Overview
The CAEN Mod. R1471HET provides 4 or 8 (depending on version) independent High Voltage channels in a 19″ rack unit (110/220V AC Powered). Each channel can provide a ±5.5 kV max voltage and a 20 µA max current. The output polarity is independently selectable for each channel.
Channels have common floating return (common return insulated from the crate ground); HV 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 1 nA Iset/Imon resolution. Zoom for Imon increases resolution to 50 pA.
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.

Consult our connectors reference page for technical information.
A complete set of free software Tools is available to control this unit: GECO2020 with user friendly GUI and CAEN HV Wrapper library for custom SW development. EPICS and LabVIEW also supported.
Safety features allows the module to perform as a current generator and includes:
|
Interlock |
Common Interlock logic for channels enable/disable and individual inputs signal for channel Kill function |
|
Overvoltage and Undervoltage |
warning when the output voltage differs from the programmed value by more than 2% of set value (minimum 10V) |
|
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 |
|
VMAX |
Programmable VMAX protection limit |
