Overview
The power supply A7042 is a single width board (5 TE wide) that houses 48 Independent high voltage channels. The A7042 is available in different versions equipped with DB37 or Radiall Multipin connector:
|
Radiall multipin connector
Single width (5 TE wide), 48 channel for Mod.A7042 |
|
DB37 connector
Single width (5 TE wide), 48 channel for Mod. A7042A, A7042B |
Consult our connectors reference page for technical information.
The A7042 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 ±30 V. The board is available with either positive or negative output polarity. The output voltage range is 0 ÷ 500V, with 1 mV monitor resolution. The maximum output current is either 500 μA or 1 mA with 1 nA or 2 nA monitor resolution.
Independently programmable for each channel:
| Output voltage | 0 ÷ 500 V | step: 10 mV |
| Current limit (Iset) | 0 ÷ 500 μA or 0 ÷ 1 mA | step: 10 nA or 20 nA |
| V Ramp up/down |
1 ÷ 100 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 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. |
