The CAEN 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.
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.
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 SY 1527 system detects this state as a fault and reacts according to the setting of the TRIP parameter , namely:
- TRIP=infinite ( = 1000 s)
The output current is permitted to exceed the programmed limit; if the maximum output current value is reached the channel behaves like a constant current generator.
- TRIP=finite (< 1000 s)
The output current is permitted to exceed the limit only for programmed time interval and then is switched off.
The TRIP time (i.e. the maximum time an Overcurrent condition is allowed to last) can be programmed in 0.1 s steps.
The maximum output voltage (VMAX Hardware) can be fixed, through a potentiometer located on the front panel, at the same common value for all the board channels and this value can be read out via software.
