Overview
The CAEN Mod.N1570 provides 2 independent High Voltage channels in a double width NIM mechanics. 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.

Consult our connectors reference page for technical information.
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.
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. |
Available Options:
- A1480 DC Input Power Equalizer.
Technical Specifications

- Output ranges
- 15 kV / 1 mA (IMonRange = High)
- 15 kV / 100 µA (IMonRange = Low) – Imon Zoom Active
- Max. Ch. Output Power

- 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)
- Voltage Ripple
20 ÷ 1000Hz - 7 kV / 250 µA. Typical: 7 mVpp / Maximum: 10 mVpp
