N1408

The Mod. N1408 provides 4 independent High Voltage channels in a single width NIM mechanics. Each channel can provide a ±800V / 20 μA max output.
Channels have common floating return (common return insulated from the crate ground); HV outputs are delivered through BNC HV connectors. The HV output RAMP-UP and RAMP-DOWN rates may be selected independently for each channel in the range 1÷100 V/s in 1 V/s steps.

Safety features include:

• OVERVOLTAGE and UNDERVOLTAGE warning when the output voltage differs from the programmed value by more than 2% of set value (minimum 1V).
• Programmable VMAX protection limit.
• OVERCURRENT detection: if a channel tries to draw a current larger than its programmed limit, it enters TRIP status, keeping the maximum allowed value for a programmable time (TRIP), before being switched off.
• Channels can be enabled or disabled individually through the Interlock logic.

Module control can take place either locally, assisted by a Graphic color display or remotely, via USB, RS232 or RS485; the RS485 port allows to build a N1408’s daisy chain network (up to 32 modules). For remote operation, CAEN also provides GECO2020, a graphical application that allows to manage the N14xx HV Power Supplies (as well as all other CAEN Power Supplies).

Moreover, these units can be managed via CAEN HV Wrapper, a set of ANSI C functions bundled in a library, providing the software developer a unified software interface for the control of CAEN Power Supplies. This is a low level application in which the writing of the Control SW is assigned to the user. CAEN HV Wrapper is logically located between an higher level application, such as GECO2020, and the lower layer software libraries. It contains a generic software interface independent by the Power Supply models and by the communication path used to exchange data with them.
