Overview
The CAEN Mod. A7040 is the new high density general purpose power supply offering you all the safety, performance and control of a completely independent channel technology at the cost effective price of a distributor!
Well suited for large Silicon detectors arrays, this single width board (5 TE wide) family houses 48 independent High Voltage channels available with either positive or negative polarity, equipped with DB37 connector. The maximum output current is 1 mA, with 2 nA monitor resolution. The maximum output voltage can be set through a potentiometer to a value which is common to all channels and can be read out via software.
The A7040 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. Channels are delivered through DB37 connectors.

Consult our connectors reference page for technical information.
The output voltage range is 0 ÷ 100V, with 0.2 mV monitor resolution. The maximum output current is 1 mA with 2 nA monitor resolution.
Independently programmable for each channel:
| Output voltage | 0 ÷ 100 V | step: 2 mV |
| Current limit (Iset) | 0 ÷ 1 mA | step: 20 nA |
| V Ramp up/down |
1 ÷ 50 V/range | 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. |
| Safety Board Interlock | this protection disables the HV generation when the HV outputs are not connected to their loads. |

- Ramp Up / Ramp Down
Max. time an “overcurrent” is allowed to last (seconds); common to all channels. A channel in “overcurrent” works as a current generator; output voltage varies in order to keep output current lower than the programmed value. “Overcurrent” lasting more than set value, causes the channel to “trip”. Output voltage will drop to zero either at Rampdown 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
