2. 803x Series Overview
The 803x power supply series provides 8 or 16 independent HV channels, whose control can take place
either locally thanks to a 2.8" Touchscreen Graphic color LCD display or remotely, via USB 2.0 or Ethernet.
The units are available in three formats: double width NIM mechanics, 19” rack module and Desktop case.
NIM and Desktop versions feature 8 channels, the 19” rack units can house either 8 or 16 channels.
5 output ranges are available (100V/10mA, 500V/10mA, 4kV/3mA, 6kV/20µA and 6kV/1mA), with either
positive or negative polarity; all units are provided also in “mixed” version, with half of the channels
positive and half negative. 100V channels are delivered through BNC connectors, other versions feature
SHV’s.
The HV output RAMP-UP and RAMP-DOWN rates may be selected independently for each channel.
Safety features include:
•OVERVOLTAGE and UNDERVOLTAGE warning when the output voltage differs from the
programmed value by more than 2% of set value (minimum 10V).
•Programmable VMAX protection limit via front panel trimmer; common to all channels
•Programmable IMAX protection limit via front panel trimmer; common to all channels
•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.
•Common Interlock logic for channels enable/disable and individual inputs signal for channel Kill
function.
A complete set of Software Tools is available to control these units; the User can freely download low
level libraries, LabVIEW driver and Graphical application software.

it allows to adjust the hardware maximum voltage VMAX common to
all the channels. Its value can be read out via software.
IMAX
trimmer
it allows to adjust the hardware maximum current IMAX common to
all the channels. Its value can be read out via software.
Alarm signal
As an Alarm condition is detected, pins 2 and 3 (- and +) are closed; the contact can be
used to switch an external device supplied by an external source, otherwise the VB and
GND references can be used to provide a TTL compatible level on pin 2 and 3.
In the first case (externally supplied device) the maximum allowed ratings are:
•Maximum voltage between + and -: 12V
•Maximum sink current across + and -: 100mA
In the latter case, to produce a TTL compatible Alarm Out, pin 3 (+) must be
connected with pin 4 (VB) and pin 1 (GND) with pin 2 (-); see the diagram:
Interlock signal
A schematic diagram of the Interlock input is shown in the figure on the
left, where the diode is part of opto-coupler stage.
Interlock means that channels are hardware disabled. The following table
explains the interlock operation:

The front panel Interlock LED is ON when the INTERLOCK is active; as INTERLOCK is active, channels are turned off at the fastest
available rate, regardless the RAMP DOWN setting. To reset the Interlock flag, all switches must be placed on KILL and then on OFF.

Trip
Max. time an "overcurrent" can last (seconds). A channel in "overcurrent" works as a current generator;
output voltage varies to keep the output current lower than the programmed value. "Overcurrent" lasting
more than set value (1 to 9999) causes the channel to "trip". Output voltage will drop to zero either at the
Ramp-down rate or at the fastest available rate, depending on Power Down setting; in both cases the
channel is put in the off state. If trip= INFINITE, "overcurrent" lasts indefinitely. TRIP range: 0 ÷ 999.9s;

Remote Control
Module control can take place remotely, via USB or Ethernet; an external PC is required (supported OS:
Windows 7 or later; Linux kernel Rel. 2.4 or later). The connection can be performed via VT emulators
(such as Tera Term), or via one of the available tools (see below). The 803x Power Supplies family is
identified as SMART HV by the available software tools. Control option on the Touchscreen must be set
to REMOTE.
Software tools
GECO2020
CAEN GECO2020 is a graphical application that allows to control the 803x Power Supplies (and all other
CAEN Power Supplies). Once the unit is correctly installed, download and install the GECO2020 software
package related to your OS; follow the instructions in the GECO2020 User manual and the unit will be
ready to be operated. For more info, please visit www.caen.it (products>firmware/software section).
CAEN HV Wrapper
CAEN HV Wrapper is a library, available either as a set of ANSI C functions or LabVIEW™VI’s. Such set
provides 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. It contains a generic
software interface independent by the Power Supply models and by the communication path used to
exchange data with them.
CAEN HV Wrapper is logically located between a higher-level application, such as GECO2020, and the
lower layer software libraries. For more info, please visit www.caen.it (products>firmware/software
section).
Power Supply Modules LabVIEW Instrument Driver
Power Supply Modules LabVIEW Instrument Driver is a set of VI’S, developed for LabVIEW 2017 and later
releases (LabVIEW™is a Trademark of National Instruments Corp.), that allow to configure and monitor
all parameters of remotely controlled CAEN Programmable HV Power Supply modules. Host PC shall run
LabVIEW 2017 or later releases and NI-VISA Run-Time Engine 17.
To install the Power Supply Modules LabVIEW Instrument Driver, go to CAEN web site in the “Software”
area, download the Power Supply Modules LabVIEW Instrument Driver installation package and follow
the Set Up instructions.
