4 Ch Reversible 5.5 kV/20 µA NIM HV Power Supply High Accuracy Module (USB/Ethernet/T.screen)
N1471HET
The CAEN Mod. N1471HET provides 4 independent High Voltage channels in a double width NIM mechanics. 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.

Consult our connectors reference page for technical information.
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.
Safety features allows the module to perform as a current generator and includes:
|
Channels can be enabled or disabled |
can be enabled or disabled through the Global Interlock logic. |
|
Overvoltage and Undervoltage warning |
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. |
|
Hardware VMAX |
programmable VMAX protection limit. |
|
Safety Board Interlock |
common Interlock logic for channels enable/disable and individual inputs signal for channel Kill function. |
Module control can take place either locally, assisted by a Graphic colour display, or remotely, via USB (1) or RS485 (1). It is also controllable via TCP/IP (2) by the Smart Fan Unit of CAEN NIM8301 crate:
