Consult our connectors reference page for technical information.
The output voltage range is 0 ÷ 6 kV with 10 mV monitor resolution. The Maximum output current is 20 μA with 50 pA monitor resolution. 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).
Independently programmable for each channel:
| Output voltage | 0 ÷ 6 kV | step: 100 mV |
| Current limit (Iset) | 0 ÷ 20 μA | step: 500 pA |
| HV 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. |
