The CAEN Mod. N1471 provides 4 independent High Voltage channels in a single width NIM mechanics. Two and one channel versions (N1471A and N1471B) are also available. Each channel can provide a ±5.5kV / 300 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.
The HV output Ramp-up and Ramp-down rates may be selected independently for each channel in the range 1В500 V/s in 1 V/s steps. The module features 5nA Iset/Imon resolution. A Zoom option (x 10) is available for Imon, increasing resolution to 500pA.

SHV connector

NIM single width, 4 channels for Mod. N1471 (2 Ch for N1471A, 1 Ch for N1471B)

Consult our connectors reference page for technical information.

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:

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 “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.

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:

    ± 1 V

    Alarm Output

    Open collector, 100 mA maximum sink current

    Interlock input

    LOW: <1 V; current~5mA; HIGH: 4÷6 V

    Ramp Up/Down

    1÷500 Volt/s, 1 Volt/s step

    Trip

    •  Max. time an “overcurrent” can last (seconds). A channel in “overcurrent” works as a current generator; output voltage varies in order to keep the output current lower than the programmed value.
    • “Overcurrent” lasting more than set value (1 to 9999) causes the channel to “trip”.
    •  Output voltage will drop to zero either at the Ramp-down rate or at the fastest available rate, depending on Power Down setting; in both cases the channel is put in the OFF state.
    • Trip range: 0 ÷ 999.9 s; 1000 s = INFINITE. Step = 0.1 s (If trip= INFINITE, “overcurrent” lasts indefinitely).

    Voltage Ripple

    • 20 ÷ 1000 Hz: Typical: 10 mVpp / Maximum: 15 mVpp
    • 1 ÷ 20000 kHz: Typical: 3 mVpp / Maximum: 8 mVpp
