Overview

The CAEN Mod.A3050 is a 8 V / 50 A / 300 W Power Supply Board developed for operation in magnetic field and moderate radioactive environment. One A3050 houses 2 floating (reversible polarity) 8 V / 50 A channels (300 W maximum output power per channel). The connector output voltage range is 2 ÷ 8 V with 5 mV monitor resolution; channel control includes various alarms and protections.

Consult our connectors reference page for technical information.

The board is provided with Remote Sensing Lines to compensate for the voltage drop over the connection cables.

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 software with 5 mV resolution and the output voltage can not be programmed beyond this value.
