Consult our connectors reference page for technical information.
The HV output RAMP-UP and RAMP-DOWN rates may be selected independently for each channel in the 1 ÷ 500 V/s range with 1 V/s steps. The module features 100 pA Imon resolution. Features include current monitor resolution extended by 10x in a Lower range (selectable via software). Functional parameters can be programmed and monitored via USB 2.0 or Ethernet. A complete set of software tools is available to control these units, from low level libraries to graphical application software.
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 (±0.5% of the set value, ±3 V). |
| 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 of. If TRIP is set to “constant current mode”, the channel behaves like a current generator. |
| Hardware VMAX, IMAX | Programmable VMAX, IMAX protection limit. |
| Safety Board Interlock | common Interlock logic for channels enable/disable and individual inputs signal for channel Kill function. |

- Trip
Max. time an “overcurrent” is allowed to last (seconds). A channel in “overcurrent” works as a current generator; output voltage varies 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. If trip= INFINITE, “overcurrent” lasts indefinitely. TRIP range: 0 ÷ 999.9 s; 1000 s = Infinite. Step = 0.1 s
