage exceeds ±3 kV. The output polarity of each channel can be selected independently.
The channels share a common floating return, insulated from the crate ground, and 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 50 nA Iset/Imon resolution, and the x10 Imon Zoom increases the current monitor resolution to 5 nA.
The module can be controlled locally, through a 2.8″ color touchscreen LCD display with a completely redesigned user interface, or remotely via USB 2.0 or Ethernet.
A complete set of free software tools is available to control the unit: GECO2020, with a user-friendly GUI, and the CAEN HV Wrapper library for custom software development. EPICS and LabVIEW are also supported.
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.
