The NIM power supply family provides a series of Independent High Voltage channels in 1U (N14xx) or 2U (NDT14xx, N14xxET, N1570) NIM module. N14xxET/NDT14xx families provides 4 channels, N1570 2 channels, while N14xx are available in versions housing 4, 2 or 1 channels (N14xx, N14xxA, N14xxB). Each channel can provides up to 15 kV and 3 mA max output. The output polarity is independently selectable for each channel that features common floating return (common return insulated from the crate ground); HV outputs are delivered through SHV or LEMO-HV connectors.
The HV output ramp-up and ramp-down rates may be selected independently for each channel in the range 1 ÷ 50 V/s or 1 ÷ 500 V/s in 1 V/s steps. The modules feature high Iset/Imon resolution (up to 1 nA). Each unit is provided with Imon Zoom, this feature increase Imon resolution up to 50 pA. Power supply control can be performed either locally, assisted by a 2.8” color touch screen or OLED display or remotely, via Ethernet, USB, RS232, RS485, the latter allowing to build a daisy chain network of modules N14xx. For those module not featuring the Ethernet interface, it is also possible to setup a control via TCP/IP by the Smart Fan Unit of CAEN NIM8301. The NDT modules can work either as a standard NIM module or a desktop power supply thanks to the 110-220 AC plug. A complete set of software tools is available to control these units, from low level libraries to graphical application software. 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 10 V).
|
|
Overcurrent detection
|
when a channel attempts to exceed the programmed current limit, it signalled to be in “overcurrent” and enter in a TRIP status. The output voltage is varied to keep the current below the programmed limit for a programmable TRIP time, then the channel is switched off. If TRIP is set to “constant current mode”, the channel behaves like a current generator.

VMAX
|
Programmable VMAX protection limit.
|
|
Safety Board Interlock
|
Common Interlock logic for channels enable/disable and individual inputs signal for channel Kill function.

Available Options:
N14xx modules are provided with a USB VCP interface and can be programmed via PC by connecting the PC USB port with the N14xx USB B-type port; the featured controller (FT232BM chip) requires a driver available on this page or at www.ftdichip.com
