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 ÷ 1.5 kV, with 10 mA maximum output current (12W channel max output power) and 50 mV set and monitor resolution. The board is available with either positive or negative output polarity and equipped with SHV coaxial connector. The board channels can be enabled according to the interlock logic. The HV RAMP-UP and RAMP-DOWN rates may be selected independently for each channel in the 1 ÷ 500 V/s range (1 V/s step).
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 signaled 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. |
