6 Ch 12 kV / 1 mA Common Floating Return Board
A1523
The CAEN Mod.A1523 is a double width board (10 TE wide) that houses 6 independent high voltage channels, available with either positive or negative polarity. The channels share a Common Floating Return, which allows on-detector grounding reducing the noise level.

Consult our connectors reference page for technical information.
The output voltage can be programmed and monitored in the 0 ÷ 12 kV range with 1 V resolution. The maximum current full scale is 1 mA, with 100 nA Iset/Imon resolution.
The boards are provided with both current and voltage protections. If overcurrent occurs, the corresponding channel can be programmed either to turn off after a programmable trip time or to keep on providing the maximum allowed current. This last particular feature allows the module to work as current generator. The maximum output voltage can be set through a potentiometer to a value which is common to all channels and can be read out via software.
A global enable/disable connector allows to disable the channels when it is not terminated on 50 Ω. The HV Ramp-Up and Ramp-Down rates may be selected independently for each channel in the 1 ÷ 500 V/s range (1 V/s step).
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 |
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. |
The board features the CPE HV output connectors and the relevant coaxial cable connectors (Mod. A997) are also available.
