Overview
The CAEN Mod. A3540 4 kV / 1 mA Power Supply Board is developed for operation in magnetic field and radioactive environment. One A3540 houses 12 floating (up to 5 V between each other) 4 kV / 1 mA channels. The output voltage can be set with 500 mV monitor resolution.

SHV connector |
Consult our connectors reference page for technical information.
If the output voltage differs from the programmed value by more than 3% of voltage full scale range, the channel is signalled to be either in Overvoltage and Undervoltage condition. Moreover, for each channel, a voltage protection limit SVMAX can be fixed via software with 500 mV resolution and the output voltage can not be programmed beyond this value.
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 by more than 3% of voltage full scale range. |
|
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 channel. IMAX and VMAX values can be read out via software. |
