4 Ch Reversible 5.5 kV/20 µA NIM HV Power Supply High Accuracy Module (USB)
N1471H
The CAEN Mod. N1471H provides 4 independent High Voltage channels in a single width NIM mechanics. Two and one channel versions (N1471HA and N1471HB) are also available. Each channel can provide a ±5.5kV / 20 µA output. 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 single width, 4 channels for Mod. N1471H, N1471HA (2 Ch), N1471HB (1 Ch) |
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 1nA Iset/Imon resolution. Zoom for Imon increases resolution to 50 pA. Power supply control can be performed either locally, assisted by a Graphic color display or remotely, via USB, RS232 or RS485, the latter allowing to build a daisy chain network of modules N14XX. It is also controllable via TCP/IP by the Smart Fan Unit of CAEN NIM8301.
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:
|
Channels |
can be enabled or disabled through the Global Interlock logic. |
|
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. |
|
Hardware VMAX |
programmable MAX 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 NIM 8301 crate:
