Overview
The Mod. DT1471HET 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 20µA 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 1 nA Iset/Imon resolution. Zoom for Imon increases resolution to 50 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.

Radiall R317580 HV coaxial connector for DT1471HET |
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:
| 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. |

- Vmax
- 0 ÷ 5600 V Absolute maximum HV level that the channel is allowed to reach, independently from the preset value Vset.
- Output voltage cannot exceed the preset value Vmax. The accuracy is 1 % ± 5 V
- Vmax resolution
± 1 V
- Alarm output
Open collector, 100 mA maximum sink current
- Interlock input
LOW: <1V; 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: 12 mVpp / Maximum: 20 mVpp
