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 signals an “overcurrent” condition and enters TRIP status. The output voltage is adjusted to keep the current below the programmed limit for a programmable TRIP time, after which the channel is switched off. If TRIP is set to “constant current mode”, the channel behaves as a current source.

  • 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:

  • A1480 DC Input Power Equalizer.

  • x 10 Imon Zoom, increasing Imon resolution to 500 pA.

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
