Overview

The CAEN Mod. R1471ET provides 4 or 8 (depending on version) independent High Voltage channels in a 19″ rack unit (110/220V AC Powered). Each channel can provide a ±5.5 kV max voltage and a 300 µA max current. 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 1÷500 V/s in 1 V/s steps. The module features 5nA Iset/Imon resolution. Zoom (x 10) for Imon increases resolution to 500 pA.
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.

19” 2U,  4/8 channels for Mod. R1471ET

Consult our connectors reference page for technical information.

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:

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

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
