Overview
The CAEN Mod. A1592 is a single width board (5 TE wide) that houses 8 independent high voltage channels equipped with SHV connectors.

Consult our connectors reference page for technical information.
The HV 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 65 V hardware limit). The HV ramp-up and ramp-down rates may be selected, for each channel, in the 1 ÷ 500 V/s range (1 V/s step).
The board is available with either positive, negative or mixed output polarity. The Mixed version comes with 4 positive and 4 negative channels. The output voltage range is 0 ÷ 9 kV, with 200 mV monitor resolution. The output channels offer dual current ranges (software selectable):
| High Power: | 0 ÷ 200 µA | I set resolution: 4 nA | I mon resolution: 1 nA |
| High Resolution: | 0 ÷ 20 μA | I set resolution: 4 nA | I mon resolution: 50 pA |
Independently programmable for each channel:
| Output voltage |
0 ÷ 9 kV | step: 200 mV |
| Current limit | 0 ÷ 200 μA | step: 4 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. |
| Remote Enable/Disable | front panel independent contacts available for all channels. |
| 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. |
