Overview
A7038 family is a 32 or 48 independent high voltage channels board available in different versions equipped with SHV or with DB37 connectors. The output voltage range is 0 ÷ 1 kV (20 mV set and 2 mV monitor resolution), with 100 µA maximum output current (2 nA set and 500 pA monitor resolution).
The channels share a Common Floating Return, which allows on-detector grounding, reducing the noise level. The board is available with either positive or negative output polarity.

DB37 connector
Single width (5 TE wide), 48 channels for Mod. A7038AN, A7038AP |
|
SHV connector
Triple width (15 TE wide), 32 channels for Mod.A7038STN, A7038STP |
Consult our connectors reference page for technical information.
The output voltage range is 0 ÷ 1 kV, with 2 mV monitor resolution. The maximum output current is 100 µA, with 500 pA monitor resolution.
Independently programmable for each channel:
| Output voltage: | 0 ÷ 1 kV | step: | 20 mV |
| Current limit (Iset): | 0 ÷ 100 µA | step: | 2 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 (Iset), it signaled to be in “overcurrent” and enter in a TRIP status: the channel is switched off after a programmable TRIP time. The output current is permitted to exceed Iset value, the channel behaves like a current generator only if the IMAX current value is reached. |
| Hardware VMAX and IMAX | maximum output voltage and maximum current value can be fixed, via front panel potentiometer, at the same common value for all the board channels. IMAX and VMAX values 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 (only for Multipin Connector versions). |
