The CAEN Mod A7460 is a single width board (5 TE wide) that houses 12 independent high voltage channels.
The channels share a Common Floating Return, which is insulated from the chassis/crate ground. This feature may help to minimize problems of ground-loops. The board is available with positive or negative output polarity Channels are delivered with SHV connectors. Consult our connectors reference page for technical information.
The output voltage range is 0 ÷ 6000 V, with 10 mV monitor resolution. The output channels offer dual current ranges (software selectable):
|
High Power: |
0 ÷ 1 mA |
||
|
I set resolution: 5 nA |
|||
|
I mon resolution: 2 nA |
|||
|
High Resolution: |
0 ÷ 0.1 mA |
||
|
I set resolution: 5 nA |
|||
|
I mon resolution: 0.2 nA |
Independently programmable for each channel:
|
Output voltage: |
0 ÷ 6000 V |
Step: 10 V |
|||
|
Current limit (Iset): |
0 ÷ 1 / 0.1 mA selectable |
Step: 5 nA |
|||
|
V Ramp up/down: |
1 ÷ 500 V/s |
Step: 1 V/sec |
|||
|
TRIP parameter |
0 ÷ 999.9 s; 1000 s = Infinite |
Step: 0.1 s |
Safety features 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.
CAEN provides a complete software range to control, monitor and configure its Power Supply products.
