The CAEN Mod. N1470ET provides 4 independent High Voltage channels in a double width NIM mechanics. Each channel can provide a ยฑ8 kV max voltage, a 3 mA max current and a 9 W max power (8 W max power when output voltage is larger than ยฑ3 kV). 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 1รท500 V/s in 1 V/s steps. The module features 50nA Iset/Imon resolution. Zoom (x 10) for Imon increases resolution to 5nA.

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:
|
Overvoltage and Undervoltage warning |
when the output voltage differs from the programmed value by more than 2% of set value (minimum 10V). |
|
Overcurrent detection |
when a channel attempts to exceed the programmed current limit, it signalled to be in โovercurrentโ 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 โconstant current modeโ, 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. |
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:
