Overview

The CAEN Mod.R1570ET provides 4 or 2 (depending on version) independent High Voltage channels in a 19″ rack unit (110/220V AC Powered). Each channel can provide a ± 15 kV max voltage, 1 mA max current and a 10 W max power. 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 Lemo HV 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 20 nA Iset/Imon resolution. Zoom (x 10) for Imon increases resolution to 2 nA. 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 or Ethernet, taking advantage of the new GECO2020 Control Software.

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.

Output channels

2/4 channels, Common Floating Return, Positive or Negative Polarity (requires internal setting)

Output ranges
  • 15 kV / 1 mA (IMonRange = High)
  • 15 kV / 100 µA (IMonRange = Low) – Imon Zoom Active
Max. Ch. Output Power
  • 10W (<10 kV)
  • 7W (>10 kV)
Vset Resolution

Iset Resolution

Imon Resolution
  • 20 nA  (IMonRange = High)
  • 2 nA    (IMonRange = Low) – Imon Zoom Active
Vmax

0 ÷ 15100 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: < 1 V; current~5 mA; 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)
