16 Channel 9 kV / 50 µA Common Floating Return Board
A1590
The CAEN Mod. A1590 board is a double width board (10 TE wide) that houses 16 Independent high voltage channels delivered through Radiall 52 pin HV connectors. The board is available with either positive or negative output polarity.

Consult our connectors reference page for technical information.
The channels share a Common Floating Return, which allows on-detector grounding reducing the noise level. The floating return is insulated from the crate earth up to ±50 V (with a 65 V hardware limit). The output voltage range is 0 ÷ 9 kV with 10 mV set and monitor resolution while the Maximum output current is 50 μA with 100 pA monitor resolution.
Independently programmable for each channel:
|
Output voltage: |
0 ÷ 9 kV |
step: 200 mV |
|
Current limit |
0 ÷ 50 μA |
step: 1 nA |
|
V Ramp up/down: |
1 ÷ 500 V/sec |
step: 1 V/sec |
|
TRIP parameter: |
0 ÷ 999.9 s; 1000 s = Infinite |
step: 0.1 s |
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. |
|
Overcurrent detection |
when a channel attempts to exceed the programmed current limit, it signalled to be in “overcurrent” and enter in a TRIP status. The output voltage is varied to keep the current below the programmed limit for a programmable TRIP time, then the channel is switched off. If TRIP is set to “constant current mode”, the channel behaves like a current generator. |
|
Hardware VMAX |
maximum output voltage can be set, via front panel potentiometer, at the same common value for all the board channels. VMAX value can be read out via software. |
|
Safety Board Interlock |
this protection disables the HV generation when the HV outputs are not connected to their loads. |
