Overview
The CAEN Mod.A3512 12 kV / 1 mA Power Supply Board is developed for operation in magnetic field and radioactive environment. One A3512 houses 6 individual floating (up to 5 V between each other) 12 kV / 1 mA channels. The output voltage can be set with 1 V monitor resolution.
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 1 V resolution and the output voltage can not be programmed beyond this value.

Consult our connectors reference page for technical information.
The output current is monitored with 100 nA resolution; if a channel tries to draw a current larger than its programmed limit it is signalled to be in Overcurrent condition; the SY1527 system detects this state as a fault and reacts according to the setting of the TRIP parameter.
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. |
| Overtemperature detection | It is possible to monitor board temperature and to check board status thought TEMPERR > 65°C. When the board status is TEMPERR all channels are switched off. |
| 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. |
