The CAEN Mod. NDT1471 provides 4 independent High Voltage channels in a double width NIM mechanics. Desktop operation (110/220V AC Powered, needless a NIM crate) is also supported. Each channel can provide a ±5.5 kV max voltage and a 300 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.

SHV connector NIM double width, 4 channels for Mod. NDT1471 |
Consult our connectors reference page for technical information.
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 5nA Iset/Imon resolution. Zoom (x 10) for Imon increases resolution to 500 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.
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:
|
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. |
|
Safety Board Interlock |
common Interlock logic for channels enable/disable and individual inputs signal for channel Kill function. |
