Overview
The CAEN Mod. DT1471ET provides 4 independent High Voltage channels in a Desktop package (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.
Channels are delivered with SHV connector (Radiall R317580 HV coaxial). 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 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:
|
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 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. |
|
Hardware VMAX |
Programmable VMAX protection limit. |
|
Safety Board Interlock |
common Interlock logic for channels enable/disable and individual inputs signal for channel Kill function. |
