The CAEN Mod. A1520P houses 12 positive HV channels; each output channel has an independent floating ground. The output voltage can be programmed and monitored in the range 0 ÷ +500 V in 1 mV steps (17 bit resolution). All output channels are provided with Remote Sensing Lines to compensate for the voltage drop over the cables.
The board is provided with both current and voltage protections. For each channel, it is also possible to set an output current limit in the 0 ÷ 15 mA range, in 250 nA steps.
The output current is monitored with 25 nA resolution. If overcurrent occurs, the relevant channel can be programmed either to turn off after a programmable trip time or to keep on providing the maximum allowed current: this particular feature allows the module to work as current generator.
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 ÷ 50 V/s range (1 V/s step). Moreover the floating channels allow on-detector grounding, thus allowing to reduce the noise level. The board features the AMP 75-pin output connector.
Channels are delivered with AMP75 connectors. Consult our connectors reference page for technical information.

Vmon vs. Vout accuracy* |
±40 ppm * Most boards can operate indifferently whether the SY1527 mainframe is supplied with 50 Hz or 60 Hz AC power supply; the A1520P series, instead, requires a factory calibration, so the User should check if the board is calibrated for operation at the right frequency (50 Hz or 60 Hz). |
